CHP Inspection Checklist Header

Follow this checklist to help maintain your equipment and keep it in compliance with DOT inspection requirements. The checklist is tailored to tow companies for the California Highway Patrol inspection program but can also be used as a guide for general commercial vehicle and tow truck inspections. Most categories include links to the replacement parts if the original parts are found to be defective. Truck inspections make a difference, and whether you are prepping for the California Vehicle Code Inspection or your state’s annual vehicle inspection certification, this checklist is the first tool you need to reach for to ensure compliance for your fleet.
