Learn about how to conduct a Pre-trip inspection for your car and truck driver’s licence test.

The Pre-trip inspection is to show the examiner that your vehicle is roadworthy. Make sure you go over the pre-trip inspections with your driving instructor – they will be able to explain any specific terms you are having trouble with. You should practice with your instructor before your driving test so that they can assess how well you did.  

What do you have to do in the Pre-trip inspection?

You have to conduct an interior and exterior check on the vehicle in order to show that it is roadworthy for the driving test. You should know which items need checking and what order they need to be checked in: start on the right hand side mirror and work your way around the vehicle in a counter-clockwise circle (remember to repeat items which occur both on the right and left hand side of the vehicle, such as mirrors).

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
• Volmeter, Oil Pressure Gauge, Water Temperature Gauge, and Air Pressure Gauge all show proper operation
• City horn and air horn functioning properly
• The windshield and mirrors are clean, no cracks or breaks, no obstructions. The mirrors are in proper adjustment.
• Windshield Wipers and Washers - Demonstrate that the washers work by spraying the windshield. The Wipers are: Properly Mounted and Secure and operate smoothly. The blades aren't cracked or dry rotten.
• Heater and Defroster - Demonstrate that both the Heater and Defroster are working properly.
• Lighting Indicators - Left Turn, Right Turn, Four Way Flashers, and High Beams.

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. There will also be questions regarding the windshield wipers and free play in the steering wheel.

The Lights And Brakes Section will include questions about dashboard indicator lights, inspecting the parking brakes, and doing a leakdown test on the air brakes. It will also include questions about the low air pressure warning signal and testing your air horn and city horn.

The Suspension And Steering Section will include questions about the tractor protection valve, inspecting the steering box, and inspecting many suspension system parts. It will also include questions about welds being present on tire rims and the minimum tread depth required on steering axle tires.

The Tires And Coupling Devices Section will include questions about shiny trails or rusty threads on lug nuts, inspecting the battery box and cover, and inspecting electrical lines. It will also contain questions about inspecting the coupling devices and the fifth wheel skid plate.

The Emergency Equipment And Fifth Wheel Section will include questions about additional emergeny equipment required by school buses, inspecting the gap between the kingpin apron and the fifth wheel skid plate, and the landing gear securement. It will also contain questions about inspecting driver mirrors and the trailer frame.

The Pre-Trip Inspection: A Practical Guide For the Truck Driver

Updated February 24th, 2022

• Facebook 426
• Pinterest 1

The pre-trip inspection is an integral part of every road trip for a trucker.

It’s probably the most disliked and most often overlooked part of the job of the professional truck driver in the trucking industry.

This inspection is meant to be a thorough check of the truck, trailer and load.

The check is to ensure that everything is in correct working order, prior to the truck and driver, departing on a trip.

Any damage or issues found during the pre-trip inspection which needs attention, must be addressed before departure.

CDL Test Pre-Trip Inspection

 If you just came through the process of getting your CDL, you can breathe a sigh of relief.

You don’t have to check all 500 or so items that you had to memorize for the test every single day.

Out on the road, a thorough pre trip shouldn’t take more than 10 to 15 minutes.

DVIRs – Daily Vehicle Inspection Report

According to federal law ( FMCSR Section 396.11 ), every day, a driver must submit a Daily Vehicle Inspection Report (DVIR) for each power unit he operates. Multiple trailers can go in one report.

DVIRs are either paper or electronic.

Not every trucking company (ahem) enforces this policy, so some truck drivers can go months or years without submitting a DVIR.

Minimum DOT Pre-Trip Inspection Requirements

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

Your trucking company’s DVIR might be more thorough.

This is a thorough Q&A on DVIRs which you can refer to.

Inspecting a New Truck

When you are assigned a new truck (either daily or just once), there are a few additional things you need to check for on the pre-trip inspection.

