Complete pre-trip inspection checklist for truck drivers

By The Schneider Guy

Estimated reading time: 4 minutes  

As a truck driver, performing a CDL pre-trip inspection is one of the most common and repeated tasks you will complete. Pre-trip inspections help truck drivers ensure their tractor and trailer are safe to operat e before hitting the road.  

Keep reading to learn what a p re -trip inspection is and what should be on a p re -trip inspection checklist .      

What is a pre-trip inspection?  

A pre-trip inspection includes checking over the tractor and trailer a truck driver will be operating . A pre-trip should be completed before the operation of a vehicle :  

• At the beginning of a driver’s shift.
• Any time a new trailer is picked up.
• After a 10-hour break.

A thorough inspection usually takes anywhere from 30 minutes to one hour and should be logged as on-duty, not driving (line 4) .

The indispensable CDL pre trip inspection checklist is one of the most important rituals of a driver's day. Industry veterans know this routine like the back of their hands—it's that vital to the trade— but new drivers struggle with how to remember their CDL pre trip inspections, especially for the exam.

Drivers are required to complete this walkthrough at least every 24 hours, after their mandatory 10-hour break. A detailed inspection can safeguard not only your safety but also that of everyone else on the road.

This article will walk you through an exhaustive checklist to follow before every trip, as well as the potential costs of not doing so. We've designed this list with YOU in mind, so we're throwing in some money-making tips that will help you avoid steep fines and costly repairs.

"Spotting and fixing vehicle defects early on keeps you safe and your truck in good shape."

Why Following the CDL Pre-Inspection Checklist is So Important

The price of a failed DOT inspection makes completing a thorough CDL pre trip inspection checklist even more pressing. Violations can cost carriers thousands each year in both penalties and out-of-service (OOS) trucks. According to the FMCSA, around 20% of vehicles are OOS due to failed inspections at any given time. For an owner-operator, this means you'd be paying thousands in vehicle payments on a truck that's not earning you any money.

The pre trip checklist is designed to avoid any possible accidents due to equipment failure and failed safety inspections. A few minutes of caution pays for itself ten-fold down the line.

General Tips Throughout Your Pre-Trip Inspection

Because you don't have access to a pre trip inspection checklist during the CDL exam, drivers have created a few tricks to pass this part of the test. The most common memorization tricks are:

BBC: Is any plastic or metal bent, broken, or cracked?

CDL: No hard materials should be cracked, damaged or loose.

ABC: Are there any abrasions, bulges, or cuts on the rubber?

PFL: Peak for leaks in fluid and air containers.

PMS: Are bolts properly mounted and secure?

ABCDF: Do you see abrasions, bulges, cuts, dry rot, or frays?

A bit of common sense will help you put these acronyms to good use. For example, there's no way BBC would apply to rubber, as rubber wouldn't be bent, cracked, or broken. Most drivers pick one for each material type and stick with it until they get more comfortable with the list.

What are the ABCS in a pre-trip inspection?

As mentioned above, the ABCs refer to Abrasions, Bulges, and Cuts to check for during the Class A CDL pre-trip inspection. This applies to rubber or soft surfaces - things like tires, hoses, and rubber bushings.

How Long Should a Proper CDL Checklist & Inspection Take?

Ideally, it takes 15-30 minutes to run through the CDL pre trip inspection checklist depending on experience level and whether or not any issues are found. If issues are found, they must be fixed right then, before taking any more loads.

The cost of preventative maintenance averages $15,000 per truck per year. This figure is a drop in the bucket compared to the cost of inoperable equipment. Breakdowns and crashes due to mechanical failure cost carriers billions industry-wide. Consider an owner-op paying $3,500 per month on insurance and loan payments. Those payments still have to be made regardless of whether the truck is in the shop or on the road. Adds up quickly right? Spending a bit of extra time and money on prevention keeps trucks on the road and earning money.

Standard cdl pre trip inspection checklist.

Our pre-trip inspection Class A checklist serves two purposes: helping new drivers pass this portion of the CDL exam, and guiding CDL holders through the process with 100% accuracy every time.

A few exam tips before the pre-trip checklist:

• Point to or physically touch each area being inspected. This will help your memory and prove you know your stuff.
• Start with a big section and break it down into small sections from left to right like reading a book.
• During the test, make at least 2 checks for every item or area.

▢ Hoses: all hoses should be secured on both ends with no splits or cuts

▢ Fluids: engine oil, washer fluid, coolants, and power steering

▢ Belts: no more than 1/2"" to 3/4"" of give, securely mounted with no fraying ends

▢ Alternator: securely mounted, belt in good shape

▢ Water pump: properly mounted with no split or leaking hoses

▢ Air compressor: securely mounted, no visible or audible leaks

If Left Unchecked:

Oil leaks and coolant issues are two of the most common breakdown causes, both of which can be spotted during pre-trip. Scheduling dry maintenance every 10,000-25,000 miles and wet maintenance every 25,000-50,000 miles can prevent most engine issues. These regular services, ranging from $50-$450 , are nothing compared to the price of replacing or rebuilding an engine - $20,000 - $40,000 . Thorough pre-trip inspections are the best way to avoid engine breakdowns and escalated damage.

▢ Brake Pads: ¼ minimum brake pad thickness

▢ Slack Adjuster: 1” of play and at a 90' angle to the brake chamber

▢ Brake Chamber : no audible leaks or visible damage

▢ Brake Hose: securely mounted, no audible leaks, splits, or cuts

▢ Brake Drum: no bluing from excessive heat, securely mounted

Brake problems are the most common cause of semi-truck accidents . While over-breaking is a big player in this, a lack of maintenance and unnoticed airline damage usually play roles, too. 

Brake pad replacement costs $150-$300 per axle ($750-$1,500 total) and $80-$160 per hour in labor. The consequences of brake failure are incalculable - body repairs, cargo damage, and strikes to your carrier safety rating will follow you. The last thing you want to deal with is higher insurance premiums or trouble getting placed on loads. Take this part of your pre-trip inspection extra seriously.

• Front: clearance lights, headlights, high beams, turn signals, flashers
• Sides: turn signals, flashers, clearance lights
• Rear: tail lights, brake lights, left turn, right turn, 4-way flashers
• Front: clearance lights
• Rear: clearance lights, tail lights, license plate lights, brake lights, turn signals, flashers

▢ Reflector Tape: clear, free of dirt

If Left Unchecked:  

Fines for a headlight out vary from state to state, but the consequences of non-functioning brake lights or turn signals could confuse drivers and create unsafe situations. Both of these can be spotted and fixed during a pre-trip inspection. It's easy to run to the shop and change the light yourself if possible. License plate bulbs are just a few cents, and headlight kits range from $40-$250 . Don't add the price of a ticket on top from getting pulled over!

On the topic of lights, it's important to note that warning lights like the engine light or battery alert light should be addressed immediately to avoid developing into bigger issues down the road.

▢ Wheel inside: not broken, no illegal welds

▢ Wheel outside: no cracks or illegal welds

▢ Tires: no cuts or bulges, air gauge matches manufacturer recommendations, tread depth at least 4/32" and evenly worn

▢ Spacing: duals are properly spaced

▢ Valve Stem: not audibly leaking. metal cap in place and secure

▢ Lug Nuts: present, tight, no cracks

▢ Hub Seal: not cracked or loose

Tire problems cause 8,000 truck accidents per year. While flats are sometimes unpreventable, blowouts can be caused by improper inflation , which can also shorten the lifespan of your tires via irregular wear and tear. Timely alignments and rotations can also keep tires running longer; the price of new big rig tires is from $250 to $600 . A tire blowout mid-load can make you miss your appointment and waste precious driving hours - all the more reason to be thorough in your truck inspection.

Something to keep in mind is the way you conduct your pre-trip checklist is important. For example, there are a lot of videos and content showing truckers how to check their tires by kicking, beating, and even using a hammer. Hitting a tire with force like that, in the right spot (damaged) can lead to a blow-up and severely injure you and your truck. Even lugging around a damaged tire can lead to a blow-up . Stay safe and take all necessary precautions!

