What is a DVIR?
A DVIR is a Driver Vehicle Inspection Report, a formal report whose purpose is to confirm the completion of a commercial motor vehicle (CMV) inspection by its driver, as required under 49 CFR 396.11 and 396.13 of the Federal Motor Carrier Safety Regulations.
Per 49 CFR 396.11, a driver must conduct a post-trip inspection of each vehicle they operate at the end of the day. Any discovered issues must be reported and corrective actions taken.
Per 49 CFR 396.13, a driver must conduct a pre-trip inspection at the beginning of each day by reviewing the last DVIR completed on the vehicle and verifying that the required repairs (if any) have been performed.
