Our Pre-Trip Inspection Study Guide has everything you need to prepare for the Class A CDL Pre-Trip Inspection Exam . 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

Trailer Parking Brakes - Set the Trailer Brake, release the tractor brake, and then tug lightly on the trailer.

Tractor Parking Brakes- Then set the Tractor Brake, release the trailer brake, and then tug lightly on the tractor.

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 :

The Engine Compartment Section will include questions about checking the oil level and coolant levels, inspecting belt-driven engine components (like the water pump, alternator, and air compressor), and the safety devices required in the cab.

CDL Frequently Asked Questions

Getting a CDL is the first step toward a rewarding career which is why it’s so important to prepare before you begin down this career path. While each state has different rules for commercial driver’s licenses, there are federal guidelines in place as well. Some states may also offer specific preparatory programs to help you get ready to take your driving test. If you can find one of these programs, it will make it much easier for you to get your license.

A commercial driver’s license is required for any vehicle that transports more than 15 people. The United States also requires a CDL if you plan on driving a vehicle heavier than 26,001 pounds. It is also a requirement for anyone who drives hazardous cargo.

According to the Federal Motor Carrier Safety Administration (FMCSA), you have to meet certain requirements to get a CDL. While your state may have additional rules, every driver must meet the federal guidelines. As a rule, you must be at least 18 years old.  You must be 21 years old if you need to drive across state lines or operate a vehicle carrying hazardous cargo. In addition, you cannot have any criminal felonies or offenses that may disqualify you from getting a CDL.

The first step is to figure out the type of CDL that you need. Do you want a class A, B or C?  Do you need specific endorsements? There are three vehicle classes for the CDL. Tractor trailers, school buses and tanker trucks all require a different test. To get your endorsement, you will have to pass a skills test to get your permit. You may also be required to pass a written test, so make sure to study the CDL manual carefully.

CDL Class A

A class A CDL is required if you are driving a vehicle that weighs 26,001 pounds or more. It is also necessary for towing vehicles that weigh more than 10,000 pounds. As long as you have the proper endorsements, a class A license can let you drive flatbeds, tractor-trailers, tanker vehicles, double trailers, livestock carriers, triple trailers and tractor-trailer buses. A class A license may also let you drive some class B and C vehicles if you have the right endorsements.

CDL Class B

Like the previous license, a class B can be used to operate a vehicle that weighs more than 26,001 pounds. It can also be used to tow vehicles that weight up to 10,000 pounds. Depending on the endorsements that you may need, a class B license will let you drive segmented buses, straight trucks, tourist buses, school buses and city buses. You may also be able to drive box trucks like furniture delivery, couriers, delivery drivers and dump trucks. Depending on your endorsements, a class B license may allow you to drive some class C vehicles.

CDL Class C

With a class C license, you can drive a vehicle that does not meet the criteria listed in class B or class A licenses. It is intended for people transporting hazardous materials or more than 16 passengers. With a class C license, you may be able to drive passenger vans and small HAZMAT vehicles. You may also be able to drive combination vehicles not listed in the previous classes.

There are many endorsements available for commercial drivers. Once you have a class A, B or C license, you can take additional tests to get an endorsement. If you want specific endorsements, you need to have a vehicle that is equipped with the right type of equipment.  Some of the endorsements include:

– P Endorsement: This lets you drive a vehicle with a set number of passengers.

– H Endorsement: This allows you to drive hazardous materials.

– X Endorsement: The X endorsement is for tank vehicles and HAZMAT vehicles.

– S Endorsement: With an S endorsement, you can drive a school bus.

– N Endorsement: This endorsement is for driving tank vehicles.

– T Endorsement: This endorsement is intended for towing double or triple trailers.

As a rule, you will be required to take a knowledge test and get your learners permit. You must have the CLP for at least 14 days before taking the road skills test. If you plan on getting specialized endorsements, you will have to take additional road skills and knowledge tests. To get your permit, you will have to show a medical examination, a 10-year driving history, and your current driver’s license.

The written knowledge test will encompass at least 50 questions, and you will need to answer a minimum of 80 percent of them correctly to pass. If you pass, you will be required to pay a fee to get your permit.

