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
• 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.

Pre-Trip Inspection Checklist - Class A

Our pre-trip inspection checklist covers every part of the truck from front to back, both inside and outside of the truck. It covers the air brakes, suspension parts, steering components, wheels and rims, fuel tanks, batteries, lights, and more. It also covers the air brake tug test and checks for everything under the hood including alternator, water pump, fuel pump, fluids, and more.

This is a super handy checklist to study anytime you have a few minutes to spare:

Best Free CDL Pre-Trip Inspection Checklist | Trucker Safety & Profit

Table of Contents

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

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

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

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

Why Following the CDL Pre-Inspection Checklist is So Important

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

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

General Tips Throughout Your Pre-Trip Inspection

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

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

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

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

PFL: Peak for leaks in fluid and air containers.

PMS: Are bolts properly mounted and secure?

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

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

What are the ABCS in a pre-trip inspection?

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

How Long Should a Proper CDL Checklist & Inspection Take?

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

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

Standard cdl pre trip inspection checklist.

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

A few exam tips before the pre-trip checklist:

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

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

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

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

▢ Alternator: securely mounted, belt in good shape

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

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

If Left Unchecked:

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

▢ Brake Pads: ¼ minimum brake pad thickness

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

▢ Brake Chamber : no audible leaks or visible damage

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

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

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

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

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

▢ Reflector Tape: clear, free of dirt

If Left Unchecked:  

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

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

▢ Wheel inside: not broken, no illegal welds

▢ Wheel outside: no cracks or illegal welds

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

▢ Spacing: duals are properly spaced

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

▢ Lug Nuts: present, tight, no cracks

▢ Hub Seal: not cracked or loose

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

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

Steer Axle/Rear Suspension

▢ Steering Shaft: not BBC, securely mounted

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

▢ Hose: no visible leaks, properly mounted

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

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

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

▢ Spring Mounts: not BBC, securely mounted

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

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

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

If Left Unchecked: 

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

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

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

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

▢ Foot Pedals: unobstructed

▢ Horns: functioning properly

▢ Windshield: no stickers, cracks, or excessive dirt

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

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

▢ Steps: mounted and secured

▢ DEF cap: secured

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

▢ Skirting: no damage, panels secure

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

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

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

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

▢ Universal joint: not BBC

▢ Differential: no leaks

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

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

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

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

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

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

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

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

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

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

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

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

▢ Clearance lights: not loose, cracked, or dirty 

▢ Top rail: No cracks or collision damage.

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

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

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

▢ Floor: no holes

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

▢ Tandem release: properly mounted and secured, not BBC

▢  Slide rail: properly mounted and secured, not BBC

▢  Pins: engaged

▢ Clearance lights: not cracked or dirty

▢ Doors: not broken, no holes, seal intact

▢ Hinges:   securely mounted, not BBC

▢ Door handles and rods: securely mounted, functioning properly

▢ Lights: securely mounted, not cracked or dirty

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

▢ Bumper: properly secured, not BBC

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

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

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

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

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

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

▢ Voltmeter: operational, 13 - 14 volts

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

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

▢ Tachometer: 1000-1500

▢ Water temperature: 180-205 degrees

▢ Def level: minimum of one light bar

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

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

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

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

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

Most Common Issues Found During Pre Trip Inspection

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

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

Broken Lights

What to Do:

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

How to Avoid This:

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

Maintenance as a Money Saver:

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

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

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

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

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

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

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

• power steering
• water leaks
• brake fluid

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

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

Maintenance as a Money Saver: 

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

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

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

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

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

Overheating

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

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

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

Our trucking dispatch software is completely free and feature-rich, saving teams time on paperwork and document sharing. The platform integrates seamlessly with the driver app simplifying everything from load finding to billing.