Steer Axle/Rear Suspension

▢ Steering Shaft: not BBC, securely mounted

▢ Steering Gear Box: not BBC, securely mounted, no visible leaks

▢ Hose: no visible leaks, properly mounted

▢ Pitman Arm: not BBC, securely mounted, nuts and pins are all hardware is present and secure

▢ Drag Link: rubber is in good shape, bushings are properly greased and not split or cut

▢ Upper/Lower Control Arms and Tie Rod: not BBC, securely mounted

▢ Spring Mounts: not BBC, securely mounted

▢ Leaf Springs:  not BBC, securely mounted, not shifted or scissored

▢ U-bolts: not BBC, securely mounted, all accounted for

▢ Shock Absorber: not BBC, securely mounted, no visible leaks, rubber bushings aren't dry rotting

If Left Unchecked: 

On their own, each of these parts isn't a huge deal to replace. For example, 

• Steering Shafts: $100-$300
• Pitman Arms: $50-$200
• Steering Gear Box: $150-750
• Shock Absorber: $50 - $90

On the other end of the spectrum, neglect can lead to the truck leaning to one side, which can cause further damage. Blown shock absorbers will also make your truck hard to handle, steer, and control. Say it takes a mechanic 3-5 days to diagnose and fix a suspension issue. You could lose out on $1,000 - $3,000 in earnings that week, plus the several hundred it will cost in repairs. Spotting these issues during your 15-minute pre-trip inspection could save you thousands.

▢ Mirrors: mirrors adjusted properly and without cracks, free of dirt

▢ Foot Pedals: unobstructed

▢ Horns: functioning properly

▢ Windshield: no stickers, cracks, or excessive dirt

▢ Heater/defrost: both operate when the fan is set to max

▢ Wipers: arms move properly when turned on, and wiper fluid works

▢ Steps: mounted and secured

▢ DEF cap: secured

▢ Fuel cap: gasket and vent in place, chain secures cap to the tank

▢ Skirting: no damage, panels secure

To be mid-trip and discover your defrost or wipers don't work can be a scary feeling. A suddenly obstructed view with no way to clear it is what the in cab inspection is meant to avoid.

With the average truck eating up $15,000 per year in maintenance and repairs, it's the little things that add up to such a steep number. For example, fixing a windshield can cost anywhere from $500 - $2,000, depending on the truck type and severity of damage. Wiper blades cost $14 - $35 on average, and an AC compressor would cost around $200 to fix/replace . It's easy to see how these numbers add up fast, but waiting until something breaks on the road and taking on the cost of an OOS violation can quickly double and even triple those numbers.

▢ Frame: no illegal welds, not BBC, no rust

▢ Drive Shaft: not BBC, properly mounted, not twisted, and the U-joints are clean

▢ Universal joint: not BBC

▢ Differential: no leaks

Rusting frames and chassis can be prevented and stopped in their tracks with preventative protective sprays . To protect a drive shaft, keep it free of dirt and debris and make sure it's well lubricated. The price of a new driveshaft is around $1,200 . The cost of checking it during pre-trip is free. Remember, the purpose of a pre trip inspection Class A is to not only keep you safe but to spot mechanical issues before they get worse.

▢ Bolts/Bracket: all accounted for and secure, not broken or bent

▢ Locking pins: all accounted for and secure, not broken or bent

▢ Release Handle: releases freely and is in the locked position.

▢ Apron: no cracks, no gap between apron and 5th wheel plate, securely fastened

▢ Skid Plate: no cracks, properly greased, securely mounted

▢ Platform: securely mounted, not cracked or broken, no illegal welds

▢ Kingpin/Locking Jaws: locking jaws are wrapped around kingpin, which is straight with no chips or welds

▢ Air Lines: securely mounted at both ends. Lines are free of cuts, no audible leaks.

▢ Electrical line: secured at both ends. Lines are free of cuts, no audible leaks.

The consequence of worn brackets or pins is accidental uncoupling, otherwise known as dropping a trailer. Not only can this cause accidents, but it can damage the trailer and the cargo inside. In these cases, the carrier is almost always liable for any damages.

▢ Header Board: properly mounted and secured, not BBC, no missing rivets

▢ Clearance lights: not loose, cracked, or dirty 

▢ Top rail: No cracks or collision damage.

▢ Rivets, holes: no holes, all rivets in place.

▢ Landing gear: properly mounted and secured, not BBC, shoes are present, handle moves freely

▢ DOT tape: covers at least 50%, not dirty or peeling

▢ Floor: no holes

▢ Cross members: none are damaged, missing, or twisting

▢ Tandem release: properly mounted and secured, not BBC

▢  Slide rail: properly mounted and secured, not BBC

▢  Pins: engaged

▢ Clearance lights: not cracked or dirty

▢ Doors: not broken, no holes, seal intact

▢ Hinges:   securely mounted, not BBC

▢ Door handles and rods: securely mounted, functioning properly

▢ Lights: securely mounted, not cracked or dirty

▢ DOT tape: clean, covers 100% of the backside of the trailer

▢ Bumper: properly secured, not BBC

The trailer keeps your precious cargo safe. Issues with the cross members, flooring, or doors leave cargo unsecured and exposed to the elements. Of this list, the most expensive fix is replacing or repairing cross members. Just one broken cross member puts a truck OOS, and repair/replacement costs thousands , mostly in labor. How can they get damaged?

• sloppy hooking/unhooking
• exposure to the elements
• uneven loading
• punctures from inside the trailer
• blown tires

If you notice trailer damage during your Class A pre-trip inspection, you'll have to get it fixed before taking any more loads.

▢ Air pressure: set to proper operating range, no warning lights

▢ Temperature gauge: rising to proper operating range, no warnings

▢ Oil pressure: rising to proper operating range (25-50 PSI), no warnings

▢ Voltmeter: operational, 13 - 14 volts

▢ Dashboard light indicators: check the indicators for the high beams, turn signals, and flashers.

▢ Fuel: gauge matches visual compared to looking in the tank

▢ Tachometer: 1000-1500

▢ Water temperature: 180-205 degrees

▢ Def level: minimum of one light bar

If these gauges don't pass the pre trip inspection Class A checklist, it's likely due to faulty wiring or a fuse issue. You'll have to identify the source or take it to someone who can.

Simple electrical fixes can be done on your own. At a mechanic, a blown fuse costs around $100 to repair, and a full rewiring can cost anywhere from $1,000 - $2,000 .

Preventative maintenance includes replacing old connections with more modern technology and having circuit protectors checked during regular maintenance.

A DVIR, or Driver's Daily Vehicle Inspection Report, is the form that drivers fill out during the Class A pre-trip inspection and at the end of their day. It's designed to keep the company informed of any missing or damaged parts of the truck, keep maintenance costs as low as possible, and keep trucks on the road safely.

Drivers should keep their completed forms accessible and stored for up to 6 months, just in case they're asked to pull them for reference.

Most Common Issues Found During Pre Trip Inspection

Below are the most common issues found while running through a CDL pre trip inspection checklist. If left unchecked, these things can lead to getting pulled over and receiving a violation, or worse, causing a breakdown where you or others are hurt. 

Here's a run-through of what to do if you run into these common issues and how to avoid them."

Broken Lights

What to Do:

The first of the three L's (lights, leaks, and leans), broken lights are an easy way to get pulled over and trigger a full-blown roadside inspection. If you notice an issue with one of the many lights during your truck inspection, you're required (and it's in your best interest) to get a replacement immediately.

How to Avoid This:

Obviously, there's no way to avoid lights going out. However, you can avoid faulty reflectors by getting regular washes, especially if you've driven somewhere rural or salted. Shippers appreciate a clean truck, too.

Maintenance as a Money Saver:

Lighting violations are known as ""gateway violations"" because they open the door to law enforcement noticing other things wrong with the truck. This makes staying on top of maintenance even more pressing. For example, most new reflectors cost around $5 each . If you get pulled over for missing or faulty reflectors, it could trigger an inspection that makes you A) sit still and waste hours, B) miss your appointments, C) end up OOS, and D) get in trouble with your company.

Leaning is the second of the three L's. A leaning truck could indicate

• tire problems
• faulty suspension
• worn spring bushings
• airbag issues

The first step is to check out the above mechanisms yourself for any noticeable worn springs or airbag problems. To avoid damaging any equipment even further, go to the shop after your pre-trip inspection and get it checked out.

Uneven loading puts excess strain on the truck and can cause leaning over time. You have every right to ask shippers to fix uneven or shoddy loading.

A new leaf spring is one common solution to fixing a leaning truck. Costing anywhere from $80 - $450 , it's a solid first step compared to full suspension repair which costs $1,000 - $2,000.

The last of the three L's are leaks. When you look on the ground near the engine, do you see any puddles or fluids? There are three common sources:

• power steering
• water leaks
• brake fluid

Identify the source. What type of liquid is it? Does it smell? How big is the puddle? Is the radiator cap secured and not broken? If you can identify the problem and fix it - great. If not, make a call to the nearest shop.

The reason you check every bolt and hose on the pre trip inspection Class A checklist is to avoid these mystery leaks. Preventative maintenance is key.

