DVIR regulations and the importance of vehicle inspection reports

Driver Vehicle Inspection Reports (DVIR) are federally mandated records under FMCSA regulations, specifically 49 CFR §396.11 and §396.13, used to document the mechanical condition of commercial motor vehicles. These reports are designed to identify defects in components such as brakes, steering, tires, and lighting before they pose safety hazards.

A complete DVIR process involves three distinct legal certifications. First, the driver signs to report the findings of a pre-trip or post-trip inspection. Second, if defects are identified, a mechanic or authorized carrier representative must sign to certify that the repairs were completed or deemed unnecessary before the vehicle returns to service. Third, a driver must sign to certify they have reviewed the previous report and confirmed the vehicle is safe to operate.

Failure to maintain these records or skipping the third signature—confirming the review of previous inspections—can have legal implications. In the event of a collision, these documents serve as critical evidence to determine if a carrier was aware of mechanical issues prior to dispatching a vehicle.
