Hello TT! You're looking at yet another legendary thread done by me!

This is my Pre-Trip Inspection , done my way! This Pre-Trip is done on my truck and trailer. I physically took the pictures and edited them to my liking. These are not pictures taken off of Google. It is a complete Pre-Trip Inspection and features everything you'll need to know. I've been working on this for a long time and my hometime finally gave me the chance to finish it all up.

This is based off of Prime Inc.'s Pre-Trip Inspection procedure. Your companies Pre-Trip might vary slightly.

Here are our sections:

Engine Compartment

Drivers Door Fuel Area

Coupling System

Trailer (Please note in the type of suspension your trailer has)

Light Check

In-Can Inspection and Brake Tests

You will absolutely have to do the Coupling System, Light Check, and In-Cab Inspection. Then they select for you to also do either the Engine Compartment, Drivers Door Fuel Area, or the Trailer. It could be either one. You will have a total of 4 sections that you must pass on your exam. So study extra-hard on those required sections.

As stated, these are solely based off of how I like to do the Pre-Trip. I give my personal opinions as well as some helpful tips.

Your Instructors advice may vary. In the end, just do it the way your Instructor wants you to do it.

Pre-trip Inspection:

A pre-trip inspection is a thorough inspection of the truck completed before driving for the first time each day.

Federal and state laws require that drivers inspect their vehicles. Federal and state inspectors also may inspect your vehicles. If they judge a vehicle to be unsafe, they will put it “out of service” until it is repaired.

Drag Link-

Properly Mounted and Secure. Not Cracked, Bent, or Broken.

Daniel's Tip: Combine the Pitman Arm, Drag Link, Tie Rod, Castle Nuts and Cotter Pins and state that you'll be checking all of these the same way.

truck driver's pretrip inspection tie rodCaste Nuts and Cotter Pins-

None missing. Cotter Pin is present.

Daniel's Tip: Lot's of folks like to combine this with the Drag Link. I do not, I like to say this separely at the very end of my Steering Section. As long as you say there are none missing and the Cotter Pin is present you'll be good to go! Don't forget that there are three Castle Nuts and you must point at all three.

truck driver's pretrip inspection caste nuts and cotter pinsSpring Hanger-

Properly Mounted and Secure at both front and rear. Not Cracked, Bent, or Broken.

Daniel's Tip: The difference between a Hanger and a Mount is that Hangers are much, much smaller. I could go technical but don't over complicate this. The Hangers are in the front, Mounts in the back. Be sure to say "at both front and rear".

truck driver's pretrip inspection spring hangerLeaf Springs-

Properly Mounted and Secure at both ends. Not Cracked, Bent, or Broken. None are shifted.

Daniel's Tip: Leaf Springs will always be in the Engine Compartment, they're not Spring Arms! Don't let any fool tell you that because they would be wrong. These are Leaf Springs because there are multiple Springs - plural. Be sure to say none are shifted.

truck driver's pretrip inspection leaf springsU-Bolts-

Properly Mounted and Secure. Not Cracked, Bent, or Broken. None missing.

Daniel's Tip: Very simple item. Just be sure to say none are missing, that line is easily forgettable.

Properly Mounted and Secure at both ends. Not Cracked, Bent, or Broken. Not leaking.

Daniel's Tip: Don't forget to say "at both ends" and "not leaking". If it'll leak, it'll leak at the point where the top and bottom portion of the Shock meet - in the Middle.

truck driver's pretrip inspection shock absorberBrake Hose-

Properly Mounted and Secure at both ends. No Abrasions, Bulges or Cuts. Not leaking air.

Daniel's Tip: Again, don't forgot to say "at both ends". The Hose is rubber so give it the ABC and not leaking air. You could combine the line with the Chamber but I prefer not to but its very easy to forget to mention the hose. When you're under pressure, you tend to forget the small things - like a hose.

truck driver's pretrip inspection lug nutsHub Seal-

Properly Mounted and Secure. Not Cracked, Bent, or Broken. Not leaking and filled to manufactures specifications.