Maintenance as a Money Saver: 

It's a lot cheaper to replace nuts and bolts than it is to replace an entire system that's been damaged due to ongoing leaking. Driving with a leaking radiator can damage engine bay components and require repairs to a chain of other parts. If the problem was the radiator gasket, for example, the cost of a replacement would only be around $40 .

The limit for tread depth is 4/32" on steer tires and 2/32" on others to pass a Class A pre trip inspection. Sometimes tires look good during inspection, but after a long haul, treads have worn down too low. 

Tire replacement should be prompt - blowouts happen all the time and can do serious damage to the underside of the trailer. Check if the tire is still under warranty, and have it and any others replaced ASAP.

Make sure tires are always filled to the manufacturer's recommendation and ideally the same PSI in each tire. Note that tread loss accelerates in extreme heat. Tires gain about 1 pound of pressure every 10 degrees as the temperature increases. Asphalt can be 20-50 degrees hotter than the air; keep that in mind before thinking any bulges or worn tread will be fine.

New big rig tires cost $250 - $600 , or $0.04 per mile. Because of the high cost, many large fleets are opting for imported tires to keep costs down. Research reviews on the brand you have in mind first - many have bad reviews from truckers. Here's a video that shows how much time can be lost by blowing a steer tire.

Overheating

Pull over safely and legally. Give the truck some time to cool down in idle. Try turning the heat on to get some of that heat out of the engine - it will feel uncomfortable but protecting the engine is worth it. Check to see if the radiator is jammed with debris or has bent fins. An overheating truck could be difficult to diagnose, and you'll most likely have to have a mobile mechanic come to you. If you were going up a steep grade, it might have just been the way you were driving.

• Keep the radiator clean
• Check the muffler for soot build-up in older trucks
• Don't use cruise control in hilly areas
• Don't overload the trailer

Constant overheating can be hard to diagnose, and it can make you chronically late to appointments. Regular maintenance and a thorough CDL pre trip inspection Class A are where the little details can be spotted and nipped in the bud.

Bypass Construction

The DOT 511 traffic app provides state-specific traffic and construction updates. Check for delays on your route to get ahead of detours and lane closures. Each state has their own app, so download it ahead of time.

Why does it matter? If you earn $0.60 per mile on a 400-mile trip, that's $240 earned in roughly 8 hours. Now, say traffic adds 1.5 hours to your trip. You still earn the same $240 AND you don't have the opportunity to pick up another load before you reset. Time is money!"

In 2016, truckers were delayed a total of 1.2 billion hours because of congestion on the road - that's in the billions! Truck bottlenecks are mostly common in major cities. Planning your route ahead of time to avoid traffic delays is crucial to your bottom line.

Weather Apps

Winter and summer storms can eat into income and create seriously dangerous roads. Depending on the weather, you might be able to plan a different route to avoid delays or change the time and place you stop to rest. The AccuWeather app is a popular choice among drivers. 

The horror stories of drivers getting stuck at a rest stop for days or getting blown over by strong winds paint the ugly picture of the weather as a driver's biggest opponent.

Truck Parking

After finishing your Class A CDL pre trip inspection, take a few minutes to map out overnight parking spots along your route. American Truck Parking does a good job of showing truck stops and rest areas that offer overnight parking, as well as the pricing, pictures, and other amenities. You can filter out for gated parking spots, CAT scales, showers, truck washes, and much more. Compare pricing beforehand and save yourself the cash!

Speaking of cash, it's important to take advantage of freight factoring. This method can offer truckers immediate cash flow, while waiting on customers to pay.

In addition to managing your cash flow, be sure to consider freight insurance , this protects your trucks and cargo from any potential risk during transit.

Dock Details

Headed to a new shed? Check them out on Dock 411 to confirm things like pallet restrictions and hours of operation. Not sure if you can fit? Most places have pictures that other drivers took or reviews about slow loading and yard hazards.

The benefit? This helps plan things like getting lunch, calculating hours, and knowing whether or not you even want to take a certain load. If you see reviews that a shed has an average 7-hour loading time (the standard is 2.5 hours ), you can have a conversation with dispatch early on to make a game plan regarding detention and/or layovers.

While researching docks, don't put your well-being on the back-burner. Be sure to invest in the right truck mattress for a good night's sleep during layovers or breaks.

Gas Buddy helps truckers find the cheapest gas prices along their route. While you're looking, you can see what stops have showers, food, repairmen, and other amenities so you can save time at a 1-stop shop.

For reference, the average owner-operator spends $45,605 on fuel per year ( 2022 ). Company drivers don't usually have this problem since they have discounted fuel cards. (You can get fuel cards with Cota Systems , too). To learn more, check out our post on the best fuel cards for truckers.

Legally Bypass Inspection Sites

Did we mention that time is money? Another way to save time is with Drivewyze , an in-cab app for driver devices that provides inspection bypass opportunities at 884 weigh stations across the states. When bypass isn't allowed, they have an e-inspection system that speeds up the process and avoids long lines. It sounds too good to be true, but it's 100% legal and works 89% of the time. Prepass is another company that offers this service.

Weigh station stops can take anywhere from 30 minutes to a few hours if lines are long or they find something wrong with your truck. That 30-minute stop could have earned you $15 (at $0.60/mile for 25 miles). Doing so every day could cost you $300/month, and that's IF the stops only take 30 minutes!

Most drivers use a combination of navigation apps. Hammer and Google Maps are popular choices. Systems made specifically for truckers won't take you down prohibited roads - that's why Google Maps alone might not cut it.

Health Apps

Recent studies found that workers who take care of their mental health average 9.3 fewer sick days per year than workers who don't. The life expectancy of truck drivers is 61 years , partly due to their unhealthy lifestyle and work-related stress. Your health is just as important as any CDL pre-trip list. Obesity is one of the most prevalent health issues in the trucking industry for long-haul drivers. These healthy habits can save you down the line:

• Skip the fast food, sugary snacks, and sodas.
• Find a way to manage your stress. Talking to a friend while you drive or finding a podcast that you enjoy are two common solutions.
• Exercise during home days focusing on your back.
• Switch up your stimulants. Instead of Redbull every day, try green tea, coffee, or Yerba Mate a few days per week.

Try out some apps like MyFitnessPal for weight loss and nutrient tracking or Luminosity for mental health support.

OTR drivers can take advantage of toll services like Prepass (which also serves as a weigh station bypass) and Best Pass , a prepaid transponder system. If a toll company isn't covered, it's best to just use cash and keep your receipt. A few tips:

• Take a second to review toll prices on your trip. Any tolls should be factored in when dispatch discusses rates, especially in cities.
• Find and join any toll discount program you can find (take the New York toll reimbursement program, for example)
• Best Pass offers cash toll discounts, but you should verify that the transponder rate wouldn't have been the same (and much faster).

How to Remember Pre Trip Inspection CDL Checklist

Start with our printable CDL pre trip inspection cheat sheet and repeat, repeat, repeat. Use the same checklist every time so your brain can get into that rhythm. Remember the acronyms:

BBC: Bent, broken, or cracked

ABC: Abrasions, bruises, cuts

PFL: Peak for leaks

3 L's: Lights, leaks, leans

Understanding the mechanics of the truck and how everything works together will help your brain form stronger connections and remember more. Try explaining the process to your wife, kids, or friends (even if they won't remember) so you can spot areas you need to study the CDL pre trip inspection PDF more.

What is the item most commonly overlooked during a pre trip inspection?

A few items on the CDL pre trip inspection checklist trip up new drivers most often:

• Chocks: During your CDL class a pre trip inspection, you'll have the vehicle on and off, and be testing various brake systems. Chocks prevent the truck from moving around while you're underneath and walking around.
• Seatbelts: It's often the last thing on a new driver's mind on the long list of items to inspect. But, your life depends on it.
• Emergency Kit: Especially if you drive a shared truck, you don't know if the previous driver used up anything in the kit. Just because you see the kit doesn't mean everything is present and functional.
• Reflectors: Reflectors help other vehicles see you at night. Because there are so many, drivers rush through this check or give them a quick glance. These are another "gateway violation" that can get you pulled over and given a roadside inspection.
• Wheel Lug Nuts: Loose wheel fasteners could have your tires speeding down the freeway toward other cars and trucks. Double-check that all lug nuts are fastened and free of rust.
• Personal Health: Remember the figures we mentioned about truck driver life expectancy. Put your health first, and don't drive if you feel sick and feverish.

This is all about the safety of you and others. Keep your pre trip inspection Class A cheat sheet with you and go through the same, thorough motions every time.