• Load board syncing cuts down the time it takes to book a load

Bypass Construction

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

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

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

Weather Apps

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

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

Truck Parking

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

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

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

Dock Details

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

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

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

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

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

Legally Bypass Inspection Sites

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

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

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

Health Apps

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

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

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

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

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

How to Remember Pre Trip Inspection CDL Checklist

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

BBC: Bent, broken, or cracked

ABC: Abrasions, bruises, cuts

PFL: Peak for leaks

3 L's: Lights, leaks, leans

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

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

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

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

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

CDL Class B Pre Trip Inspection

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

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

New Truck Pre-Inspection Checklist Addition

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

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

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

Final Notes on Completing Your CDL Pre-Trip Inspection Checklist

So, you're armed with the ultimate CDL pre trip inspection checklist that will help you pass your exam and save on vehicle maintenance.

Complete pre-trip inspection checklist for truck drivers

By The Schneider Guy

Estimated reading time: 4 minutes  

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

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

What is a pre-trip inspection?  

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

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

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

In order to learn how to take a CDL license test, you need to find reliable real CDL test questions & answers.  We have the actual Texas CDL questions & answers to all of the written CDL tests at your local TXDPS driver license office.

How to take the test

Before you take your CDL license test, you will want to review your CDL information.  All TXDPS testing centers offer a CDL booklet for you to study. You should read the Texas Commercial Vehicle Handbook on each subject before practicing testing a couple of times to learn the information, then practice what you have learned on our online testing.

Depending on how well you did on your first few online testing practices, you may want to redo the test 10 to 15 times after reviewing the information.  This will help you to remember what the correct answer is.  Our CDL testing program will keep making you review the questions that you got wrong to help yourself learn what the correct answers are.

Keep in mind that many practice tests online that are free and nothing good is free. You will have to pay for access to the real Texas CDL test questions.  Because of this, you should get comfortable with taking the test before going in for the real thing at your local TXDPS office.  Using our online testing, you will not waste your time, time off work, miles on your car and money on fuel taking a test that you aren’t ready for. There is nothing more frustrating than going into the driver license office waiting a long time in line and failing missing 1 to many questions.

Where do you begin ???

To begin you will have to obtain a CDL Permit. The following two tests, Texas Commercial Vehicle Operation and Combination , are the very first two tests you will have to take to get a class A Permit. You will take Texas Commercial Vehicle Operation first whether you are getting a class A, B or C CDL Permit. To get a class B or C CDL permit you will only need to take one test, the Texas Commercial Vehicle Operation . If doing a class A CDL you will take the Combination written test second to obtain a class A CDL Permit.

Depending on whether you are wanting a class A, B or C CDL license you will need to pass one or if not all of these written tests at your local TXDPS office before scheduling a CDL road test. You must take these written tests in this order at the TXDPS office.

There are 725 questions total that can be asked on all of the class A CDL tests. Our testing program is set up just like your local TXDPS computer. When you practice with our online testing these are the exact CDL questions and answers you will see when you sit down to take the CDL tests at your local TXDPS office.

Again, our CDL test questions and answers are exactly what you will see, word for word, at your local TXDPS driver license office.

TXDPS – CDL WRITTEN TESTS:

Here are the five CDL written tests you will have to complete to advance on to the road test with a TXDPS examiner. The written tests you will have to complete are highlighted in bold. Written tests must be taken in this order at any TXDPS office:

       1. TEXAS COMMERCIAL VEHICLE OPERATION - (The first test you will take to obtaining a permit)            20/16 (questions asked / must get right – there are a 80 possible questions )

       2. COMBINATION - (The second test you will take in obtaining a permit)            20/16 (questions asked / must get right - there are a100 possible questions )

Once you obtain a permit with passing the Texas Commercial Vehicle Operation & Combination tests then you may take any of the following tests in any order at any TXDPS office.

