5-step Brake Test

Explain each step before performing it. With the first 2 steps, you’re either trying to move the vehicle, or you are moving the vehicle. The engine must be ON for the first 2 steps. 1) Parking Brake: release trailer brake (push RED valve IN); slowly release the clutch, tugging lightly against the parking brake. Push clutch in. (Leave everything in the truck as it is). 2) Service Brake: (brake pedal) release parking brake (BOTH valves should be IN), pull forward to 5 mph, depress clutch and brake while lightly gripping the steering wheel; check if vehicle pulls to the left or right. (Leave everything in the truck as it is).

**Turn the engine OFF, and turn the key ON for the next 2 steps. You’ll need power for your gauges.**

Air Compressor check: perform a Safe Start. Idle up the engine (1200RPM) until the secondary air tank reads 85psi. At 85psi begin counting. The air pressure must rise from 85 to 100psi in 45 seconds or less. Next, fast idle the truck up to 120-140psi, at which point the governor cut-out should occur. Psshhh!

Air Pressure Gauges

Emergency equipment, heater and defroster, lighting indicators, oil pressure gauge, parking brake, service brake check, water temperature gauge, windshield and mirrors, windshield wipers and washers.

The last section is In-Cab Inspection and Brake Tests. For the In-Cab Inspection you will once again want to make sure all of the following components are properly mounted and secure. As well as the following:

Air Brake Test

There are three stages to an air brake test:

• Applied Pressure Test – When doing the Applied Pressure Test, you will 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 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.

CDL Pre-Trip Inspection Learning Center

The Pre-Trip inspection test is an important part of the CDL test – and one of the toughest state tests to master. It involves memorization of many parts of a commercial motor vehicle (CMV). CMV drivers are required to explain to the examiner each step in the inspection process. Even more importantly, mastering the Pre-Trip will be a skill that helps you throughout your truck driving career.

New: To help you remember key parts of the Pre-Trip, check out our new Pre-Trip Inspection Practice Tests.

Learn How to Perform a Proper CDL Pre-Trip Inspection.

There are lots of videos on pre-trip inspections. Many are well done, some not so much. We’ve decided to narrow it down to one so you can focus. The video we selected had to be easy to hear, see, and understand. It couldn’t be too complicated, but at the same time had to be thorough and cover everything. The instructor also had to have a logical system of doing things that would help you quickly master the inspection. The following video accomplishes all this.

Watch this video from Apex CDL Institute on a Class A Pre-Trip Inspection. Just sit back and take it all in the first time. Then, go back and watch again, this time pausing the video at key points and taking notes.

Note: Not all parts mentioned in this video will be located in the same place. It depends on the truck you’ll do the pre-trip on. Truck and engines vary greatly, so you must first get familiar with where these parts are on YOUR truck.

Quick tip: Work in a routine. Develop a personal system of doing things. Left to right, top to bottom, etc. This will prevent you from missing anything as you’ll check the same things every time.

This is NOT just about passing the Pre-Trip portion of the CDL test. Mastering this process will:

• Keep you and others safe – and alive!
• Keep you on the road – and not out of service because of vehicle violations
• Keep you making money . That’s ultimately why you’re doing all this, right? You’re really only making money when the wheels are turning.

CDL Pre-Trip Inspection Test and How To Memorize It

The pre-trip is one of the things that students fear the most and fail the most. Let’s face it, the pre-trip is intimidating because there is so much stuff to memorize. The key to learning the pre-trip inspection is preparation, memorization, and repetition. Don’t go away, in this article I have exactly what you need to make sure you pass it the first time.

It is going to take time for you to memorize everything and the only way to do this is by repeating it over and over.

Hopefully, the school where you are being trained is giving you enough time to practice it everyday you are there.

I can’t stress that enough, regardless of which method you use below you need to repeat it daily and practice on your own.

Don’t expect that your run through once a day with your instructor is enough, it isn’t.

In this article I’m going to give you 8 tips that will help you memorize the pre-trip so you are able to pass it your first time and move on with your driving career.

1. REPETITION!

The only way to memorize the pre-trip is to repeat it over and over. Start with the engine area and work your way around the truck and finally inside the cab.

