Our study guide will cover the pre-trip inspection terminology as well as a thorough list of all of the parts you will be inspecting on the vehicle. For each part you will be inspecting there will also be a list of items you will be checking for. Our study guide is broken down into the following sections:

• What You Need to Know About Pre-Trip Inspection

Pre-Trip Inspection Practice Questions

• Pre-Trip Inspection Checklist

Pre-Trip Inspection Videos

Pre-trip inspection printable resources, what you need to know about the pre-trip inspection.

The Pre-Trip Inspection is a thorough inspection of the vehicle and all of its major systems. Inspecting the vehicle before driving each day is a Federal requirement and normally takes about 15 minutes. It must be logged in your logbook as "on duty not driving."

You will have to do thorough safety inspections of the coupling system, the vehicle lights, engine compartment, tires and brakes, the chassis, the fuel tanks, and an in-cab inspection.

The following information is a brief summary of Daniel's Complete Pre-Trip Inspection taken from our oustanding free PDF download:

Engine Compartment

You will be checking the engine compartment for any sort of leaks. You will also be checking to see if all components are properly mounted and secured. None of the mounts must be cracked, bent, or broken.

You will be checking all hoses to make sure they aren't leaking, frayed, or sliced and the fluid levels including the oil level, the coolant, and the power steering fluid.

You must check the components like the water pump, the power steering pump, and the alternator to make sure nothing is leaking, the belts are not frayed, and that everything is properly mounted and secured.

From inside the engine compartment you will also find the steering system, the front suspension system, and the front brake system. All components of these systems must be properly mounted and secured without anything being cracked, bent, or broken. Finally you will be checking the tires, rims, and axle seals to make sure the tires are properly inflated, the rim isn't bent or cracked, and the axle seals are not leaking.

Fuel Tank And Battery Area

You will be standing along the side of the tractor doing a series of checks on the mirrors, fuel tanks, batteries, exhaust system, and more. You will check to make sure nothing is bent, cracked, broken, or leaking.

Check the mirrors, door hinges, door handle to make sure nothing is cracked, bent, or broken. Check to make sure there is no fuel leaking and that the fuel cap is secured and the gasket is not missing.

Check the exhaust system to make sure nothing is cracked, bent, or broken. Check the driveshaft, cat walk, and steps to make sure nothing is cracked, bent, or broken.

Check the frame and crossmembers for structural integrity. Check the air lines going to the trailer to make sure they're properly connected and that there are no abrasions, bulges, or cuts. Make sure the gaskets are present.

Check the suspension system and brakes on the drive axles, making sure nothing is cracked, bent, or broken. Make sure the brake linings are the proper thickness and that the air bags and properly inflated. Inspect the brake chambers, slack adjusters, and pushrods are properly mounted and secure. Not Cracked, Bent, or Broken. With the brakes released and pulled by hand, the Push Rod should not move more than 1 inch.

Check the rims, tires, and axle seals of the drive tires for proper inflation, no leaks around the seal, and the lugs are all present and secured.

Coupling System

You will be standing where the tractor and trailer are connected and you'll start by checking the electrical line and air lines to make sure they're properly mounted and secure at both ends. No abrasions, bulges or cuts. Not leaking air. Make sure the electrical line has no wires exposed. Check the gladhands to make sure the seals are in good condition, no cracks or signs of dry rotting. Not leaking air.

Check the skid plate of the fifth wheel and the apron of the trailer to make sure there is no debris and nothing is cracked, bent, or broken. Make sure the fifth wheel is properly greased. Also make sure there is no gap in between the fifth wheel and the trailer apron once the tractor and trailer are coupled. Make sure the kingpin of the trailer is properly mounted and not cracked, bent, or broken and that the locking jaws of the fifth wheel are properly secured when the tractor and trailer are coupled.

Check the mounting bolts where the fifth wheel attaches to the tractor frame. Make sure there are no missing bolts and that everything is secured properly. Check the locking pin if you having a sliding fifth wheel to make sure it's properly locked into place.

Make sure that there is the proper clearance space between the tractor mudflap and the trailer landing gear so that they don’t hit each other when making a turn.

You will start inspecting the trailer at the head board, which is the front wall of the trailer. Make sure there are no holes or missing rivets. Check the landing gear to make sure it is properly mounted and secure. Not cracked, bent, or broken. Make sure the fully raised and the handle is secure in the cradle when the tractor and trailer are coupled.