      3. GENERAL KNOWLEDGE           50/40 (questions asked / must get right - there are a 250 possible questions )

      4. AIR BRAKES           25/20 (questions asked / must get right - there are a 100 possible questions )

      5. PRE – TRIP INSPECTION           30/24 (questions asked / must get right - there are a180 possible questions )

SPECIAL NOTE: You do not have to take all of the written tests at the same TXDPS office. You may take written tests at different locations. You can also take a road test at a totally different TXDPS office where you did not take your writtent tests at. The TXDPS have all of your tests on computer and every driver license office in the State of Texas can see the written tests you have taken and your test scores. It is a good idea to get a receipt for each written test taken. The TXDPS driver license office has a new computer system that can generate a receipt for each written test you take. You have to ask for the receipt from the TXDPS counter employee assisting you. If the TXDPS counter employee does not know what you are asking for or how to find the receipt, ask to speak to the TXDPS unit supervisor. ALWAYS get a receipt for each test you take. Remember the TXDPS employees are goverment workers who make mistakes daily. You do not want to take a test and it get lost from a lazy TXDPS worker by not placing the completed test into the TXDPS system on your driver license showing being not completed under your license number.

How do you know when you are ready to go to the TXDPS office to test?

We recommend once you are scoring 90% or higher back to back a minimum of 10 up to 15 times in a row on our website's online testing program, on one test subject, then you are ready to take the test at your local TXDPS office. You must score 80% or higher at the TXDPS office on their computer to pass.

Common Mistakes to Avoid When Conducting a Pre-Trip Inspection as a CDL Holder

As a commercial driver’s license (CDL) holder, conducting a thorough pre-trip inspection is crucial to ensure the safety of yourself, your cargo, and other road users. A pre-trip inspection involves carefully examining various components of your vehicle to identify any potential issues before hitting the road. However, many CDL holders make some common mistakes during this process that can compromise safety and result in costly breakdowns or accidents. In this article, we will highlight these mistakes and provide you with tips on how to avoid them.

Neglecting to Follow a Checklist

One of the most common mistakes CDL holders make during a pre-trip inspection is neglecting to follow a checklist. A pre-trip inspection checklist is designed to guide you through each step of the process, ensuring that no component or system is overlooked. By not using a checklist, you run the risk of missing critical areas that could lead to mechanical failures or violations during roadside inspections.

To avoid this mistake, create or obtain a comprehensive pre-trip inspection checklist specific to your vehicle type and adhere to it diligently before every trip. This will help you establish a routine and ensure consistency in inspecting all necessary components.

Rushing Through the Inspection

Another mistake often made by CDL holders is rushing through the pre-trip inspection process. It’s understandable that time constraints can be challenging, especially when facing tight schedules or deadlines. However, sacrificing safety for speed can have severe consequences.

To avoid rushing through your pre-trip inspections, allocate sufficient time for this essential task in your schedule. Plan ahead and allow for extra time if needed so that you can thoroughly inspect all components and systems without feeling rushed.

Overlooking Small Details

While inspecting major components like brakes and tires is crucial, overlooking small details can also lead to significant problems down the road. CDL holders often make the mistake of neglecting minor issues such as loose bolts, worn-out windshield wipers, or broken mirrors.

To avoid this oversight, pay attention to even the smallest details during your pre-trip inspection. Take your time to inspect all areas of the vehicle, including the interior and exterior. Make a habit of reporting any minor issues to your maintenance department promptly.

Failing to Document Inspection Results

Documentation is an essential part of a pre-trip inspection as it serves as evidence that you have conducted a thorough check before starting your journey. Many CDL holders make the mistake of overlooking this crucial step, assuming that their word alone will be sufficient if questioned during a roadside inspection.

To avoid this mistake, create a system for documenting your pre-trip inspections. This can be as simple as using a checklist with spaces for notes or taking photos and keeping them in a dedicated folder on your phone or computer. By having documented proof of your inspections, you can demonstrate your commitment to safety and compliance if ever required.

In conclusion, conducting a pre-trip inspection is an essential responsibility for CDL holders. By avoiding common mistakes such as neglecting checklists, rushing through inspections, overlooking small details, and failing to document results, you can ensure that your journeys are safe and free from unnecessary breakdowns or violations. Remember, safety should always be the top priority when operating commercial vehicles on our roads.