There is no way around consistent repetition. The more you do it the more you will memorize it. It’s just that simple.

Now that we have established how important repetition is I want you go through the rest of this list and figure out which method (or methods) works best for you and then repeat it over and over.

2. Record Someone Else

You can use YouTube to find a video of someone doing a pretrip and for the most part they work pretty well (more about YouTube later).

Take it a step further though. Ask someone (like and instructor or friend) to do a pre-trip and video record them.

While they are doing it try to use the zoom function on your camera so that you know what the parts look like and what is being checked.

Students that I come across have said that this method works really well because you have quality video and audio. Just watch your recording over and over and this stuff will be engraved in your brain.

Just make sure you are absolutely sure that the person you record knows what they are doing and are showing you everything. You don’t want to watch a video that skips anything that will be on the test.

3. Smaller Chunks

Break down the pre-trip into smaller chunks so that it is not overwhelming. If you think about memorizing everything at once it will be a daunting task.

My suggestion is you learn your air brakes first, then the inside of the cab, the engine compartment, and then the rest of the truck. You can chose any order that you want to as long as it helps you out.

Memorize each part and then tie it all together. You will find that learning the pre-trip is much easier if you do it this way.

4. Use Your Imagination

Do this while in bed before you fall asleep. Warning: the pre-trip is going to consume a lot of your attention during training, even while you sleep!

When you wake up go through a video you found on YouTube or the one you recorded (see #2) and correct any errors you made.

5. Find A Truck

It really helps if you have access to a truck. Pictures alone are not enough. Most of you are probably getting your training through a private school, company sponsored training , or community college.

All of these will give you access to an actual truck and should be taking time each day to practice the pre-trip.

Take advantage of this time with the truck to practice your pre-trip as much as possible. When class ends try to stick around to get in some extra practice, this could be the difference between passing and failing.

6. Watch A Pre-Trip Video On YouTube (not straight through)

There are a lot of videos on YouTube that you can choose from. Let me save you some time, these two (below) is the best because it has good audio and video quality, is accurate, and is easy to follow.

Don’t watch the video straight through over and over. Like I mentioned earlier you should chunk it into smaller sections.

Watch a section, pause it, and list off the names of the parts and things to look for. Play it again to see if you are getting them correct. When you finish one section go on to another section until you finish it.

Don’t move on to a new section until you have memorized the section you started. When you complete all the sections you should be able to watch the whole pre-trip and repeat everything on it from start to finish.

If you want to challenge yourself a little try mixing up the sections so that the sections that was last is now first. This will let you know if you are really memorizing everything.

7. Use A Checklist

Probably the most popular ways to memorize the pre-trip is to use a checklist. No doubt that wherever you are getting your training at is already giving you a checklist to use.

Use it. A lot.

Not all checklists are done in the same order but they should all cover the same stuff. I like this one here (printable PDF document) by the people at Trucking Truth , it’s easy to follow and is accurate.

Every possible thing that you will need to identify during the pre-trip is on this checklist.

8. Use Pictures/Diagrams

There are a ton of picture resources out there that will help you memorize the test. Just do a search for “cdl pre-trip inspection pictures” and you will find a ton of stuff.

The picture I like most are these (link to PDF) by Driver Solutions. The pictures are easy to see and distinct arrows are used to point to each part. Along with pictures is an explanation of what to look for and what to say for each individual part.

What Is The Pre-Trip Inspection?

The pre-trip inspection is an inspection of the commercial vehicle including the cab, engine compartment, and exterior.

A driver of a commercial vehicle is required, by federal law, to complete one every day before driving the vehicle and at least once in a 24 hour period. Every single time you begin driving your truck you will have to complete a pre-trip.

The purpose of it is to make sure that the vehicle is safe to drive.

This gives you a chance to get whatever is wrong fixed. If you miss something and are inspected it could result in citations by the DOT.

A lot of drivers find it to be a pain in the rear but you really need to do it every single time you drive your truck. Don’t listen to the irresponsible driver at the truck stop that tells you it’s okay to skip it. It’s not okay.

How Long Does An Inspection Take?

A pre-trip usually takes about 15-45 minutes to complete. It really depends on the type of truck you are inspecting and your experience.