CDL Class B Pre Trip Inspection

The CDL Class B pre trip inspection follows virtually the same guidelines as Class A, but they differ in terms of vehicle type. 

Class B includes buses, straight trucks, and smaller commercial vehicles that are typically not designed to tow additional trailers. Items like the 5th wheel and coupling mechanisms are obviously left off. Drivers have to check passenger doors, wheelchair lifts, handrails, emergency exits, and seating for passenger safety.

New Truck Pre-Inspection Checklist Addition

Non owner-operators who are regularly assigned new trucks can't take for granted that everything was left as you might have left it. Add these to your pre-inspection checklist:

• Cab card & book: permits, registration, IFTA paperwork, and cab cards are present and up-to-date
• IFTA Sticker: current year is displayed on both sides of the truck
• Elog Device: present and functional
• Permits: in the cab card book and up to date
• License Plate: front and back plates match
• Medical Card: med card and CDL are on your person or in the truck
• Paper Logbook: backup if E-log stops working
• Inspection sticker: stuck to the side of the truck and up-to-date
• FMCSA Safety Book: within arms reach of the driver's seat

Additional Supplies: load securing equipment, extra coolant and oil, cable cutters, hammer and wrench, hard hat, and steel-toed boots, and any wisdom you've gained from recent semi truck shows for the latest in safety and efficiency enhancements.

Final Notes on Completing Your CDL Pre-Trip Inspection Checklist

So, you're armed with the ultimate CDL pre trip inspection checklist that will help you pass your exam and save on vehicle maintenance. Your truck is your money maker; our goal for this guide is to give drivers the tools to protect their biggest asset and keep the most money in their pockets as they can. That includes showing you the best truck driver accessories and the best trucking GPS , so you'll be set for the long-haul.

Air Brake Test

There are three stages to an air brake test:

• Applied Pressure Test – When doing the Applied Pressure Test, you want to build the air pressure to governor cut out. Put the truck in the lowest gear, turn the engine off and immediately turn it back on. Push in the tractor and trailer valves which then release the parking brakes. Push and hold the brake pedal, allowing the gauges to stabilize. When the gauges have stabilized, announce the Primary and Secondary PSI. Listen for air leaks while doing this.
• Warning Light and Buzzer – Pump down on the brake pedal until the warning light and buzzer comes on. This is typically at or before 60 PSI.
• Tractor/Trailer Protection Valve Pop Out – Pump down on the brake pedal until the tractor and trailer protection valves pop out, this will be between 20 and 40 PSI.

Air Pressure Gauges

The air pressure gauges build to governor cut out.

Emergency Equipment

Truck has a fire extinguisher, three red reflective triangles, and spare electrical fuses.

Heater and Defroster

Demonstrate both the heater and defroster are working properly.

Horns (Air Horn and City Horn)

Blow both horns to make sure they are working.

Lighting Indicators

Check the left turn, right turn, four way flashers and high beams; also point these out on the dashboard.

With the transmission in neutral, fully depress the clutch. Turn the key on, check the ABS light, announce when it comes on and off, and start the engine.

The seat belt is not ripped or frayed and adjusts and latches properly.

Oil Pressure Gauge

The engine oil pressure gauge should rise to normal operating range.

Parking Brake

• Trailer Parking Brakes – Set the trailer brake, release the tractor brake, and tug lightly on the trailer.
• Tractor Parking Brakes – Set the tractor brake, release the trailer brake, and tug lightly on the trailer.

Service Brake Check

Release both the tractor and trailer brakes. Drive at idle speed. Apply the service brake to make sure you come to a complete stop and that it doesn’t pull to the left or right when applying the brakes.

The voltmeter is charging between 13 and 14 volts.

Water Temperature Gauge

The water temperature gauge rises to normal operating range.

Windshield and Mirrors

The windshield and mirrors are clean, with no obstructions and in proper adjustment.

Windshield Wipers and Washers

Demonstrate the wipers and washers are working properly by spraying the windshield.

This is a really nice complete list, very useful.

Class A CDL Pre-Trip Inspection Checklist & Guide

Before heading out on a route, it’s extremely important that you inspect your truck. This is not only a requirement but also essential in keeping you and others safe on the road. If you’re in the process of studying for your CDL exam, you’re probably trying to figure out how to remember all the pre-trip inspection items and wondering how you’ll check all those items before every trip. Fear not! While memorizing these inspection items is necessary for the test, your pre-trip inspection will likely be a little bit shorter on a daily basis.

Not sure what is essential to look at during your CDL pre-trip inspection ? Check out our CDL pre-trip inspection checklist below for a concise list of the main items you’ll need to look at before every trip. This list is not exhaustive though, so be sure to add anything that may be specific to your truck.

CDL Pre-Trip Inspection List

While the DOT isn’t explicit with which items drivers are required to inspect during their pre-trip inspection, it is important to take a look at the following items:

• Service brakes, including trailer brake connections
• Parking (hand) brake
• Steering mechanism
• Lighting devices and reflectors
• Windshield wipers
• Rear-vision mirrors
• Coupling devices
• Wheels and rims
• Emergency equipment

Your company may have additional requirements, but the items listed above are all necessary to include in your daily vehicle inspection report (DVIR). Your DVIR should be completed post-trip, but it’s beneficial to review all list items prior to setting off on your trip as well.

When completing a Class A CDL pre-trip inspection , here is a more detailed list of items that you should check. Again, it’s important to note that these are not the only items you should be checking – this is just a good starting point.

Under the Hood

• Fluid Levels (including oil, coolant, and windshield washer fluid)
• Fluid Leaks
• Damage to Hoses and Belts
• Damage to Wiring
• Steering Shaft

Pre-Trip Inspection Checklist for Truckers

July 28, 2023.

Table of Contents

The most important element of a truck driver’s daily routine is the pre-trip inspection. Pairing a comprehensive pre-trip inspection with a regular preventative truck maintenance schedule is key to ensuring your safety and the safety of others on the road . To give you an idea of how essential the pre-trip inspection is, consider that drivers are required by law to record at least one inspection per day.

Finding and fixing mechanical defects early is essential to functioning as a safe operator.

What is a Pre-trip Inspection?

The pre-trip inspection is the process of thoroughly examining the truck before starting a new journey. It ensures the safety of the driver and the others sharing the road with them by identifying and addressing mechanical issues early on, so truckers can prevent unexpected breakdowns, delays, and potential accidents. 

Drivers must record at least one pre-trip inspection per day. Learning the process is crucial for obtaining a commercial driver's license (CDL) and continuing a successful career in the industry. 

Benefits of a Truck Pre-Trip Inspection

Aside from being a requirement, here are some benefits of conducting a thorough pre-trip inspection:

• Safety is prioritized by the early identification of potential mechanical issues, ensuring a secure journey for truck drivers and others on the road.
• Early detection and resolution of mechanical problems during this essential routine lead to reduced delays and costly repairs.
• Regulatory compliance is showcased as pre-trip inspections are a legal requirement, reflecting professionalism and commitment to safety.
• Smooth schedules are maintained as pre-trip inspections help prevent unexpected breakdowns and disruptions.
• Early issue identification and timely repairs achieve cost savings and prolonged vehicle lifespan.
• Improved fuel efficiency results from ensuring components like tires and engines are in top condition.
• Trust and professionalism are earned by conducting regular inspections, leaving a positive impression on clients, employers, and regulators.
• Reduced on-road accidents are promoted by verifying lights and brakes are in optimal condition.
• Boosted driver confidence is achieved by confirming the truck's peak condition, enabling worry-free journeys.

This powerful routine keeps us safe, compliant, and efficient on our trucking journey.

15-minute Pre-trip Inspection Checklist

A properly conducted pre-trip inspection is a core proficiency evaluated during the CDL exam. The most efficient way to prepare for the pre-trip inspection exam is to use a checklist. Practice using the checklist several times a day until you have the process memorized and have mastered this important truck driver skill . It will serve you well in helping you obtain your CDL and will continue to benefit you throughout your career.

It may seem overwhelming and difficult at first , but with practice, the pre-trip inspection will become a habit. To help you, we’ve prepared this pre-trip inspection guide.

A good starting point is the FMCSA and its regulations concerning the pre-trip inspection. Different companies have produced their pre-trip inspection checklists, so it’s a good idea to consult your company’s guidance and compare it with the FMCSA regulations to ensure you are conducting a compliant inspection. 

Some common elements you will encounter on most checklists include:

1. Tire Inspection

Every 10 ° F change in air temperature can make vehicle, truck, and light truck tires lose one psi pressure. A tire with low pressure has a negative effect on the distance needed to stop and miles per gallon of gas.

