Annual inspections, DVIRs and maintenance records
Updated September 3, 2026 · 7 min read
Vehicle records are the second thing an auditor asks for after driver files, and they trip carriers up in a different way: the inspections usually happened, but the paperwork proving it was never kept, or was kept for the wrong length of time. Three separate records are involved, with three different retention periods.
The annual inspection
Under 49 CFR 396.17, every commercial motor vehicle must pass a periodic inspection at least once every 12 months. The standards it must meet are set out in Appendix A to Part 396.
The inspection must be performed by a qualified inspector who meets the requirements of 396.19 — meaning documented training or experience. Your mechanic may well be qualified, but you need to be able to show why they are, and the inspector's qualification records are themselves something an auditor can ask for.
The report must be retained for 14 months from the inspection date, kept where the vehicle is housed or maintained. Fourteen, not twelve — the extra two months exist so the previous report is still on hand when the next one is due.
The decal is optional; the report is not
A carrier may put an inspection decal on the vehicle instead of carrying a copy of the report in the cab. That is a convenience about what rides in the truck. It does not replace the requirement to retain the report itself on file.
Carriers who rely on the sticker and never file the paperwork discover this during an audit, when a decal on a bumper is not the record being asked for.
When a DVIR is actually required
This is widely misunderstood. For property-carrying carriers, a driver vehicle inspection report is required at the end of the driving day only when a defect or deficiency is found. Reports showing no defects are not required and do not need to be retained.
Passenger-carrying operations are different: a DVIR is required at the end of each driving day regardless of whether anything was found.
Where a defect is reported, the chain matters more than the form. The carrier must certify the defect was repaired, or that repair was unnecessary, before the vehicle is dispatched again. A DVIR noting a problem with nothing following it is worse than no DVIR at all, because it documents that you knew.
DVIRs and the associated certification of repair are retained for three months.
Maintenance records
Separately from inspections, 396.3 requires a systematic maintenance record for each vehicle under your control: identifying information for the unit, and a history of inspection, repair and maintenance.
These are retained for one year, and for six months after the vehicle leaves your control — so selling or returning a leased unit does not immediately clear the obligation.
Roadside inspection levels, briefly
Roadside inspections are graded by level and are a separate matter from your annual inspection. A Level I is the full North American Standard inspection covering both driver and vehicle. Level II is a walk-around covering the same ground without going under the vehicle. Level III is driver-only — credentials, medical card, hours of service. Levels IV through VIII cover special examinations, hazmat, and electronic inspections.
A clean Level I can satisfy the annual inspection requirement if it meets the Appendix A standards and you retain the report, which is worth knowing before paying for an inspection you already had.
Common questions
What are the DOT annual vehicle inspection requirements?
Under 49 CFR 396.17, every commercial motor vehicle must pass a periodic inspection at least once every 12 months, meeting the standards in Appendix A to Part 396, performed by an inspector qualified under 396.19.
How long do you have to keep an annual inspection report?
Fourteen months from the inspection date, retained where the vehicle is housed or maintained.
Is a DVIR required every day?
For property-carrying carriers, only when the driver finds a defect or deficiency. No-defect DVIRs are not required. Passenger-carrying operations must complete a DVIR at the end of every driving day regardless.
How long do you keep DVIRs?
Three months, along with the certification that any reported defect was repaired or that repair was unnecessary.
What are the DOT inspection levels?
Level I is the full North American Standard inspection of driver and vehicle. Level II is a walk-around without going underneath. Level III is driver credentials only. Levels IV through VIII cover special, hazmat and electronic inspections.
Can a roadside inspection count as my annual inspection?
A Level I inspection can satisfy the periodic inspection requirement if it covers the Appendix A standards and you retain the report as your inspection record.
Who can perform a DOT annual inspection?
An inspector meeting the qualification requirements of 49 CFR 396.19 — documented training or experience. You must be able to produce evidence of your inspector's qualifications, not just the inspection report.