After several years of driving it’s inevitable that your pre-trip is going to be quicker because you are better at doing it and you know what to look for.

As a new driver you should take your time and make sure you do it right. Make it a habit to always conduct a thorough inspection so that you run into less problems while on the road.

What To Say During The Pre-Trip Test

Knowing what to say is important during the test. There are some specific language the person testing you is going to be listening for. More than likely you already heard these phrases but here is an easy way to remember what to say:

PMS— Properly Mounted, Secure ABC— Abrasions, Bulges, Cuts CBB— Cracked, Bent, Broken

There are some tricks that you can use to make sure you say the right thing, here they are: 1 . If its mounted (almost everything is) use the words, “Properly Mounted, Secure” (PMS) 2. If its rubber use the words, “Abrasions, Bulges, Cuts” (ABC) 3. If it’s metal or another hard surface use the words, “Cracked, Bent, Broken” (CBB) 4. If it has fluid or air going through it or in it remember to say, “Not Leaking”

This language shouldn’t be new to you, hopefully the school that is training you has already taught you this stuff.

What Should You Cover During The Pre-Trip?

The areas that you should cover include the coupling system, light check, in-cab inspection, engine compartment, trailer, and drivers door fuel area. Make sure that you are prepared for all of these.

Also, keep in mind that CDL schools/classes may cover the pre-trip in different orders. It’s okay though, they all cover the same stuff. The order that you practice is probably going to be different from someones in a different school/class.

There is no correct order as long as you memorize everything.

What Will Be Tested On The Actual State Pre-trip Inspection Test?

You will be required to perform a pre-trip for the light check, the in-cab inspection, and the coupling system. These 3 areas you have to complete.

After completing those 3 areas your examiner will have you perform one of the following: the engine compartment, trailer, drivers door fuel door, or the entire vehicle.

You will not know ahead of time which one the examiner will choose. This is why it is crucial that you know all the areas.

What Else You Can Do To Prepare?

Aside from the ways listed above to help you memorize the pre-trip there are some other things you can do.

One thing you can do is try answering some practice tests like these here from Trucking Truth. There are 5 free practice tests you can take.

I really find that these practice tests reinforce what you need to know for the real test. It’s worth your time try them out just to see how you do.

What If You Fail The Pre-Trip?

If you do fail the pre-trip you are able to retake it. Make sure you know why you failed the test, ask the inspector if he/she can specifically tell you what you did wrong.

This is usually never a problem because the inspectors want you to know what you missed so that you can pass the test the next time.

One more thing, don’t be embarrassed because you didn’t pass it on your first try! This happens to a lot of people! You are not the only person that will fail the pre-trip and you won’t be the last.

Study what it is that you missed/did wrong and pass it on your second attempt.

Extra Tips For Passing The Pre-Trip Test

Probably the most common reason people fail the pre-trip is because they are nervous.

The two things that will help you out the most is to always remember that the pre-trip is a verbal contact test.

As you start walking towards the vehicle you should already be looking for any leaks under it, broken marker lights, loose mirror brakes and anything else that seems out of place.

BE VERBAL! Your number one priority is to make sure the examiner knows that you know what you are talking about. The more you talk the greater your chances are to pass the test.

Even if it might seem you are going overboard just keep going. Examiners tend to like when testers are verbal.

http://www.truthabouttrucking.com/fls/Pre_Trip_Inspection.pd

CONTACT! The second most important thing you can do is make contact with the item you are describing.  For example, as you are explaining the radiator brace you need to make sure you point to or put your hand on the brace as well.

Your examiner wants to make sure that you actually know what the item is that you are explaining.

Make sure you are pointing the the correct item though! Don’t describe the radiator brace while pointing to the turbo!

Again, make sure you are VERBAL and CONTACT every single item (correctly) that you are describing.

Now go pass that test! Good luck driver!

Pre-Trip Inspection Checklist CDL

What is a CDL pre-trip inspection checklist?

Everyone prefers being safe than sorry, that’s a fact — and if you’re behind the wheel with a class A commercial driver’s license (CDL), a well-performed pre trip inspection on your vehicle is the definition of that safety. Pair pretrip inspection with regular maintenance, and you’re all set for a safer, bump-free ride. Oh, and just so you know, it’s both good practice and the law! 