Daniel's Tip: My method is that the Hub Seal is located on the Steer Axle, Axle Seal belongs on all the other Axles. Though it doesn't matter if you call the Trailer Axle a Hub Seal. You can call these Hub or Axle Seals. Just be sure to say that its filled to manufactures specifications.

truck driver's pretrip inspection hub sealSteer Tire-

No Abrasions, Bulges or Cuts to the tread or sidewalls. Tread depth is no less than 4/32 of an inch. Properly filled to manufactures specifications. Check it with an air gauge.

Daniel's Tip: Tires are a big deal! Be sure to look for Abrasions, Buldges or Cuts to the Tread and Sidewalls. Be sure to say it too. Steer tires cannot be less than 4/32 of an inch depth. You must say "of an inch", simply saying "4/32" is not enough. Properly filled to manufactures specifications and you absolutely must add that you check it with an air gauge! You don't have to physically check it with an air gauge on your exam, just mention that you would.

You must say "of an inch", simply saying "2/32" is not enough. Properly filled to manufactures specifications and you absolutely must add that you check it with an air gauge!

Mudflap-

Properly Mounted and Secure. Not Cracked, Bent, or Broken.

Daniel's Tip: Simple item. Just a sidenote, don't forget the Reflective Tape on your Mudflap when you do your Light Test.

truck driver's pretrip inspection mud flap

Spacing-

Only if you're truck is equipped with duals! Check to see that there is proper space between the tires. There is nothing stuck between the tires.

Daniel's Tip: This only applies if you don't have Super Singles. Just let the examiner know you would check for proper space between the tires and making sure there's nothing stuck between them.

truck driver's pretrip inspection spacing between tires

Super Singles:

A single, wide wheel substituted for a tandem (two wheel) assembly. The main benefit of a super single is a reduction in weight and lower rolling resistance which provide better fuel economy. The disadvantage is the lack of tire redundancy (or a 'backup tire' in case of a blowout) from which tandem wheels benefit. A tire blowout is more dangerous with a super single and can not be driven on.

Coupling Area

Electric Line-

Properly Mounted and Secure at both ends. No Abrasions, Bulges or Cuts. No exposed wires.

truck driver's pretrip inspection apronSkid Plate-

Properly Mounted and Secure. Not Cracked, Bent, or Broken. Properly lubed.

Daniel's Tip: The Skid Plate is the top slippery surface of the Fifth Wheel. It must be properly lubed.

truck driver's pretrip inspection skid plateGap-

Check to make sure that there is no space between the Apron and Skid Plate.

Daniel's Tip: The Gap is not an actual item. Its the space between the Apron and the Skid Plate. There should be no daylight between the Apron and Skid Plate.

truck driver's pretrip inspection gap between apron and skid plateKing Pin-

Properly Mounted and Secure. Not Cracked, Bent, or Broken.

Daniel's Tip: Can be easy to miss because you can't see it. But please don't miss something so important as the King Pin. Engrave this into your head.

truck driver's pretrip inspection king-pinLocking Jaws-

Properly Mounted and Secure. Not Cracked, Bent, or Broken. Fully locked around the King Pin.

Daniel's Tip: On your exam you must bend down and physically check those Locking Jaws, just like you should be doing every day several times. Be sure to say its fully locked around the King Pin.

truck driver's pretrip inspection locking jawsPlatform-

Properly Mounted and Secure. Not Cracked, Bent, or Broken.

Daniel's Tip: The Platform is what the Fifth Wheel rests on. It goes Frame, then Platform, then Fifth Wheel. The Platform is easy to inspect, feel free to combine it with the Mounting Bolts. But again, I choose not to.

truck driver's pretrip inspection 5th wheel platformMounting Bolts-

Properly Mounted and Secure. Not Cracked, Bent, or Broken. None missing.

