Fleet DVIR & DOT Compliance
If you run commercial vehicles, inspection reports and maintenance records aren't optional — they're federal law. Here's what DVIR requires, how long to keep records, and how to stay audit-ready. Last updated: June 2026 · 8 min read.
This guide is an educational overview, not legal advice. DVIR and DOT rules are set by the FMCSA and can change; verify current requirements at fmcsa.dot.gov and with your state authority.
What a DVIR Is
A Driver Vehicle Inspection Report (DVIR) is the written record a driver completes documenting the condition of a commercial motor vehicle. Required under FMCSA §396.11 and §396.13, it's the paper trail proving that defects affecting safety were found, reported, and fixed before the vehicle went back on the road. At minimum the inspection covers these safety-critical systems:
- Service brakes and trailer brake connections
- Parking (hand) brake
- Steering mechanism
- Lighting devices and reflectors
- Tires, wheels, and rims
- Horn, windshield wipers, and mirrors
- Coupling devices and emergency equipment
The Compliance Cycle
Pre-trip inspection
Before driving, the driver inspects the vehicle and must be satisfied it's in safe operating condition. The driver may not operate a vehicle with a defect likely to cause a breakdown.
Post-trip DVIR
At the end of each driving day, the driver completes a written report covering the required components. Under FMCSA §396.11, a report is required for each vehicle operated.
Repair & certification
If a defect is reported, the carrier must repair it (or determine repair isn't needed) and certify the correction before the vehicle returns to service.
Record retention
DVIRs and certification of repairs must be kept at least 3 months. Annual inspection records are kept 14 months, and maintenance records for the period the vehicle is controlled plus 6 months.
Why It Matters Beyond the Fine
Missing or incomplete records are among the most common violations found in DOT audits, and they hurt your CSA score — which affects insurance rates and the loads you can win. A consistent inspection-and-repair loop also catches small problems before they become roadside breakdowns.