The CDL test contains a general knowledge test, an endorsements test, and an air brakes test.  The questions on the exam are designed to test your knowledge of:

• Vehicle pre-trip inspections.
• Communicating with other drivers.
• Gear shifting and vehicle control.
• Managing space while sharing the road
• Controlling and maintaining speed.
• Identifying potential hazards.
• The dangers associated with distracted driving.
• The dangers of alcohol consumption and driving.
• Railroad crossings.
• Night driving.
• Driving in various weather conditions.
• Dealing with driving emergencies.
• Correct braking methods.
• Controlling and recovering from skids.
• Procedures after an accident.
• Medical requirements.

There are 50 questions on the CDL General Knowledge Test.  All CDL applicants are required to take the General Knowledge Test.  You can expect additional questions if you plan on pursuing endorsements.

In most states, you will have to pass skill requirements, residency rules and a medical exam to get a CDL. You may also have to take a written knowledge test.  The knowledge test includes at least 50 multiple-choice questions on highway safety and the different parts of the truck. To pass the test, you are required to score 80 percent or higher. It’s important that you prepare for this test as it has a high failure rate.

Your first step is to get a copy of the CDL manual for your state. You can get a free copy of your state’s CDL manual on this site or at your state’s Department of Motor Vehicles website or local office.  The second step involves testing your knowledge of the manual with practice tests. We offer free CDL practice tests that cover all areas of the CDL exam and the relevant endorsements.

After you have studied and passed the written knowledge test, you are ready to get a commercial learners permit (CLP). This permit lets you practice driving on public roads with an experienced driver. Before the DMV gives you this permit, they will check your driving record for the last 10 years in every state. Depending on your state, you may have to bring in proof that you are physically able to get a CDL. You may have to take a Department of Transportation medical exam before you are given a medical card. You may also be required by your state to prove that you are a resident before you are given a learners permit.

You are legally required to have a learners permit for 14 days before you can take the skills test and earn your CDL license. Depending on your state, you may also be required to have specific CDL training before you take the skills test. During the 14 days, you should practice maneuvers and inspection tests to prepare. Each test includes a road test, a vehicle inspection test, and a basic controls test. For you to pass, you must excel in all of these areas.

After you have successfully passed the skills test, you will bring your documentation to your local CDL testing office. Depending on your state, you may be able to get your CDL the same day. You may also have to wait for it to arrive in the mail. Make sure that all of your information is correct when you are at the testing office so that you do not have to fix any mistakes later or leave empty-handed.

What's a commercial driver's license.

• Class A (Combination Vehicles): Any combination of vehicles with a gross combination weight rating (GCWR) of at least 26,001 pounds provided the gross vehicle weight rating (GVWR) of the vehicle(s) being towed exceeds 10,000 pounds. Examples include tractor-trailers.
• Class B (Heavy Straight Vehicles): Any single vehicle with a GVWR of at least 26,001 pounds, or any such vehicle towing another vehicle whose GVWR does not exceed 10,000 pounds. Examples include coach buses and transit buses.
• Class C (Small Vehicles): Any single vehicle or combination of vehicles not included in Class A or Class B that is used to transport sixteen or more passengers including the driver or to transport hazardous materials. (For this purpose, federal regulations define a hazardous material as a substance that has been designated by the US Secretary of Transportation as a material whose commercial transportation may pose an unreasonable risk to health and safety or property.) Examples include sixteen-passenger vans.

How to Obtain a Commercial Driver's License?

• You must be at least 18 years old.
• Have a valid driver's license (or learner permit) for the state in which you are applying.
• Pass the CDL written knowledge test.
• Complete your medical exam and get your physical.
• Get fingerprinted by law enforcement with ID verification, or go to an authorized third-party vendor that provides computerized fingerprinting services.
• Go to a DMV office and pay the required fee to take the skills test

What Are All the Truck Parts Called?

CDL Test Questions and Answers: What To Expect? Study your state's CDL handbook. Sometimes it's hard to find the official source, so we've put together a list of the most recent official CDL handbooks for every U.S. state . If you prefer a hard copy, you should be able to pick one up at your local DMV office. Take a lot of practice tests. Taking practice tests that simulate your state's actual knowledge test will give you confidence and prepare you for the actual thing. Our CDL test questions are based on your state's official manual, so you'll know what to expect. These tests are valid for both commercial driver license and CDL permit (CLP). Watch CDL videos. YouTube is a fantastic resource, especially for pre-trip inspection.

