What Is the Annual DOT Vehicle Inspection?
Every commercial motor vehicle operated in interstate commerce must pass a periodic (annual) DOT inspection at least once every 12 months, performed by a qualified inspector, with the report kept on file (49 CFR 396.17).
Which vehicles need the annual DOT inspection?
Commercial motor vehicles operated in interstate commerce. For a chauffeured fleet running larger passenger vehicles across state lines, that's an annual requirement on top of any state or city inspection.
Who can perform it, and what records do you keep?
A qualified inspector who meets the federal training and experience requirements performs it. Keep the inspection report (or a copy) on file — the documentation is exactly what a DOT audit asks to see.
How is it different from a state safety inspection?
The federal annual inspection is separate from and in addition to state or city inspections. An interstate operator can owe both — for example, the Illinois Certificate of Safety every six months and the federal annual DOT inspection on top.