Ensure no foreign objects are between the wheels and no space between tires and rims. Evaluate the tires for sufficient tread depth and look for cuts, bubbles, or gouges. 

Insufficient treads increase the likelihood of losing control from hydroplaning or sliding on standing water, snow, or ice. This is an especially important detail when preparing to drive your truck in winter weather conditions.

2. Lights and Reflectors Check

Verify the proper functioning of exterior lights, turn signals, warning lights, and clean lenses for maximum visibility. Ensure reflectors are free of dirt or debris and intact without cracks or missing pieces.

3. Brake Examination

Assess the brake system both inside the cab and externally. Verify proper brake adjustment with the slack adjuster, inspect brake linings for the appropriate thickness, and ensure air lines are free from damage, leaks, and properly sealed. This includes checking air brakes, parking brakes, and hydraulic braking systems.

4. Engine Inspection

Check the engine compartment for various components, such as the radiator, air compressor, steering gearbox, water pump, belts, hoses, and wiring.

5. Fuel Tank and Battery Check

Visually examine the fuel tank and battery area to ensure no cracks or leaks. Verify the battery levels for sufficient power and proper charging.

6. Fluid Inspection

Inspect fluids under the truck for signs of leaks, including fuel, oil, coolant, power steering fluid, brake fluid, and windshield washer fluid. Check fluid levels and assess the condition of hoses, belts, and wires for safe operation. Pay special attention to the oil pressure gauge for proper functionality.

7. Windshield 

Chipped, cracked, or deteriorated glass weakens the final barrier that prevents the driver from being thrown during an accident and can inhibit clear road visibility. Also worn-out wipers will reduce visibility when driving in the rain or snow.

8. Emergency Kit

Road flares, triangles, and a fire extinguisher are the emergency equipment necessary to safeguard the vehicle and the driver should an accident or breakdown occur and must not be missing or broken. The fire extinguisher must be easily accessible, with a current inspection, and maintain the appropriate PSI. 

9. Mirrors with Swivel Mounts

Frozen or loose mirrors prevent the driver from properly adjusting them to cover blind spots. It can create a greater risk of hitting the side or colliding when turning.

10. Coupling System Assessment

Examine the coupling system, paying close attention to the kingpin and sliding fifth wheel locking pin. Check the condition of air lines, apron, electrical connections, gap, glad hands, locking jaws, mounting bolt, platform, release arm, and a skid plate that connects the trailer to the cab.

11. Cabin InspectionTemperature

Inside the cabin, check the seat belts for wear or fray and ensure a snug fit. Assess the operation and functionality of inside and outside mirrors, seat position, steering wheel, pedals, windshield, wipers, horns, lights, and gauges. Make sure all alerting systems, including ABS lights, are working correctly.

Verify the temperature, controls that are not working properly can produce physical stress, fatigue, and distraction while driving.

12. Trailer Examination

Conduct a thorough inspection of the trailer for mechanical defects that might hinder secure mounting to the tractor. Look for holes, cracks, breaks, bends, or missing rivets in the headboard, frame, release pins, cross members, release handles, locking pins, doors, and hinges.

13. Back of the Truck Inspection

Before hooking up to a trailer, check the back of the truck for properly inflated tires with decent tread, undamaged brake chambers, intact shocks and airbags, a clean driveshaft without debris in the u-joints, a sturdy and unbroken frame, well-greased fifth wheel, and leak-free fuel tanks. Also, inspect stairs and catwalks for cleanliness and integrity.

A thorough pre-trip inspection should take approximately 15 to 30 minutes to complete.

How to Properly Report a Pre-trip Inspection?

‍ According to current guidelines by the FMCSA , at least one inspection must be logged in your hours of service each day. Previously, drivers were also required to fill out a pre-trip inspection report each day. However, recent changes in the guidelines now only require you to fill out an inspection report for the purpose of recording a defect found during your inspection. If you have uncovered no defects, you are no longer required to fill out the inspection report. 

Companies such as JJ Keller produce market inspection reports that you can keep on board your truck in the event you need to fill one out. Additionally, you can, in a pinch, use these reports as a checklist if you are still unfamiliar with the pre-trip inspection process. 

Regardless of how long you’ve been working as a truck driver or how many other trucker safety tips you follow, the pre-trip inspection will serve you well to keep you safe as you go about your day. Discovering critical defects early can be the difference between making it to your next stop and ending up broken down on the side of the road , or even worse, involved in a preventable accident.

Complete CDL Pre-Trip Inspection Checklists for Class A and Class B Drivers

Your fleet is loaded, and the fuel tanks are full – you’re ready to move. Or are you?

If you haven’t completed a pre-trip inspection checklist, you might not be.

The Department of Transportation (DOT) requires all drivers holding a commercial driver’s license (CDL) to complete a pre-trip DOT inspection checklist before operating a commercial vehicle. Usually taking about 10-15 minutes, this inspection checks essential systems such as brakes and steering, as well as tires, mirrors, and emergency equipment.

So how can drivers know what to check? In this article, we’ll run down the DOT requirements for pre-trip inspection checklists, along with key differences between Class A and Class B inspections and even some useful tools that can help make the job easier.

What is a pre-trip inspection checklist?

A pre-trip inspection checklist is a list of items that CDL holders need to review before operating their vehicles. As you may have guessed, this process is known as a pre-trip inspection .

What is a pre-trip inspection?

Pre-trip inspections aren’t just an annoying routine – they’re an important and necessary safety measure that helps ensure that commercial vehicles are up to fleet safety operation standards .

While the scope and contents of a pre-trip inspection checklist vary according to the type of commercial vehicle and its use, you can complete most inspections in about 10-15 minutes. Checklist items generally include assessing the operational condition of anything the driver and vehicle need to operate the vehicle safely . This usually includes things like an air brake check, along with checking lights, tire pressure, couplings, and so on.

Drivers must also record their inspection results in a driver vehicle inspection report (DVIR), which is usually automated (or at least streamlined) in companies with established fleet management tools. Periodic inspection requirements require additional pre-trip inspections every 24 hours of continuous use or whenever the driver changes vehicles.

It may seem like a lot to review, but most of it boils down to common sense. Before you start crawling under the nearest truck, however, you may want to see whether you have to perform a pre-trip inspection in the first place!

Who needs to complete a pre-trip inspection?

Pre-trip inspections are mandatory for both Class A and Class B commercial driver’s license (CDL) holders.

If you’re a CDL holder, you probably already know which Class you fall into. But just in case, here’s a quick refresher on the types and weights of vehicles that different classes of CDL holders can operate.

• The Class A CDL applies to commercial vehicles weighing at least 26,001 pounds that can tow at least 10,000 pounds. This usually encompasses most towing commercial vehicles such as big rigs, tractor-trailers , and flatbeds.
• The Class B CDL applies to commercial vehicles weighing at least 26,001 pounds that can tow no more than 10,000 pounds. This usually encompasses most non-towing commercial vehicles, such as passenger buses, garbage trucks, and delivery trucks.

While there is also a Class C CDL, this usually extends to specialty vehicles not found under either Class A or Class B (such as hazardous waste transport). However, since their detailed inspection procedures are highly specific and beyond the scope of this article, we won’t cover them here.

But what’s involved in Class A and Class B inspections, and how can they differ?

Class A vs. Class B pre-trip inspections

While Class A and Class B vehicles share many of the same detailed inspection procedures (every commercial vehicle has brake lights, after all), each class and vehicle type has its own inspection procedures.

• Class A and Class B commercial vehicles share many common inspection items, such as front and rear suspension, brake lights, minimum brake pad thickness, oil level, etc. These are usually items that apply to any type of road vehicle.
• Class A inspection items are usually those related to towing systems in commercial vehicles, such as the trailer parking brake, coupling areas, etc. These inspection standards usually extend to the trailer, flatbed, or any other object that the truck is towing.
• Class B inspection items are usually those related to non-towing commercial vehicles. As this is a very broad category, some Class B vehicles may not require any additional inspections, while others may have several specific systems to inspect. In the case of the latter, these are usually items specific to the vehicle itself, such as checking for broken seat frames in passenger areas of a bus.

Of course, there’s much more to each pre-trip vehicle inspection than the handful of key differences we’ve listed here. In the next section, we’ll run down the pre-trip inspection process that applies to nearly every commercial vehicle and then detail more class-specific motor vehicle safety inspections.

CDL pre-trip inspection checklist

The standard CDL pre-trip DOT inspection checklist includes everything a commercial motor vehicle needs to navigate the road safely.

These are generally suspension- and engine-related items that would just as well apply to a regular car. As a general rule, a commercial pre-trip inspection test almost always includes the following motor vehicle safety inspections.

