DEFINITION
The DOT annual inspection is the periodic inspection required by FMCSA 49 CFR 396.17. Every commercial motor vehicle must pass a comprehensive inspection at least once every 12 months, performed and documented by a qualified inspector against the minimum standards in Appendix A to Part 396.
ALSO KNOWN AS · FMCSA periodic inspection · annual DOT inspection · 49 CFR 396.17 · Appendix A inspection
FMCSA 49 CFR 396.17 requires that every commercial motor vehicle — including each component of a combination such as a trailer or converter dolly — be inspected at least once every twelve months. The inspection must cover, at minimum, all the components listed in Appendix A to Part 396: brake system, coupling devices, exhaust system, fuel system, lighting, safe loading, steering, suspension, frame, tires, wheels and rims, windshield glazing, and wipers.
Crucially, the person performing the inspection must be a qualified inspector under 49 CFR 396.19 — meaning they have the knowledge and training to identify defects and have passed an FMCSA-recognized program, or hold equivalent training and experience. The inspector's qualification must be documented and retained by the carrier; this is a separate requirement from the brake-inspector qualification in 396.25.
Proof of the annual inspection travels with the vehicle. The carrier must keep a copy of the inspection report, and the vehicle must display a periodic-inspection decal or carry the report. A vehicle that passes a roadside inspection under a CVSA program can have that inspection accepted in lieu of the annual periodic inspection, which is why many fleets time the annual around a clean roadside or self-inspection.
The DOT annual is the heaviest of the FMCSA inspection cadences — distinct from the daily pre-trip (396.13) and end-of-day DVIR (396.11). Where the daily checks are about catching defects that emerge in service, the annual is a deep, component-level verification that the whole vehicle still meets the minimum Appendix A standards.

Only a qualified inspector under 49 CFR 396.19 — someone with documented training or experience to identify the defects listed in Appendix A and who has completed an FMCSA-recognized program or equivalent. The carrier must retain evidence of that qualification.
At least once every 12 months for every commercial motor vehicle, including each unit of a combination (tractor, trailer, and dolly are each inspected). A passing CVSA roadside inspection can be accepted in place of the annual.
RELATED · TERMS
A DVIR is the written record a commercial driver completes documenting the condition of a vehicle. Under FMCSA 49 CFR 396.11, a driver must prepare a report at the end of each driving day on every vehicle operated, noting any defect that would affect safe operation.
A pre-trip inspection is the safety check a commercial driver performs before operating a vehicle. Under FMCSA 49 CFR 396.13, the driver must be satisfied the vehicle is in safe operating condition, review the last DVIR, and confirm any noted defects were repaired before driving.
An OSHA qualified person is one who, by possession of a recognized degree, certificate, or professional standing, or by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter, work, or project.