Every driver must conduct one pre-trip inspection a day — that’s the bare minimum! Read on to learn more about this procedure, study the pre trip inspection checklist from our experts, and lay your hands on an excellent CDL pre trip inspection cheat sheet. 

How long does a pre-trip inspection take to complete?

A CDL pre-trip inspection is your truck’s head-to-toe travel prep that helps pinpoint any issues well in advance for the purpose of avoiding breakdowns, delays, and accidents. Do it at the start of your shift, after a 10-hour break, or when you switch trailers. 

With regard to how long your CDL class A pre trip inspection should take, there’s no strict time limit. But if your rig’s in good shape, you’ll likely be done in 15-30 minutes. All in all, your pretrip inspection boils down to a solid 30-60 minute top-to-bottom checkup that should be logged as “on-duty, not driving.”

Truck Pre Trip Inspection Checklist: What Things Should You Check Before a Trip? 

To get your CDL, you’ve got to pass a tougher pretrip test compared to what most drivers usually perform — it’s that basic daily checkup, but on steroids. Don’t lose your head over it, though, because our expert-provided Class A pre trip inspection checklist below covers everything you need to nail it. So, study our pre trip inspection checklist with pictures below and memorize it religiously. 

1. Engine Compartment: Under-the-Hood Checkup

• Fluids: No Leakage, No Problem . Check your coolant, oil, and power steering — there should be no leaks. Make sure the hoses aren’t cut or cracked — and verify if they are tight at both ends. Confirm the fluids are at the right level with your dipstick.
• Belts: Keep ‘Em Tight & Right . Alternator, pumps, compressor — all belts should be securely fastened and with not even a single crack or fray. Give them a little tug, make sure there’s just a little wiggle room, no more than 1/2″ to 3/4″ of slack.
• Hoses: Tight, Tough, Leak-Free . Check all hoses, from power steering to coolant, on both sides. They need to be tight on both ends, with no splits, cuts, or leaks in sight.
• Air Compressor: Hidden but Crucial . You can’t see it easily, but you must make sure your air compressor is firmly in place, well-protected from cracks, breaks, or leaks.
• Alternator and Water Pump: Wired and Hosed Right . Make sure all the wires on the alternator are hooked up and the water pump’s hoses don’t leak — all of this makes up the must-follow CDL pre trip inspection checklist points.

2. CDL Pre Trip Truck Front Check: Steering, Shafts, and Links

• Steering Gear and Hoses: Leak-Proof and Secure . Make sure the steering gearbox and hoses are in good shape — no damage or leaks. Hoses should be securely fastened at both ends.
• Steering Shaft: Straight & Sturdy . Check that your steering shaft and column are perfectly aligned — no twists, turns, or cracks.
• Pitman Arm: Nuts and Pins, Secure & Sound . Verify that the Pitman arm’s nuts and cotter pins are all there and tightened up.
• Drag Link: Rubber Intact and Greased . Make sure the rubber on the drag link is smooth and well-lubed — it should be butter-sliding.
• Control Arms and Tie Rod: Tight & Unbent . Check that your tie rod is tight and in one piece with no cracks or bends; the control arms should also be rock-solid.

Before you proceed reading, take a closer look at the CFL pre trip inspection pictures from our experts below. The first one is the general CDL vehicle inspection memory aid and the second one is pre trip inspection CDL engine compartment diagram for your better visual understanding.

3. Driver’s Side Basics: Mirrors, Doors, and Fuel Check-Up

• Mirrors: All Set and Shiny . Confirm that the mirror’s bracket is firmly fastened and the mirror is spotless and intact. 
• Door and Hinges: Smooth Operation and Sealed Tight . Test that the door swings smoothly and latches well, with hinges holding strong. Check that the door seals are whole and not rotting away.
• Steps and Fuel Tank: Solid Steps and No-Leak Tank . Make sure the steps are firmly mounted and can handle a good stomp. The fuel tank should be tight, with no leaks and a well-sealed cap.