Check the frame and crossmembers under the trailer to make sure they're not cracked, bent, or broken. Check the tandem frame and release pins to make sure the frame is in good condition and the release handle and locking pins are in the fully locked position.

You will check the entire suspension and brake system for the trailer tandems the same way you did for the drive axles of the tractor. You will also make sure the mudflaps are properly secured. For dual tires check to see that there is proper space between the tires and there is nothing stuck between the tires.

Check the rear door and hinges to make sure they are properly mounted and nothing is cracked, bent, or broken. Make sure the door seals are not worn, torn, or dry rotted.

Light Check

You will be checking all of the lights and reflectors on both the tractor and the trailer. Check the reflectors and reflective tape to make sure they are properly mounted and secure, not cracked, bent, or broken, and clean and illuminated. Check that you have the proper color of amber to the front and sides, and red to the rear.

Start by turning on your marker lights and headlights. Now walk around the entire truck and trailer and point out the lights. Give the function of the light and the location. You should then ask your examiner to help you check your five functions.

While you're sitting in the drivers seat, the examiner will stand to the front of the truck, then behind the trailer. He will then check your Turn Signals, Four Way Flashers and Brake Lights. You must do each function at every location.

The five locations that you must check your lights:

• Front of the Truck
• Both sides of the Truck
• Rear of the Truck
• Both sides of the Trailer
• Rear of the Trailer

The Five Functions you are checking for:

• Left Turn Signal
• Right Turn Signal
• Four Way Flashers
• High Beams/Low Beams
• Brake Lights

In-Cab Inspection

The in-cab inspection and air brake check will cover the various gauges and systems inside the cab along with several tests to make sure you air brake system is working properly.

You will start by checking the following:

• Seat Belt- Properly Mounted and Secure. Not ripped or frayed Adjusts and latches properly.
• Fire Extinguisher- Properly Mounted and Secure. Fully charged
• Three Red Reflective Triangles- My three red reflective triangles are GIVE LOCATION
• Spare Electrical Fuses- My spare electrical fuses are GIVE LOCATION

Service Brake Check - Release both Tractor and Trailer Brakes. Now 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.

Air Brake Test

The air brake test will consist of a leakdown test to make sure your air brakes aren't leaking air and losing pressure. It will also test the warning lights and buzzer to make sure the driver gets the proper warning if the air pressure drops too low.

There are three stages to an Air Brake Test

#1: Applied Pressure Test

#2: Warning Light and Buzzer

#3 Tractor/Trailer Protection Valve Pop Out

Applied Pressure Test: Build the air pressure to governor cut out. Put the truck in the lowest gear. Then turn off the engine Immediately turn the engine back on. Push in both the tractor and trailer valves. (This will release the parking brakes.) Push and hold the Brake pedal fully. Allow the gauges to stabilize. Announce the gauges have stabilized and the Primary and Secondary PSI. With the Brakes fully pressed, you should not lose more than 4 PSI in one minute. Announce that you are listening for air leaks during that minute.

Warning Light and Buzzer Test: Pump down on the Brake pedal until the warning light and buzzer comes on, at or before 60 PSI.

Tractor/Trailer Protection Valve Pop Out Test: Pump down on the brake pedal until both the tractor and trailer protection valves pop out. They should both pop out between 40 and 20 PSI.

We have a ton of Pre-Trip Inspection Practice Questions along with the answers and a complete scoring system in our Free Online CDL Practice Tests :

How To Study For the CDL Pre-Trip Inspection

As a professional truck driver, there are crucial tasks to complete to be safe and stay compliant. One of the most important tasks is a CDL pre-trip inspection. Not only does this keep you and everyone else on the road safer, but it is required to remain compliant with FMCSA rules and regulations.

The nation has deemed truck drivers essential, and the industry needs new drivers more than ever. Roadmaster can help you start a new high paying career in about a month. And as a professional truck driver, there are crucial tasks to complete to be safe and stay compliant. These are the very things you’ll find when studying and testing.

One of the most important tasks is a CDL pre-trip inspection. Not only does this keep you and everyone else on the road safer, but it is required to remain compliant with FMCSA rules and regulations . It also keeps you in-the-know about how your truck is performing and if there are any issues that need to be addressed.

Here is a guide on how to study for a CDL pre-trip inspection.

What Is a CDL Pre-Trip Inspection?

The definition of a pre-trip inspection is self-explanatory – it is a complete assessment of the trailer, truck, and cargo before each trip. The DOT has a pre-trip inspection list and the guidelines dictate to follow their list. Rules dictate to document everything using a DVIR or driver vehicle inspection report according to federal law FMCSR Section 396.11.