Truck Compliance

• Cab card and book – This is a book containing the registration, inspection, permits, cab cards, IFTA paperwork, and any other important papers for the truck. Make sure it is in the truck and all the paperwork is up to date.
• Inspection sticker – This is outside the truck. Find it and make sure the truck is not overdue.
• IFTA stickers – These are the fuel tax compliance stickers. They are on both sides of the truck. Make sure the current year is displayed.
• Elog device – Most trucks are required to have a working elog device.
• Required permits – These are in the cab card book. The most common permits are Heavy Motor Vehicle Trip Permit (Oregon) and the Weight Distance Tax Permit (New Mexico).
• New York HUT sticker – This is usually on the front of your truck. It’s a type of permit.
• License plate – Make sure the license plates on the front and back of the truck match.
• FMCSA Safety Regulations and Hazardous Materials book – These will be given to you by your company. They must stay in your truck within arms reach from the driver’s seat.
• Paper logbook – If your e-log stops working, you must log your hours in a paper logbook, which must be kept in your truck.
• Medical card – You must keep your current medical card in your truck. Always have your CDL on you as well.
• Orange triangles – You must have 3 triangles for when you break down.
• Fire extinguisher – Must be charged and secured to the truck. No rolling around on the floor.
• Extra fuses – If your truck doesn’t use circuit breakers, you must have spare fuses.
• Load bars and/or straps
• Extra oil, coolant, and windshield washer fluid
• Line antifreeze and diesel anti-gel
• Chains and bungees
• Gladhand seals
• Hammer, wrench, wire cutters, cable cutters, knife with glass-breaker

The Class A Pre-Trip Inspection Process

Unless I have to bobtail to pick up my trailer, I inspect my truck and trailer together.

The best way to memorize a thorough pre trip is to do it the same way each time.

Your process will look different from mine, but as long as you are consistent, you will be less likely to miss anything.

I do the inspection first thing each morning as well as every time I swap trailers.

Paperwork and Trailer

• Check the paperwork. It should be the first thing checked when you get to your truck.
• Match the trailer number to your paperwork. If your trailer has a seal, make sure it matches too.
• Unsealed trailer. If your trailer does not have a seal, open it and confirm the product matches the bills. If you are picking up an empty trailer, open it and make sure it’s actually empty.
• Confirm your destination. Ensure the destination is the same as on your trip sheet or load assignment. If there is a discrepancy, call your dispatcher.

I personally like to start with checking under the hood of the rig. Not everyone does, but I do.

Under the Hood of the Truck

I walk around the front of the truck, making sure all the lights work. Then I open the hood.

• Fluid levels – Check all fluids: coolant, oil, power steering fluid, and windshield washer fluid. Make sure caps are tight for the rad, oil filler, power steering fluid and the dip-stick is seated properly.
• Alternator, water pump, power steering pump –Make sure these are in good working order, and the belts are not worn or have too much slack.
• Observe at the engine block.  Check for leaks, fluid running down the side of the engine. Check for wear, cracking or fraying. Inspect fan belts for proper tension and signs of wear.
• Hoses – Check all hoses for leaks, cracks, and tears.
• Wiring – Check wiring for wear.
• Steering linkage – Check linkage for worn or missing parts.
• Tires – Tires should be properly inflated and have decent tread. If there are flat spots on the tire, it needs to be replaced.
• Hub seal – Make sure it’s not leaking and wiped with oil if transparent.
• Brakes – Brake chambers should not be out of round and should be free of grease. Shoes should not be worn down too much.
• Slack adjusters – Pull slack adjuster. If it travels more than an inch, it needs to be adjusted.
• Suspension – Shocks should be in good condition, and not covered in grease or oil.

Back of the Truck

Next, I check the back of my truck because it’s easier to check this before hooking to a trailer.

• Tires – Tires should be properly inflated and have decent tread. If the tires have flat spots, the tire needs to be replaced.
• Suspension – Shocks and airbags should be in good condition, and not covered in grease or oil.
• Drive shaft – Driveshaft should be undamaged and free of grease. Make sure there is no debris in the u-joints.
• Frame – The frame should not have any welds and not cracked or significantly rusted.
• Fifth wheel – The fifth wheel should be properly greased and not broken.
• Fuel tanks – Fuel tanks should not be leaking.
• Stairs and catwalk – Stairs and catwalk should be free of debris and not broken.

Tires should be checked with a tire gauge.

Tip . This is especially if you are slip seating. Tire thumpers aren’t very accurate. If you use a tire thumper, still check with a tire gauge from time to time.

Drives and tandems should be inflated to 100-110 psi and have a minimum tread or 2/32in. Steer tires should be inflated to 110-120 psi and have a minimum tread of 4/32in.