Apply for a Commercial Driver's License (CDL)

A Commercial Driver's License is required to drive commercial vehicles such as tractor trailers, semi-trucks, dump trucks, and passenger buses (including school buses). The minimum age to apply for a CDL is typically 21. To become a truck driver, you can apply for a CDL at a local DMV office. Learn more about the three classes of CDLs that determine the kinds of commercial motor vehicles you’re permitted to drive: Class A , Class B , and Class C . There are strict federal guidelines for obtaining a CDL, and each state has its own requirements that need to be also met. You must pass both a written knowledge exam and a driving skills test, which are designed by your state.

CDL Written Knowledge Test

Your CDL test is the first step to a professional truck driving career in a trucking company. After you've studied your state's CDL handbook, the best thing you can do is either sign up for a costly CDL training program or take a free CDL practice test that simulates your state's actual knowledge test. Driving-Tests.org provides a general knowledge test, as well as practice tests for specific commercial vehicle endorsements, such as air brakes test, school bus, and hazardous material (HazMat endorsement). There's also a practice test for pre-trip inspection - it will come in handy before your CDL road test. These tests are valid for both commercial driver license and CDL permit (CLP).

Choose your state from the drop-down menu above, and you’ll be provided with a test for all CDL license types that is closely based on your state’s manual, state and federal laws, and practice questions provided by the state if available.

How Is the CDL Practice Test Structured?

Think of this as your own CDL study guide for each endorsement. Every practice test has multiple-choice questions in the same format you’ll find on your state’s CDL test. These questions are phrased like the ones on your state’s official knowledge test. Most of the questions come with a hint to help you choose the right answer. Each correct answer comes with an explanation that has been carefully written to help you become more familiar with the topic of the question. We want you to be able to answer questions on those topics correctly even if they are worded a bit differently. Please read each explanation; it is based on your state’s CDL manual and DMV/DOT website.

Which Topics Are Covered?

This practice exam covers a wide range of topics that you’ll need to know about to pass your CDL knowledge test and enter the trucking industry. These topics include aggressive drivers, braking techniques, cargo safety, distracted drivers, drunk driving laws, emergency preparedness, road and weather conditions, and safe backing. No, we certainly did not forget about air brakes, combination vehicles, or hazardous materials! These topics are complex enough to deserve separate treatment. Just as states typically require you to pass specialized knowledge tests on those topics, we offer our own specialized practice tests on air brakes, combination vehicles, and hazardous materials. By studying our CDL practice tests, you'll be on your way to obtaining your Class A CDL, Class B CDL, or Class C CDL license . Remember that you'll also need to fill out the Medical History portion of the MER form (MCSA-5875) and also obtain a copy of the Medical Examiner Certificate form (MCSA-5876).

How Many Times Should I Take the CDL Practice Test?

We recommend that you keep taking the test until you become fully comfortable with the subject matter and receive a score high enough to boost your confidence about your upcoming CDL exam. A high score will bring you closer to passing your CDL knowledge test, so practice as many times as you’d like. There are no fees, and you won’t even have to register. Good luck now and on your CDL test. Drive safely!

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 will 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.
• The air pressure gauges should build to governor cut out.
• Your truck should have a fire extinguisher, three red reflective triangles and spare electrical fuses.
• Demonstrate both the heater and defroster are working properly.

Horns (Air Horn and City Horn)

• Blow both horns to make sure they are working.
• Check the left turn, right turn, four way flashers and high beams; also point these out on the dashboard.
• Make sure transmission is in neutral and then 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 should not be ripped or frayed and should adjust and latch properly.
• The engine oil pressure gauge should rise to normal operating range.
• Trailer Parking Brakes – Set the trailer brake, release the tractor brake, then tug lightly on the trailer.
• Tractor Parking Brakes – Set the tractor brake, release the trailer brake and tug lightly on the trailer.
• 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 should be charging between 13 and 14 volts.
• The water temperature gauge should also rise to normal operating range.
• The windshield and mirrors must be clean, with no obstructions and in proper adjustment.
• Demonstrate the wipers and washers are working properly by spraying the windshield.

Back to top of In-Cab Inspection and Brake Tests

During a CDL pre-trip inspection, truckers inspect many aspects of their commercial vehicle, including the overall safety of the vehicle; major hoses, fluid levels, and vehicle belts; the clutch or gear shift; and emergency equipment. The driver demonstrates their knowledge by walking around the vehicle, checking various safety components and explaining why each part should be checked for safety.