Brake system

There’s nothing more important than your vehicle’s air brakes. Note that the following air brake tests apply to both tractor brakes and trailer brakes on Class A commercial vehicles.

• Brake linings and brake pads: Brake pads should be no less than the minimum thickness of one-quarter inch (¼”). Also, be sure to check linings for oil and debris.
• Brake chamber: The brake chamber should be completely sealed with no audible air leaks.
• Air brake hose: No air should leak from the brake hose, and the line should be properly mounted and free of cuts or splits.
• Brake drum: Should not be blue from excessive heat.
• Hand brake: Push rods should have no more than one inch (1”) of play in either direction and stand up 90 degrees when pulled.

Depending on the vehicle, these items are usually checked with a 9-step, 7-step, or 5-step brake test. These tests usually involve pressing the brake pedal, service brake, hand brake, or foot brake under various conditions and seeing whether air pressure recovers to the proper level in time (see your vehicle’s operating guide).

For example, drivers can check for low air pressure by pressing the brake pedal to fan off the pressure. If repeatedly pressing the brake pedal results in a low pressure buzzer or light indicator, the brake system will require repair.

Engine compartment

Engine compartment inspection items include:

• Fluids: The coolant hose, power steering hose, and any tanks or reservoirs should all be securely mounted and have no leaks. Similarly, a dipstick should indicate that all fluid levels (including oil level and coolant level) are at their proper levels.
• Belts: All belts for compressors, pumps, and alternators should have no cracks or frays and give no more than one-half of an inch (½”) of play.
• Air compressor: Should be securely mounted and functional with no cracks or leaks.
• Water pump: Pump hoses must be properly connected with no leaks.
• Alternator: Wires and belts must be properly connected.

Front of vehicle

Front-of-vehicle inspection items usually include steering equipment such as:

• Steering column or steering shaft: The steering column should be straight and unbroken.
• Steering box: The steering gearbox should be intact, and all connected hoses should be securely mounted with no power steering fluid leaks.
• Tie rod and control arms: Both should be straight.
• Drag link: The rubber should be greased and uncracked.
• Pitman arm: All cotter pins and caste nuts are present, secure, and tight.

Front suspension

Front suspension inspection items include springs, spring mounts, shocks, and suspension airbags.

• Spring mounts and spring hangers: Spring mounts should hold spring hangers securely in place with no signs of wear, cracks, or breakage.
• Leaf springs: Should be secured to hangers with no cracks or breakage.
• Shock absorbers: Should have no leaks, splits, or dry rot in the rubber. Leaks are typically located where the top and bottom pieces overlap.
• U-bolts: Should all be securely fastened around the spring and axle.

Rear of vehicle

The rear of tractor or truck inspection items include the following.

• Driveshaft: Should be straight with unbroken U-joints.
• Exhaust: Should be free of rust with no leaks or excessive soot.
• Frame: Structurally sound with no damages or unauthorized repairs/welds.
• Steps: Structurally sound and mounted properly.
• Mud Flaps: Should be clean, unbroken, and secured at the right height.

Wheels and tires

Wheel and tire inspections check for both proper inflation and overall tire condition, specifically tread depth. Note that this also extends to trailers on Class A vehicles.

• Drive and steer tires: Tire tread should be even with a minimum tread depth of 2/32” on drive tires and a minimum tread depth of 4/32” on steering axle tires. Use an air pressure gauge to check inflation levels against manufacturer inflation levels. Treads and sidewalls should be free of cracks, bulges, and abrasions.
• Wheel rims: No unauthorized repairs or illegal welds.
• Hub seal and axle seals: Should show the axle and hub seal intact with no visible leaks or play.
• Dual spacing: Any dual tires must have enough spacing between them.
• Lug bolt holes: All lug bolt holes should have all lug bolts and lug nuts.
• Valve stem: No audible air leaks.

Lights and reflectors

Light and reflector inspections include everything from running lights to DOT tape and 4-way emergency flashers.

• High and low beams: Ensure both are functional on all forward lights.
• Turn signals: Make sure all are functional for both tractor and trailer.
• Brake lights: Make sure all are functional for both tractor and trailer.
• Running lights and license plate lights: Walk around the truck and make sure all are on.
• 4-way emergency flasher function: Walk around the truck to make sure the 4-way flasher rear and front lights are fully operational.
• Reflector tape and DOT tape: All DOT tape and reflector tape should be clean with no signs of excessive wear.

Driver door and fuel tanks

Cab doors and fuel tanks are often located in the same area on commercial vehicles. Be sure to check the following:

• Door and door hinges: Should be intact and latch completely. The rubber door seal should be clean and uncracked.
• External mirrors and mirror brackets: All external mirrors should be firmly attached to their mirror brackets. External mirrors should also be clean and uncracked. Also, be sure to adjust external mirrors and mirror brackets to provide an adequate rear view.
• Steps: Should be securely mounted and able to support the weight.
• Fuel tank: No leaks, with cap and seal unbroken and intact.

In-cab items

Cab inspection usually covers the following items:

• Steering wheel: Fully attached to steering column.
• Gauges: Check that air gauges, oil pressure gauges, and any other gauges for operation function normally within their operating range. Air pressure gauges should build pressure to the governor cut out during an applied pressure test.
• Warning lights: Lights should show clearly for any lighting indicators, such as ABS lights or oil pressure indicators.
• Windshield: Cracks beyond one inch (1”) are not permitted. Windshield wipers should be clean and work properly, and the truck should have enough windshield washer fluid.
• Seat belt: Should fasten securely.
• City horn and air horns: Both air and city horn should sound properly.
• Heater and defroster: Should heat and function properly.

Special checks for Class A and Class B inspections

As we mentioned earlier, a Class A pre-trip truck inspection will usually have different periodic inspection requirements than, say, a Class B pre-trip school bus inspection.

While periodic inspection requirements ultimately come down to the exact type of vehicle (a Class B garbage truck, for example, may require additional inspections for its armature and compactor), the main differences usually come down to trailers vs. passenger areas .

• Trailers share many of the same inspection checklist items as the tractor, specifically the wheels and tires, suspension, and rear of trailer lights and reflectors. Also, make sure that the landing gear is not broken and can be fully raised.
• Coupling area inspections include checking air connectors, electrical lines, and nearby glad hands. All mounting equipment, such as the fifth-wheel plate, kingpin, mounting bolts, skid plate, release arm, and locking jaw and pins, should be present, secure, and in good condition.
• Rear of truck suspension inspections share many of the same items as those of front inspections but with special attention paid to the torque arm (or radius rod), which should be mounted securely with intact brushings.
• Passenger items such as seating, passenger doors, and any wheelchair lifts should all be secure and in working order. Emergency exits should also be clearly labeled and sound an alarm when opened.
• School bus items include all of the passenger items listed above, with the addition of checking student loading lights, stop arm, student rear-view mirror, and a recent first aid and body fluid cleanup kit.

CDL pre-trip inspection checklist.

A commercial driver’s license (CDL) can put you behind the wheel of a tractor-trailer, a flatbed, or a tanker, among other non-passenger vehicles. Before you hit the road though, you’ll need to complete a CDL pre-trip inspection checklist. By inspecting the commercial vehicle beforehand, you can head out on your route knowing you’ve confirmed major systems and parts are road ready. Recognizing road safety is always a fleet priority . This article provides a comprehensive guide to the CDL pre-trip inspection checklist.

What is a CDL pre-trip inspection checklist?

A CDL pre-trip inspection checklist systemizes the driver’s vehicle inspection to ensure care and consistency. While a pre-trip inspection would be a best practice no matter what, the Federal Motor Carrier Safety Administration (FMCSA) requires these checks for commercial vehicles. Part 396.3 (a) calls on every motor carrier to “systematically inspect, repair, and maintain, or cause to be systematically inspected, repaired, and maintained, all motor vehicles subject to its control.” 

The fleet also has to keep formal records of their vehicle checks. So, drivers typically follow a CDL pre-trip checklist and record their findings in the driver vehicle inspection report, or DVIR , confirming the commercial motor vehicle (CMV) inspection is complete.

A CDL A pre-trip inspection checklist requires drivers to inspect many different parts and system including:

• Vehicle lights
• Tires, wheels, and rims
• Windshield wipers
• Emergency equipment

Different motor carriers may add their own expectations to the CDL pre-trip checklist. But they would be adding particular items to check, not doing away with the pre-trip inspection. After all, non-compliance with the federal pre-trip inspection requirements can earn hefty fines and lead to the loss of certifications and licenses.