Daniel's Tip: Technically, you could combine this with the Platform but I choose not to. Up to you. Be sure to point at the bolts and don't forget to say none missing.

Properly Mounted and Secure. Not Cracked, Bent, or Broken. Is in the fully locked position.

Daniel's Tip: Remember to point at the Sliding area and the Locking Pin. It must be in the fully locked position. You must say that!

truck driver's pretrip inspection sliding 5th wheel locking pinClearance-

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

Daniel's Tip: Clearance is by far the easiest to forget of everything in the entire test! I kid you not. Please engrave this into your head. You want to check the space between your mudflap and landing gear, so they don't hit each other on a turn.

Properly Mounted and Secure. Not Cracked, Bent, or Broken. No missing Cross Members.

Daniel's Tip: The Frame is the bottom portion on the walls of the trailer. Don't get that mixed up. The Cross Members go side-to-side throughout the trailer, there cannot be any missing.

Properly Mounted and Secure. Not Cracked, Bent, or Broken. Release handle and locking pins are in the fully locked position.

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.

Daniel's Tip: The Slack Adjuster and Push Rod are always combined. Please, be very careful with your words on this one. Say it exactly how I wrote it! Memorize that line. The ones in the back look a lot different than the ones on the Steer axle, but that shouldn't impact you on your performance.

Tandems:

Tandem Axles

A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".

A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".

Rim-

Properly Mounted and Secure. Not Cracked, Bent, or Broken. No unauthorized welds.

Daniel's Tip: Fairly simple item. Be sure to mention that there cannot be any unauthorized welds.

No Abrasions, Bulges or Cuts to the tread or sidewalls. Tread depth is no less than 2/32 of an inch. Properly filled to manufactures specifications. Check it with an air gauge.

Daniel's Tip: Tires are a big deal! Be sure to look for Abrasions, Buldges or Cuts to the Tread and Sidewalls. Be sure to say it too. Trailer tires cannot be less than 2/32 of an inch depth. You must say "of an inch", simply saying "2/32" is not enough. Properly filled to manufactures specifications and you absolutely must add that you check it with an air gauge! You don't have to physically check it with an air gauge on your exam, just mention that you would.

Properly Mounted and Secure. Not Cracked, Bent, or Broken.

Daniel's Tip: Simple item. Just give it a PMS and a CBB.

Only if you're truck is equipped with duals! Check to see that there is proper space between the tires. There is nothing stuck between the tires.

Daniel's Tip: This only applies if you don't have Super Singles. Just let the examiner know you would check for proper space between the tires and making sure there's nothing stuck between them.

Properly Mounted and Secure. Not Cracked, Bent, or Broken. Opens and close and latches properly. Door seals are not worn, torn, or dry rotted.

Daniel's Tip: You don't need to open the trailer doors to demonstrate that they open and close and latch properly. So keep that in mind. Just be sure to point out the Hinges and the Door seals and say the above.

Super Singles:

A single, wide wheel substituted for a tandem (two wheel) assembly. The main benefit of a super single is a reduction in weight and lower rolling resistance which provide better fuel economy. The disadvantage is the lack of tire redundancy (or a 'backup tire' in case of a blowout) from which tandem wheels benefit. A tire blowout is more dangerous with a super single and can not be driven on.

Light Check

Five locations that you must check your lights are:

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 are:

Left Turn Signal

Right Turn Signal

Four Way Flashers

High Beams/Low Beams

Brake Lights

--------When you start your Light Check, you should tell the examiner

that you will check all your:

Lights, Reflectors, Reflective Tape the same way.

Properly Mounted and Secure

Not Cracked, Bent, Broken

Clean and illuminated

The proper color of amber to the front and sides, and red to the rear.

Turn 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.

TruckingTruth was founded by Brett Aquila (that's me!), a 15 year truck driving veteran, in January 2007. After 15 years on the road I wanted to help people understand the trucking industry and everything that came with the career and lifestyle of an over the road trucker. We'll help you make the right choices and prepare for a great start to your trucking career.