4. Back-End Basics: Shaft, Exhaust, and Frame Check

• Drive Shaft: Straight & Clean . Make sure the drive shaft is straight, the U-joints are unbroken, and there’s no debris hanging around.
• Exhaust: No Wobbles or Leaks . Make sure the exhaust isn’t wobbling and there’s no soot showing leaks — everything should be snug and clean.
• Frame: Strong & Clean . Check that the frame is whole and free from any unauthorized welds or damage.
• Catwalk and Steps: Solid & Clutter-Free . Make sure the catwalk and steps are securely attached and free from any stray objects — they should be solid and clean.
• Mudflap: Properly Set and Unscathed . Confirm the mudflap is fastened well, undamaged, and positioned at the right height — yep, your must-study pre trip inspection CDL checklist is quite lengthy. 

5. Coupling System Check: Kingpin, Pin, and Everything In-Between

Take a close look at the coupling system as part of your pre trip inspection CDL inspection: check that the kingpin and sliding fifth wheel locking pin are locked in place. Make sure air lines, apron, electrical connections, and glad hands are in good shape and not tangled. The fifth wheel platform should be firmly mounted without cracks or questionable welds, and the skid plate should be well-greased. Make sure all mounting bolts are tight and the release arm is securely locked. Confirm that the kingpin is rock-solid, the locking jaw is hugging it tight, and the apron and fifth wheel pin are all locked and loaded.

6. Brake System Check: Inside and Out

Inspect your brakes thoroughly, inside the cab and out. Adjust the slack adjuster properly, confirm that brake linings are thick enough, and make sure air lines are leak-free. Examine the brake hose and chamber for leaks, check that the slack adjuster and push rod have the right play, and confirm the brake drum isn’t overheated. Finally, make sure your brake pads are clean, with at least ¼” thickness, and no oil or debris.

7. Trailer Tune-Up: Very Important Pre Trip Checklist Point

Give your trailer an in-depth inspection to make sure it’s ready for a secure connection. Look for any cracks, bends, or missing parts in vital areas like the headboard and frame. The landing gear should be fully up and not damaged, and doors should latch smoothly with no worn seals. Check that the tandem release handle and locking pins are properly secured. Inspect the airbags for any leaks or damage, and confirm that the springs, u-bolts, and shock absorbers are in good condition. The torque arm and bushings should be solid and intact.

8. Shine Check: Lights & Reflectors 

Make sure every light on your rig is shining bright and clear. Check that all exterior lights, turn signals, and warning lights are working and the lenses are spotless. Make sure your reflectors are clear and smooth — just like your freshly polished mirror. All running lights, high and low beams, turn signals, hazard lights, and brake lights should function — check that, too. Also, make sure that reflector tapes are clean and not worn. 

9. Tread Lightly: Wheel Inspection

Last but not least in this pre trip inspection checklist, give the wheel system some attention. Check that wheel rims are free from sneaky welds, and inspect steer tires for any cuts or bulges. Make sure tires are inflated to the manufacturer’s specs, and don’t forget the valve stems should be snug with no hissing leaks. Lug nuts should all be in place and free of rust or cracks, while hub and axle seals need to be tight and leak-free. We hope this printable CDL pre trip inspection cheat sheet from our experts comes in handy in your challenging behind-the-wheel endeavors!

How often should I perform a pre-trip inspection?

Daily! Yep, every single day you drive, you need to log a pre-trip inspection. Starting your day with this check-up helps catch any issues early, and thus drive confidently. Don’t forget to rely on our pre-trip inspection checklist when you’re just beginning to get to grips with this procedure.

Can I delegate the pre-trip inspection?

We understand that you may be tempted to pass the responsibility, but the pre-trip inspection is a driver’s job. You’re the one behind the wheel, so getting to grips with the pre trip inspection study guide PDF and then making sure that everything is safe is your must-do.

What must you check before transporting a sealed load ?

You can’t inspect sealed loads, but keep an eye on those weight limits. Dry bulk tanks are top-heavy, so they can wobble like a dancer with two left feet. Take it easy around curves and turns — slow and steady wins the safety race here.

What should I do if I find a problem during the inspection?

Deal with it fast or give your maintenance team a shout before you drive off. A quick fix today keeps the big mess away tomorrow.