The Class A CDL pre-trip inspection checklist is important enough that drivers testing for their license are expected to do the pre-trip inspection as part of their examination. Inspection requirements can vary by state. There’s also a Class B CDL pre-trip inspection list. 

Why is the CDL pre-trip inspection checklist important?

Compliance isn’t the only reason following the CDL pre-trip inspection checklist is important. The federal requirement is in place, after all, to ensure commercial vehicles on the road are safe to drive. 

With continued investment into critical infrastructure over the last 20 years, the percentage of roads in good condition has climbed since 2000. Yet the United States still has hazardous roads. In fact, “from 2000 to 2020, the share of major roadways in poor condition has remained fairly steady, rising from 11.8% to 13.8% over the course of 20 years.”

This makes keeping commercial vehicles in top shape all the more important to safety and efficiency. A CDL pre-trip checklist helps improve fleet safety by avoiding drivers going out on the road in vehicles that are not fit for duty. Taking a truck out on the road with an unsecured load, damaged brakes, disconnected wiring, or another issue could lead to drivers hurting themselves or somebody else.

Fleet vehicle inspections can also help keep drivers on the road. Identifying issues in advance can help avoid major problems that mean downtime and costly repairs. Plus, if the Department of Transportation (DOT) inspects the vehicle and finds something that the driver missed, they can put that vehicle out of service for longer. DOT violations can also lead to fines and hurt your CSA scores . A decrease in your CSA scores can lose your fleet business and cause your insurance premiums to go up too.

How to perform a CDL pre-trip inspection 

Although there is no specific time limit, a thorough CDL pre-trip inspection usually takes 15 to 30 minutes. This pre-trip starts at the front of the truck, but you can take the steps in this CDL pre-trip checklist and make them your own.

Front of the truck

Verify lights are clean, securely mounted, the right color, and working. Make sure the truck isn’t leaning. Confirm there are no leaks under the engine compartment.

Engine compartment

Check critical fluid levels. This includes power steering, coolant, windshield washer fluid, and engine oil. Inspect reservoirs, tanks, and hoses for any leaks, splits, or cuts. Ensure the hoses for the water pump, coolant, oil, and power steering are all properly connected and securely mounted. Check the air compressor is well secured. Inspect to make sure the belts on the alternator, pumps, and compressor are secure as well. They should have no more than 1/2″ to 3/4″ of play with no cuts or splits.

Front of the truck/tractor

Inspect the steering shaft and gear box to see they’re properly mounted to the frame and that there are no cracks or breaks. Check gear box hoses for leaks. Look for excessive play in the steering belt, secure connections. Check connections and look for leaks on pitman arm, drag link, and upper/lower control arms and tie rod. Move on to the spring mounts, leaf springs, and U-bolts to confirm they are not cracked or broken and are securely mounted. Do the same with shock absorber but also look for visible leaks and ensure the rubber bushings don’t have dry rot. Check the rubber of the airbag.

Check the hose, chamber, drum, pads and slack adjuster to confirm secure mountings and no leaks. Look out also for any breaks, splits, or cuts. Verify slack adjuster push rod has no more than 1″ of play and is at a 90° angle to the brake chamber. Check the brake drum has no bluing from excessive heat. Ensure brake pads have a minimum thickness of 1/4”.

Wheels/tires

Check tires for cuts, bulges, and abrasions on your tires. Confirm tire tread depth and inflation levels. Check All lug nuts are accounted for and in good condition. Ensure valve stem is properly secured and capped. Look out for unauthorized or illegal welds on wheel rims. Check tires are properly spaced if your tractor/trailer has duals. Confirm the hub seal/axle seal is not loose and has no visible leaks.

Rear of truck

Look at the frame to ensure nothing is broken. Check for unauthorized welds. Confirm the catwalk and steps are properly mounted and kept clear. Ensure the drive shaft is free of debris with unbroken and untwisted U-joints. Verify the exhaust system is secure and look for exterior soot, which could indicate a leak. Make sure mudflaps are also secured at the right height.

Coupling area

Check that the fifth wheel platform, apron, and kingpin are secure, not cracked, bent, or broken. Look for any unauthorized or illegal welds. Confirm skid plate is properly greased. Verify release arm, locking jaw, and slide locking pin are fully locked. See that mounting bolts are tight and none are missing. Ensure glad hands have seals in good condition with no signs of rot or leaks. Secure electric lines with safety latches in place. Check air connector is secure on both ends without cuts or abrasions.

Verify that there are no holes in the trailer’s front, sides, or floor and that all rivets are present. See that DOT tape is properly secured and not dirty. Check that all hardware is present on an untwisted, unbroken frame and that cross members are securely mounted with none missing. Ensure lights are clean, working, and not loose. Confirm landing gear is raised, securely mounted, with an operational handle. Check air lines are securely mounted, above ground, with no audible leaks. Verify tandem slide and release arm are properly mounted and locked.

Truck exterior

Make sure that the truck steps are mounted and secure.  Ensure the fuel cap is tight and the tank is not leaking. Demonstrate that the doors latch properly with hinges intact. Ensure mirrors are unbroken and securely attached. Check all the lights and reflectors are working too. This means inspecting the running lights, high beams/low beams, turn signals, hazards, brake lights, license plate lights, and reflector tapes. If driving a hazardous load , ensure you have the proper hazmat placards securely affixed.

Check to ensure your seat belt adjusts and latches properly and that there are no rips or frays. Confirm the shifting distance, room for the clutch, and that parking brake is on. Verify the steering wheel is secure and that the foot pedals are clear of obstruction. When the vehicle is on, look for the ABS light to come on and off. Make sure the windshield wipers, heat and defrost, gauges, and horns are working. Pump the brake pedal several times then apply pressure to the pedal and hold for five seconds to ensure the pedal does not move. For air brakes, confirm applied pressure, warning lights and buzzers, and valve pop-out are all working. Look for three reflective triangles , spare fuses or circuit breakers, and a properly charged and rated fire extinguisher with its pin in place.

Common issues found during pre-trip inspections

While completing a CDL pre-trip list, drivers may encounter any of these common problems. This section identifies common issues, how to address them, and how to prevent future problems too. 

Truck is leaning

Using the 3L’s you might see the truck leaning to one side. This could be a suspension problem or indicate low tire pressure.

Fix it by first checking the tire pressure and inflating tires. If that doesn’t address the problem, check the suspension. Driving a vehicle when there is a problem with the suspension, springs, shocks, or struts can cause severe damage to the vehicle.

Broken lights/warning lights

If you detect an exterior light is cracked or broken, fix it before going out on the road. If a light from the on-board diagnostic system comes on during inspection, e.g., “check engine” or “service engine soon,” address that warning as you’ll fail a roadside inspection if that light comes on. 

Gas cap missing

Damaged or missing gas caps are a common reason for failed inspections on the road. Don’t set out on your route without replacing the gas cap.

Worn tire tread

Unacceptable or worn tire treads or knots or bulges in tires can also lead to failed roadside inspections. Don’t risk going on your route with substandard tires.

How to prevent future CDL pre-trip list problems

An eDVIR or electronic driver vehicle inspection report allows you to record, compile, and store pre-trip and post-trip information on electronic devices such as computers, smartphones, and tablets. This helps motor carriers and fleets to have a centralized record of inspection history, allowing authorized users to monitor progress, pull reports quickly, and promptly address driver, vehicle, or equipment issues.

Using an eDVIR , you can get out on the road faster with the convenience and accuracy of using a smartphone or tablet to record your data while ensuring your vehicle is safe for operations. Drivers can even take and upload photos to record details and communicate with fleet supervisors for quick troubleshooting. 

Making pre-trip inspection checklists easier

CDL pre-trip inspection checklists help systemize the driver’s check of their vehicle before going out on the road. This enhances driver safety and can help reduce accidents. Consistently inspecting fleet vehicles also helps simplify fleet maintenance and avoids failed DOT inspections and reduced CSA scores. 

Pre-trip checks are part of the day to day for drivers. Motive’s customizable eDVIR technology simplifies the reporting. Drivers can assess vehicle parts against a built-in checklist in the Motive Driver app, indicate the severity of the issue, and upload photos. Fleet managers get pre-trip inspection reports in real time. Plus, the technology provides advanced reports to help managers analyze health and maintenance trends for all fleet vehicles.

What is a Pre-Trip Inspection Checklist for Class A CDL?

• April 5, 2024
• Michael Kapuschinsky
• Approx. Read Time: 8 Minutes

Pre-trip inspections are an everyday task for most Commercial Driver's License (CDL) drivers. Making sure the vehicle is ready for the road is both a safety and compliance issue.