Tires under 50 psi should be replaced, as they can’t retain enough air pressure.

Flat spots can occur from dragging tandems in the winter or when trying to slide the tandems. Tires with flat spots should be replaced.

Check tires for damage, nails, and punctures.

Next, I jump in my cab and start my truck.

• Gauges – Make sure air, oil, and water temperature gauges rise to normal levels.
• Mirrors – Adjust mirrors before moving your truck.
• Windshield wipers – Make sure they work and sit flat against the windshield.
• Horn – Make sure the city and air horns both work.
• Heat and A/C – Check to see if heat and/or air conditioning is working.
• Seat belt – Seat belt should not be frayed and should move freely.

Coupling and Air Lines

This is what could happen if you don’t do the tug test.

The pre-trip inspection is a pretty important thing to do.

Learn your pre-trip procedure and do it when required.

This is why you should always do a tug test when picking up a trailer. The passenger side of the front of the trailer is resting on the frame of the truck and NOT hooked up to the 5th wheel.

The front left corner of the trailer is supported by retracted landing gear only. (Not good!)

The truck driver in this photo (hopefully) learned how critical a pre-trip is. Don’t end up in a pickle like this guy.

Next, I hook up to my trailer.

• Tug test – I back under my trailer until I hear a click, and then immediately do a tug test.

A tug test tests both your coupling and your brakes. If you pull away from your trailer, you aren’t hooked properly.

If you pull your trailer with you, your trailer brakes are out of adjustment. Be absolutely sure to write it up and have it corrected before departure.

• 4 Ways + Headlights. I also turn on my four-way flashers and headlights.
• Airlines and pigtails – Next, hook up airlines and pigtails (electrical connection). Inspect to make sure they aren’t leaking or ripped.
• Visual check of Fifth wheel – Look at the fifth wheel arm under the trailer to make sure it is coupled. The arm should be in.
• Landing gear – Raise the landing gear and check for damage.

Next, I check the bulkhead (front of the trailer).

• Wall – Make sure the wall is not damaged.
• Inspection sticker – Check the DOT inspection sticker to make sure it’s not out of date.
• Registration paperwork – Check the front trailer box to make sure the registration is good.
• Reefer unit – If you are pulling a reefer, select the pre trip function on the unit and run it. It should be completed by the time you are finished your pre trip inspection.

Next step for the pre-trip inspection is to check the side of the trailer and the tandems.

• Lights – Lights should be on and flashing.
• Suspension – springs or airbags should be in good condition, and not covered in oil or grease.
• Tandem pins – Tandem pins should be locked in position, and slider arm should be in its cradle.
• Cables – Make sure the tandem cables aren’t dragging on the ground.
• Underbelly – Make sure there are no damaged beams under the trailer. Check the entire length.
• Mudflaps – Mud flaps should not be torn and hanging.

Back of Trailer

Next, I check the back of the trailer.

• Doors – Doors and hinges should not be damaged.
• Door latches – Doors should be closed and secured.
• Seal – Seal should be intact and match paperwork.
• DOT bumper – DOT bumper should not be damaged
• License plate – Check for the license plate. They tend to wear out and fall off.

Passenger Side

Next, I check the passenger side.

• Brakes – Brake chambers should not be out of round and should be free of grease.
• Suspension – Springs or airbags should be in good condition, and not covered in grease or oil.
• Mudflaps – Mud flaps should not be torn.

Ready to Roll

Finally, I jump in my truck and double check my paperwork and destination.

I release my air brakes, roll forward, and push the service brake.

If everything is good, I’m ready to roll.

Post-Trip Inspection

When I’m done for the day, and every time I swap trailers, I do a post-trip inspection. If I am swapping trailers, I do a pre-trip on the new trailer as well.

A post-trip includes:

• lowering the landing gear
• removing the airlines
• uncoupling, and walking around the trailer checking tires, lights, seal, and mudflaps

Then I finish my paperwork and go home.

Slip Seating

If you slip seat (meaning you are in a different truck each shift), your pre- trip check should be more thorough than if you are permanently assigned a truck.

This also applies to the first inspection after being assigned a truck.

Please be courteous and write up any problems or issues found, so the next driver of the vehicle doesn’t have to deal with it.

Side Note: Clean out your truck and throw away any trash. Common courtesy goes a long way in trucking, between drivers.

