Driver Vehicle Inspection Report (DVIR) Explained
A Driver Vehicle Inspection Report (DVIR) is the post-trip written record CDL drivers must complete under 49 CFR §396.11 after each day's work. It documents vehicle condition, any defects found, and whether repairs were made before the next trip.
What Is a DVIR?
A Driver Vehicle Inspection Report (DVIR) is a written report that CDL drivers must complete to document the condition of their commercial motor vehicle (CMV). Federal regulations at 49 CFR §396.11 require drivers to prepare a DVIR at the completion of each day's work on every vehicle they operated. The report covers the vehicle — and any trailer or towed unit — so that defects are caught before they create a safety hazard.
When Must a DVIR Be Completed?
Under 49 CFR §396.11, drivers must complete a DVIR at the end of each day's work on every vehicle they operated. If the driver operated more than one vehicle (e.g., swapped trailers), a separate DVIR is required for each unit. The regulation also requires the driver to review the previous day's DVIR for the same vehicle before operating it (§396.13).
What Must the DVIR Cover?
The DVIR must identify the vehicle by its carrier name, date, vehicle number, and odometer reading. The driver must report any defect or deficiency discovered that could affect safe operation or result in a mechanical breakdown. Parts to inspect include: service brakes (including trailer brake connections), parking brake, steering mechanism, lighting devices and reflectors, tires, horn, windshield wipers, rear-vision mirrors, coupling devices, wheels and rims, and emergency equipment.
What Happens If Defects Are Found?
If the driver notes any defect or deficiency in the DVIR, the carrier must repair the defect before the vehicle is operated again — unless the defect does not affect safe operation and the carrier certifies on the DVIR that repair is not needed before the vehicle is returned to service. A motor carrier representative must certify on the DVIR that the defects were repaired or that repair was not necessary.
How Long Must DVIRs Be Kept?
Under 49 CFR §396.11(c), the original DVIR must be retained by the motor carrier for 3 months from the date the report was prepared. During that period, DVIRs must be available for inspection by FMCSA or state enforcement personnel.
The carrier certification step — what happens after the driver submits
When a driver submits a DVIR with defects noted, the regulation doesn't end there. Under 49 CFR §396.11(b), the next driver to operate that vehicle must be able to see on the DVIR that either the defect was repaired or a carrier representative has certified that the defect does not affect safe operation and that repair is not required before the vehicle returns to service. That carrier certification requires an actual signature — not an assumption that everything got handled. A DVIR with defects noted but no carrier certification showing their disposition is a deficiency flagged in compliance reviews. Make sure whoever handles maintenance sign-off understands they need to complete the certification field, every time.
The driver review requirement before each trip
49 CFR §396.13 requires the driver to review the most recent DVIR before operating a vehicle. The driver must sign the DVIR to acknowledge they reviewed it and that either the defects listed were repaired or they accept the carrier's certification that repair is not necessary. A driver who skips this review and operates without signing the prior DVIR has created a compliance gap in the paper trail — one that surfaces quickly during a roadside inspection or compliance review if someone asks to see documentation of the pre-trip review process.
Frequently Asked Questions
Is a DVIR required even if the driver found no defects?
Yes. If the driver found no defects, the DVIR must state that fact. A blank or missing form is not compliant under 49 CFR §396.11.
Does a short-haul driver still need to complete a DVIR?
Most short-haul drivers are still subject to DVIR requirements. The short-haul exemption (§395.1(e)) covers hours-of-service log books — not vehicle inspection reports. Check your specific operation against 49 CFR Part 396 for exemptions.
Can a DVIR be electronic?
FMCSA allows electronic DVIRs as long as the electronic record meets the retention and signature requirements of 49 CFR Part 396. Carriers should verify their electronic system satisfies those standards.
What if a defect is found mid-trip, not during the post-trip inspection?
Drivers must report any discovered defect as soon as practicable. If a defect that affects safe operation is found while driving, the driver should stop and notify the carrier. The defect gets documented on the DVIR at the end of the day's work. For safety-critical issues discovered while the vehicle is moving — brake failure, tire blowout — follow roadside emergency procedures first; documentation follows.