A professional truck driver must have any problems found with the truck and trailer addressed before leaving. This includes things like damage or other issues affecting the trip. The inspection process should be thorough and doesn’t take long – around 15 minutes or so. During this time, the driver must report as on duty,  not driving.

This is one important aspect to learn in becoming a driver, so studying it is crucial.

Why Is It Important?

Your safety and the safety of others.

Any kind of issue with your truck can cause safety concerns. From damaged brakes to an unsecured load – these are the very things you are looking for with the inspection. It keeps you on your toes and ensures you know that every trip is the safest possible. This also has the added benefit of keeping you on the road more. You’ll avoid violations that ground you till it’s fixed. And you can better avoid an accident because of a fixable issue.

By learning this information and studying it, you’ll have the knowledge you need to prepare for the exam.

It’s the Law

It is your responsibility as a professional truck driver to ensure your truck is safe and road-ready. This means not only is it safe to operate, but it is free of issues that cause accidents. This has other benefits too. By catching any problems yourself, you are less likely to get a violation.

It Saves Extra Costs

With any situation, catching a problem before it’s a bigger problem is ideal. Instead of finding out you have a major repair, you might be able to find it while it’s still easily fixable. Plus, you have time to take it to a shop rather than a roadside service that costs more and is less convenient. And let’s not forget about how expensive towing is.

Steps in Studying for a CDL Pre-Trip Inspection

Now that you know how important a CDL pre-trip inspection is to your livelihood, here are the steps in conducting one. We showcase these steps to help you study for what the exam requires.

Under the Hood

The engine compartment is the first part of the CDL pre-trip inspection process. This is before you start the truck and the inspections include:

• Make sure kingpins, ball joints, and shocks look good and have lubrication
• Check fluid levels including windshield washer fluid, coolant, and oil
• Look at steering axle tires for uneven wear
• Look for fluid drips or leaks in and around the engine
• Secure the dipstick and tighten any loose caps
• Look for wear or damage to belts and hoses
• Check the blade and fan belt for cracks, nicks, or any other damage
• Check wiring for damage like frays or misplacement
• Air conditioner compressor mounting secure
• Ensure engine air ductwork has secure clamps and no cuts
• No exhaust leaks or oil in the turbocharger
• Check fuel water separator, radiator brace, water pump, pitman arm, oil filler cap
• Inspect engine coolant reservoir, steering shaft, and brake master cylinder

If you find anything wrong, notate it in the DVIR. Notate important information and use photographs. The truck cannot leave until you appropriately fix these issues.

Take a Walk Around

Do an external inspection next. This is where you walk around your truck checking for problems. These include:

• Check all tires for proper pressure, damage, and wear and tear
• Check valve cap, outer oil seal, lug nuts, and hub oil
• Look for proper positioning in brake pads and that they are in good shape
• Inspect brake drum, lining, inner oil seal, slack adjuster, brake line, and chamber
• Inspect airlines and the electrical cord for proper connection
• Inspect the landing gear to ensure the legs are up and secured
• Ensure the 5th wheel is securely coupled to the trailer
• Look for mirror damage such as nicks and cracks
• Ensure doors close properly with secure hinges

Start Your Engine

Before leaving your location, you must ensure the engine is mechanically sound. These key components of the last inspection are:

• With the clutch depressed and the truck in neutral, start the engine
• As you ease off the clutch, idle the truck at 650rpm
• Check your gauges to ensure everything is as it should be
• Turn on your flashers and lights and step out to make sure they are all working
• Look under the hood for leaks and secure belts
• Make sure all lights are working properly

After this inspection, notate any anomalies in the DVIR. This includes things like repairs or part replacements.

The Last Steps

The last step involves moving your truck. Make sure there is nothing in the way or anything that causes a safety hazard.

• Drive forward a few feet and use the trailer brake, making sure the trailer is coupled and the brake works right
• Pull forward a few feet more, using the foot brake to stop

Look for anything not up to par and report it. This is one of the most repetitive tasks you’ll do and the most common. And therefore, it is on the test. You also need to know when to do these steps:

• Each start of the day
• After 10 hour breaks
• Every 24 hours
• When you pick up a new trailer

Ready To Learn More?

These are steps to learn that are on the test. Study these components of the CDL pre-trip inspection so it prepares you to ace the exam.