Pre-Trip Inspection F.A.Q.

Most breakdowns can be avoided with proper preventative measures, such as daily inspections.

Thorough inspections should be done at the start of each shift. Inspections of trailers should be done every time you swap trailers.

Each driver should do a thorough pre-trip every time they swap drivers.

It should take about 10-15 minutes to perform a pre trip inspection.

The DOT. Make sure you stay in compliance so you don’t end up with hefty fines and an out of service.

The best way to memorize your pre trip inspection routine, is to do it the same way every time. That way you’re less likely to miss something. If you have questions, ask your safety team at your company.

Fluids in the engine, engine hoses and wires, brakes and suspension, mudflaps, trailer registration and inspection paperwork, and license plates.

A Few Trip Planning Tips

• Buy and learn to read a trucker’s atlas. It’s useful to plan routes and avoid restricted roads. I find this road atlas a necessity as a professional truck driver.
• Buy a decent trucking GPS , but don’t rely on it 100%. Use common sense.
• Don’t use the GPS in your elog device. It will put you in a lake.

Please note that minimum requirements for the inspection are established by the FMCSA.

But these may vary by state, trucking company, truck type, and trailer type.

It is your duty as a professional truck driver to perform a thorough pre-trip inspection before each trip and before you drive.

You’ll save yourself from headaches, fines and unnecessary accidents.

Embarking on a safe and efficient journey as a truck driver begins long before hitting the road. The cornerstone of every successful trip is a thorough pre-trip inspection. This guide delves into the essential aspects of a pre-trip inspection checklist. These critical checkpoints can make all the difference in your driver’s safety and the efficiency and success of the journey.

What is a pre-trip inspection?

A pre-trip inspection is a proactive measure taken by truck drivers to ensure their vehicles are in optimal condition and adhere to safety standards and other relevant regulatory requirements. This assessment checks for signs of wear, damage or malfunction on critical components like the engine, brakes, lights, tires, fluid and more.

The goal of a pre-trip inspection is two-fold: safety and compliance . A thorough vehicle examination helps identify potential issues so they can be addressed promptly, minimizing the risk of breakdowns and accidents. The inspection is crucial for compliance with industry regulations and standards. Failure to do so could result in fines, penalties or suspensions.

The importance of a pre-trip inspection

Pre-trip inspections are more than a regulatory requirement; they can help keep drivers and the public safe, maintain cargo integrity and improve vehicle longevity. Here’s why this practice is essential:

• Enhanced safety: Identifies potential mechanical issues before they escalate. This means reduced risk of breakdowns and roadside emergencies.
• Improved efficiency: Addresses issues before they happen on the road to ensure fleets deliver on time.
• Better compliance: Helps meet legal requirements, avoid unnecessary fines and penalties and comply with industry standards and safety protocols.
• Protected cargo: Ensures cargo is secure and adequately loaded, preventing damage during transit.
• Maintain equipment health: Identifies wear and tear on components, allowing for timely maintenance, reducing long-term repair costs and prolonging the longevity of the vehicle and its critical systems.
• Boosted reputation: Demonstrates a commitment to professionalism and responsibility. This enhances a fleet’s reputation and builds stronger customer relationships.
• Driver confidence: Following a standardized pre-trip inspection checklist reassures drivers that their truck is in optimal condition.

Main components of a pre-trip inspection checklist

To ensure drivers cover all the essential components of pre-trip inspections, here are the main checkpoints to keep in mind:

Tire inspection

• Tread depth: Measure tire tread depth . Inadequate tread depth can compromise traction and vehicle stability, especially in unfavorable road conditions.
• Tire inflation: Verify that all tires meet the manufacturer’s specifications. Improper inflation poses safety issues and can lead to uneven wear and reduced fuel efficiency.
• Visible tire damage: Inspect each tire for cuts, bulges or other visible damage. Address these issues promptly to prevent blowouts and other safety concerns.
• Valve stem integrity: Inspect valve stems for damage or leaks and ensure caps are in place. Damaged stems can lead to pressure loss.

Lights and reflectors

• Headlights: Ensure both high and low beams work. Check for proper alignment to maximize visibility without blinding other drivers.
• Taillights: Verify that taillights work, including brake lights and turn signals.
• Clearance lights: Ensure clearance lights work. These enhance the visibility of the vehicle’s dimensions, especially in low-light conditions.
• Reflectors: Confirm the presence and condition of reflectors on all sides of the vehicle.
• Hazard lights: Ensure hazard lights work.
• Turn signals: Ensure the turn signals work on both sides.

