CDL Pre-Trip Inspection Checklist & Guide

Download the CDL Pre-Trip Inspection Checklist (PDF)

 

A CDL pre-trip inspection is a crucial part of safely operating a commercial vehicle. It’s also required by the Federal Motor Carrier Safety Administration.

Use this guide as a memory aid ONLY. Every company’s pre-trip inspection varies, as do pre-trip inspection tests administered as part of formal CDL training.

 

 

 

 

 

Checking the vehicle before driving each day normally takes about 15 minutes.

 

When inspecting any vehicle component:

Check that it’s properly secured and mounted, not cracked or broken, and has no visible leaks.

 

When inspecting any belt:

Check that it doesn’t have excessive play, and no splits or cuts.

 

When inspecting any fluid reservoir:

Check dipstick locations and that all fluids are at proper levels.

 

When inspecting any hose:

Check that there are no splits or cuts, and no leaks. Check that it’s secure at both ends.

 

When inspecting any metal part:

Check that it’s securely mounted and not broken or cracked. Check that there are no illegal welds.

 

When inspecting any rubber part:

Check that there are no abrasions, bulges, or cuts.

 

 

 

 

 

 

Before you begin the inspection:

  • Check VIN, insurance, and registration to make sure you’re inspecting the right vehicle
  • Select a safe location on level ground and a clear view away from other vehicles.
  • Keep the key in your pocket
  • Use wheel chocks before going under any part of the vehicle
  • Wear a high-visibility vest, gloves, and eye protection

 

 

 

  • Are the lights on the front of the vehicle securely mounted, clean, and intact?
  • Are there any leaks under the vehicle?
  • Is the vehicle leaning or sagging?
  • Is there any visible damage to the vehicle?