While there is no standardized report that needs to be completed, truck drivers must have documentation showing that the inspection was done. They must also show if any issues were found and that these issues were taken care of properly.

Because it can be difficult to remember everything that should be included in a CDL pre-trip vehicle inspection, many truck drivers and trucking companies use checklists to track this inspection process.

This guide provides more information about the CDL pre-trip inspection process.

• Pre-trip inspections are a vital part of the trucking industry and can keep drivers and others safe on the road.
• One of the many advantages of using a pre-trip inspection checklist is the ability to conduct consistent assessments that are in compliance with FMCSA requirements.
• A comprehensive CDL pre-trip assessment should evaluate all components of the truck, including the exterior and interior of the truck and trailer, as well as under the hood.
• Using a service like Driver iQ can ensure you hire truck drivers who have the skills and knowledge to conduct proper and comprehensive pre-trip inspections.

Anyone who works in the trucking industry can tell you how important it is to keep your truck in tip-top shape. To ensure your truck is always in good working condition, regular inspections are necessary.

In fact, this step is so important the government requires truck drivers to conduct inspections of their vehicles on a regular basis. To make sure they don’t miss anything, many truck drivers use a CDL pre-trip inspection checklist to ensure everything is examined carefully.

This article takes a closer look at everything you need to know about CDL pre-trip inspection checklists.

• Tips for Creating Your Own CDL Pre-Trip Inspection Checklist

Truck drivers use CDL pre-trip inspection checklists to ensure all parts and systems on their vehicle are working properly before taking it out on the road.

Studies show that, on average, a truck accident occurs every 15 minutes across the United States. While truck drivers are not always at fault for these incidents, the fact that a fully loaded tractor-trailer can weigh as much as 80,000 pounds makes any accident dangerous.

To ensure the truck driver’s safety, as well as others on the road, the Federal Motor Carrier Safety Administration (FMCSA) requires CDL drivers to conduct pre-trip safety inspections before hitting the road. If any defects are noted, repairs must be made before taking the truck on the road.

This isn’t the only requirement. Truck drivers must also keep documentation showing that a CDL pre-trip inspection was completed prior to starting the trip.

Most trucking companies require drivers to complete a CDL pre-trip inspection checklist for two reasons:

• To ensure all safety features, parts, and systems are thoroughly checked
• To maintain a formal record of when the inspection was completed and by whom

Conducting the Inspection

There are a number of reasons why it’s so important for truck drivers to conduct a CDL pre-trip inspection every day, or in some cases, multiple times a day, including:

The most important benefit of conducting pre-trip inspections is the extra safety net it provides. Making sure the truck and all its components are in good working condition can prevent deadly and dangerous accidents.

Federal regulations require all CDL truck drivers to conduct pre-trip inspections. Failure to do so could result in hefty fines and delivery days. Multiple infractions could even result in the loss of your certification or CDL license.

Maintenance

Another great benefit of frequent pre-trip inspections is the ability to spot a minor problem with the truck before it becomes a larger, more costly issue. For example, replacing worn brake pads before they cause damage to the rotors can save you thousands of dollars over time.

Using a Checklist

While it’s easy to see the benefits of conducting regular pre-trip inspections, there are also a number of advantages to using a checklist to track this process.

Consistency

This ensures that all pre-trip inspections cover the same elements and that each truck driver completes the same process.

Comprehensive Check

Using a checklist requires drivers to check off each item as they inspect it. This can ensure a comprehensive inspection is completed every time.

Documentation

Using a standardized checklist can provide truck drivers and trucking companies with documentation to prove this process was completed correctly.

Below is a brief look at the importance of each step in the pre-trip inspection, followed by a list of points to check.

Exam Tires and Wheels

It’s important to examine every tire and wheel on the truck to ensure they’re safe for road conditions.

• Check tires for abrasions, bulges, and cuts.
• Ensure tire tread depth is at least 4/32 inch.
• Make sure the tire pressure is appropriate for road conditions.
• Ensure the wheels and rims are properly attached and not bent or cracked.
• Make sure all lug nuts are secure and not loose.
• Examine the hub and axle seal to ensure they’re not loose and there are no leaks.
• Ensure hub oil is at a proper level and not leaking.

Check Lights and Reflectors

This step can keep you and other drivers safe despite the time of day or weather conditions.

• Walk around the truck to make sure all lights, including running lights, high and low beams, turn signals, hazard lights, and license plate lights, are in good working condition.
• Use side mirrors to make sure brake lights are working properly.
• Check to ensure the reflector tape is properly attached and not loose or dirty.

Inspect Brakes

Properly working brakes are critical for truck drivers and must always be in good working condition.

• Make sure brake hose, the brake chamber, and the slack adjustor are secure and not leaking or damaged.
• Look for any splits, breaks, or cuts in the break line.
• Ensure brake pads are at least 1/4-inch thick.
• Make sure there are no cracks in the brake drum or bluing due to excess heat.
• Ensure the slack adjuster push rod is at a 90-degree angle with a 1-inch play or less.
• Make sure no air is leaking from the brake chamber.

Check Engine

A properly working engine can prevent downtime due to repairs and keep the truck safe on the road.

• Inspect all fluid levels, including engine oil, power steering fluid, automatic transmission fluid, coolant, and windshield wiper fluid.
• Examine all belts, including those on the alternator, compressor, and pumps, to ensure they’re secure and not cracked, split, or damaged.
• Ensure the air conditioning compressor, alternator, and water pump are secure and not damaged.
• Make sure all hoses for the pumps, power steering, oil, and coolant are secured properly.
• Ensure the alternator is secure, the wires are properly connected, and there is no visible damage.
• Check the air compressor to make sure it's connected properly and is not loose, leaking, or broken.

Conduct Coupling System Check

A secure and operational coupling system is critical for trucks carrying trailers. This safety check can ensure that there are no dangerous issues while hauling a load.

• Thoroughly check the 5th wheel platform to make sure it’s securely in place, not cracked or broken, and that there are no illegal welds around it.
• Make sure the platform apron and kingpin are properly mounted and secured with no cracks or damages.
• Ensure that the locking jaw, slicking locking pin, and release arm are secured in the lock position.
• Make sure the skid plate is in good condition and greased properly.
• Inspect all mounting bolts to ensure they’re in place and secure.
• Check electric lines to ensure they’re securely attached, and safety latches are in place.
• Examine seals on glad hands to make sure they’re in good condition and not chipped or cracked.

Evaluate the Exterior of the Truck

As part of your safety check, you should always take the time to walk around your truck and inspect the interior to ensure everything is in place.

• Ensure the truck is not leaning.
• Check to see if there are any leaks under the truck.
• Make sure all mud flaps are properly secured and not touching the ground.
• Examine the exhaust system for evidence of any issues, such as loose bolts or soot.
• Make sure the steps and catwalk are secured in place, not damaged, and free from clutter or any obstructions.
• Check to make sure all mirrors are in place and not broken.
• Ensure the fuel cap is not tight, and there are no signs of leaking.
• Make sure all doors and hinges are secure and opening properly.

Assess the Interior of the Truck

You also should check the interior of the truck to make sure everything is in place and working properly.

• Check to ensure all mirrors, windows, and windshields are clear, clean, and not chipped, cracked, or otherwise damaged.
• Make sure the seat belts are in good working condition with no fraying, tears, or cuts.
• Make sure the seat belt fits properly and adjust as necessary.
• Ensure there are no obstructions on the floor and surrounding the foot pedals.
• Check to make sure all interior elements are working, including interior lights, steering wheel, heat and defrost, light indicators, water temperature and fuel gauge, odometer, and horn.
• Check the brakes by pumping them several times before applying pressure for several seconds. After releasing, the pedal shouldn’t move.
• Conduct Class A air brake check.

What Is A CDL Pre-Trip Inspection Checklist?

A CDL pre-trip inspection checklist is used by truck drivers who hold a Commercial Drivers Licenses (CDL) to inspect each part of the vehicle before and during trips.

A daily pre-trip inspection typically takes between 15 and 30 minutes to complete.

Why Truck Drivers Should Always Use A Pre-Trip Inspection Checklist?

A thorough pre-trip inspection is mandated by both federal and state laws.

As a truck driver, you are responsible for ensuring your vehicle is safe before you hit the road.

Skipping your pre-trip inspection can lead to violations, vehicle downtime, and accidents.

A comprehensive checklist can help ensure you cover every area of the vehicle during the inspection. If you find any issues during the inspection, you should complete a driver vehicle inspection report to avoid a violation that can decrease your (CSA) scoreCompliance , Safety, Accountability (CSA) score, and reduce the risk of a possible accident.