Brake check

• Air brakes: Check air brakes for leaks by listening for hissing sounds. Confirm that air pressure builds within a reasonable time after starting the engine.
• Parking brake: Test the parking brake to ensure it holds the vehicle securely.
• Brake fluid levels: Check the fluid reservoir for proper fluid levels. Low levels may indicate a leak or wear.
• Brake pads and shoes: Inspect brake pads and shoes for visible wear. They may need replacing if they are too thin or show uneven wear patterns.
• Brake drums and rotors: Examine brake drums and rotors for signs of scoring, grooves or heat-related damage.
• Brake lines and hoses: Pay attention to visible damage, corrosion, bulging or leaks.
• Anti-lock braking system: Check the dashboard for warning lights.

Engine compartment

• Engine oil: Check the engine oil level. Ensure it falls within the recommended range.
• Coolant: Ensure the coolant reservoir has the appropriate amount to prevent engine overheating.
• Drive belts: Examine for signs of wear, fraying or cracking.
• Hoses: Inspect hoses for leaks, bulges or soft spots. Replace any damaged hoses to prevent leaks.
• Battery: Check battery terminals for corrosion and ensure they’re securely connected. Loose or corroded connections can lead to electrical issues.
• Air compressor: Inspect the air compressor for visible damage and ensure proper functioning for optimal brake performance.

Frequently Asked Questions

When should a driver perform a pre-trip inspection.

A driver should perform a pre-trip inspection before embarking on each journey. This proactive examination of the vehicle’s mechanical and safety components ensures it’s in optimal condition for the road. Conducting an inspection daily or before the start of each trip is a regulatory requirement in many jurisdictions. Plus, it can enhance driver safety, limit the risk of mechanical failures and contribute to overall road safety.

What is the first step of the pre-trip inspection?

The first step of a pre-trip inspection should involve an external assessment of the truck or commercial vehicle. This includes visually inspecting the vehicle’s overall condition, ensuring no visible defects or safety hazards. Start with a walkaround to identify any significant issues. Then, break the inspection down into components. For example, start with the tires, then move on to the lights, brakes, mirrors, and under the hood.

What is the most overlooked part of pre-trip inspection reports?

Drivers may focus on more visible components, like tires and lights, neglecting critical elements like brake lines, suspension and the exhaust system. Checking for signs of leaks, loose parts, or damage underneath the vehicle is crucial for identifying hidden issues that could compromise safety and performance. Completing every part of the checklist ensures a comprehensive assessment, reducing the risk of overlooking these critical components.

What happens if I don’t perform the inspection?

Failing to perform a pre-trip inspection can have serious consequences, both legally and in terms of safety. Regulatory bodies often mandate these inspections, and non-compliance can lead to fines, penalties or even the suspension of driving privileges.

Beyond legal implications, neglecting the inspection jeopardizes safety. Without identifying potential issues before hitting the road, there’s an increased risk of mechanical failures, accidents, and breakdowns, posing a danger to the driver and others on the road.

Additionally, failure to perform pre-trip inspections may impact insurance claims and the overall reputation of the driver and transportation company.

What is a DOT pre-inspection checklist?

A DOT pre-inspection checklist is a comprehensive list of items and components that commercial vehicle drivers must inspect before embarking on their trip, as mandated by the United States Department of Transportation (DOT).

Where should the ignition key be during the pre-trip inspection?

During a pre-trip Inspection, the ignition key should be in the “off” position. This is a standard safety practice to prevent accidents during the inspection. Keeping the ignition key off allows the driver to thoroughly examine various components without the risk of moving parts or unexpected vehicle movement. This includes checking the vehicle’s lights, brakes, tires and other essential elements. It’s a precautionary measure that promotes the safety of the driver and those in the vicinity during the inspection process.

How long should a pre-trip inspection reports take?

The duration of a pre-trip Inspection can vary depending on factors such as the driver’s familiarity with the vehicle, the complexity of the truck itself, and the thoroughness of the inspection. On average, a comprehensive pre-trip inspection typically takes around 15 to 45 minutes.
