Quick Answer
A DVIR (Driver Vehicle Inspection Report) is a federally required record showing that a commercial driver inspected the vehicle's safety-critical parts before and after operating it. Required under 49 CFR §396.11, it covers items like brakes, tires, lights, and coupling equipment. Carriers must keep DVIRs for at least three months, and any uncertified defect can pull the vehicle out of service.
Key Takeaways
- A DVIR documents a pre-trip and post-trip safety inspection of the CMV.
- It's required under FMCSA regulation §396.11 and must be retained for 3 months.
- If no defects are found, property carriers generally don't have to file a report — but must still inspect.
- Defects must be certified as repaired before the vehicle returns to service.
What does a DVIR cover?
A DVIR records the condition of the vehicle's safety-critical components. At minimum, inspections look at:
- Brakes (service and parking)
- Tires and wheels
- Lights and reflectors
- Steering and suspension
- Coupling devices (for combination vehicles)
- Mirrors, horn, windshield wipers
- Emergency equipment
If the driver finds a defect that affects safe operation, it must be reported and repaired — and the repair certified — before the truck runs again.
Is a DVIR required every day?
Yes for post-trip: drivers must inspect and, if defects exist, complete a report at the end of each driving day. Since 2014, property-carrying drivers who find no defects aren't required to submit a written report — but the inspection itself is still expected, and the no-defect rescission doesn't apply to passenger carriers.
Who is exempt from DVIR requirements?
Section §396.11 lists exceptions. DVIR rules generally don't apply to:
- Private motor carriers of passengers (non-business)
- Driveaway-towaway operations
- Motor carriers operating only a single commercial motor vehicle
Most fleets and many owner-operators still fall under the requirement.
How long must you keep DVIRs?
Carriers must retain DVIR records for at least three months at their principal place of business. Skipping this is a common audit finding.
Why DVIRs matter for your CSA score
A failed inspection can park a truck and cost real money in downtime — one industry estimate puts an out-of-service truck near $861 per event, before fines or repairs. Uncertified defects and missing DVIRs also feed the Vehicle Maintenance category of your CSA score, which brokers and insurers watch closely.
Paper vs. electronic DVIRs
Electronic DVIRs (eDVIRs) speed up the whole process — the driver completes the inspection in an app, defects route straight to a mechanic, repairs get certified, and everything is time-stamped and stored automatically. For fleets already running an ELD, adding eDVIR keeps inspection and HOS records in one system.

FAQ
Q: What's the difference between a pre-trip and post-trip DVIR?
A: A pre-trip inspection happens before driving to catch problems early; the post-trip inspection at the end of the day is what the §396.11 report requirement is built around. Both protect you at a roadside inspection.
Q: Do owner-operators need to do DVIRs?
A: If you operate more than one CMV you're covered; single-vehicle operators may fall under the exception — but doing the inspection anyway protects your CSA score and catches problems before they become violations.
Q: Can a DVIR be done on my phone?
A: Yes — electronic DVIRs done in a compliant app satisfy the requirement and are faster to store and retrieve than paper.
