Driver vehicle inspection reports are one of the simplest safety tools in trucking. They are also one of the most misunderstood. Drivers often do not know when a written report is required, and carriers often miss their own duties once a defect is reported.
Two Different Rules: Pre-Trip and Post-Trip
The DVIR process is built on two separate sections of Part 396.
- Post-trip report (49 CFR 396.11). At the end of each day’s work, the driver prepares a written report on each vehicle operated that day.
- Pre-trip review (49 CFR 396.13). Before driving, the driver must be satisfied the vehicle is in safe operating condition, review the last DVIR, and sign it if defects were noted.
People often call the whole process “pre-trip and post-trip inspections.” The regulation focuses the written report on the end of the day, and the pre-trip duty on checking the vehicle and the prior report.
What the Post-Trip Report Must Cover
Under 49 CFR 396.11, the post-trip report must cover at least these parts and accessories:
- 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
- Emergency equipment
The report must identify the vehicle and list any defect or deficiency the driver discovered or that was reported to them that would affect safe operation or result in a breakdown. The driver signs the report. If a driver operates more than one vehicle in a day, a report is needed for each one.
When a Written Report Is Not Required
For property-carrying vehicles, drivers are not required to prepare a written post-trip report when no defect or deficiency is discovered or reported. The driver still inspects the vehicle. They just do not need paperwork for a clean inspection.
This relief does not apply to passenger-carrying vehicles. Passenger carrier drivers must still complete a written DVIR every day, even when there are no defects.
There is also a separate exception for driveaway-towaway operations, and intermodal equipment has its own reporting rules. If your operation falls into one of those categories, check the specific provisions.
Many property carriers still require a written report every day as company policy. That is allowed and can make it easier to show that inspections actually happened.
The Carrier’s Duties After a Defect Is Reported
Once a driver reports a defect, the responsibility shifts to the carrier. Under 49 CFR 396.11, before the vehicle is driven again the carrier must:
- Repair any listed defect that would likely affect safe operation.
- Certify on the original report that the defect has been repaired, or that repair is unnecessary.
- Keep the original DVIR, the certification of repairs, and the certification of the driver’s review for three months from the date the report was prepared.
The next driver then completes the loop under 49 CFR 396.13 by reviewing the report and signing to acknowledge that repairs were made or were not needed. This is where the pre-trip and post-trip rules connect.
Auditors often look for that full chain on sampled reports: the driver’s report, the carrier’s repair certification, and the next driver’s signature. Missing any link is a problem.
Common Mistakes and a Simple Workflow
These errors come up frequently in audits and at roadside:
- Passenger carriers skipping written reports on defect-free days
- Defects listed with no repair certification
- Repairs certified but the next driver never signed
- Reports discarded before three months
- Drivers “pencil whipping” inspections without looking at the vehicle
- Electronic DVIR systems that do not capture all required signatures
Roadside inspectors notice when a truck has obvious defects that never show up on a DVIR. That pattern suggests inspections are not really happening. A clean process looks like this:
- Drivers perform a real pre-trip inspection and review the last report before driving
- Drivers note all defects on the post-trip report, even minor ones
- Maintenance staff review every report with defects before the next dispatch
- Repairs are made and certified on the report
- The next driver signs the report acknowledging the repair
- Reports are filed and kept for at least three months
Electronic DVIR apps are acceptable if they capture the required information and signatures. Make sure yours does.
DOT Compliance Watch helps you keep DVIRs and repair records organized with each vehicle’s maintenance file, so you can find them when an auditor asks. Pair it with regular driver coaching and your DVIR process will hold up. For specific questions, check with FMCSA or visit our resources page.
Close the loop every time
A DVIR only protects you if the defect gets fixed and documented. DOT Compliance Watch keeps inspection and repair records organized by unit so nothing falls through the cracks. Start a 14-day free trial today.
