The Annual Vehicle Inspection
Once every twelve months, on every unit in the combination, with the proof carried on the vehicle. Missing records for a majority of your fleet fails a safety audit automatically.
What the rule requires
Under 49 CFR § 396.17, every commercial motor vehicle must be inspected at least once every 12 months, covering the parts and accessories listed in Appendix A to Part 396.
Each unit counts separately. In a combination, the tractor, the semitrailer, any full trailer and any converter dolly each need their own inspection. Carriers who think of "the truck" as one thing end up with an inspected tractor pulling an uninspected trailer.
Who can perform it
You do not have to take it to a dealer. The inspection may be done by:
- The motor carrier itself, or the intermodal equipment provider, and
- Qualified third parties — the regulation names a commercial garage, fleet leasing company, truck stop or similar commercial business — provided they have appropriate facilities and employ qualified inspectors.
The word doing the work is qualified. The inspector must meet the qualification requirements in the regulations, and you should hold evidence of that qualification. An owner-operator who is qualified may inspect their own vehicle; being the owner does not disqualify you, and being untrained does.
The documentation, and where it lives
The rule is specific: documentation of the inspection must be on the vehicle. That can be either:
- The inspection report itself, or
- A sticker or decal showing the inspection date, the name and address of the inspecting entity, information identifying the vehicle, and a certification that it passed.
A report filed neatly in your office and nowhere near the truck does not satisfy this. Keep the copy in the cab and the original in your records.
State inspections usually count. A state or Canadian inspection that meets the minimum standards satisfies the federal requirement for 12 months from the last day of the inspection month. If your state already inspects commercial vehicles, you may not need a separate federal annual inspection — check that yours qualifies before paying for both.
Why this one is worth taking seriously
Missing annual inspection records for 51 percent or more of your vehicles is one of the sixteen conditions that fail a new entrant safety audit outright. For a one-truck carrier, 51 percent means one truck.
It also feeds the Vehicle Maintenance BASIC, which is publicly visible to brokers. See CSA scores.
The routine that works
- Diary it eleven months out, not twelve. Shops get booked.
- One folder per unit, including trailers.
- Copy in the cab, original in the file.
- Keep the inspector's qualification evidence if you or an employee performs it.
The annual inspection is separate from the daily checks. Those are covered in driver vehicle inspection reports.
