DOT annual inspection: the checklist behind 49 CFR 396.17

The requirement in one paragraph

Under 49 CFR 396.17, every commercial motor vehicle must pass a periodic inspection at least once every 12 months. The inspection must cover, at minimum, the components listed in Appendix A to Part 396 — the federal minimum periodic inspection standards. Documentation of the inspection must be retained, and proof of the inspection must be kept on the vehicle.

Who is allowed to perform it

Rule 396.19 sets qualification requirements for inspectors. The person performing the annual inspection must be qualified through training or experience — for example, having completed a relevant training program or apprenticeship, and being able to identify defective components. Rule 396.25 sets separate qualification requirements for brake inspectors.

The carrier is responsible for keeping evidence of the inspector's qualifications for as long as they perform inspections, plus one year afterward.

What Appendix A covers

• Brake system: service brakes, parking brake, brake drums and rotors, hoses and tubing, low-pressure warning, air compressor, air loss rate
• Coupling devices: fifth wheel, pintle hooks, safety devices, saddle mounts
• Exhaust system: leaks, mounting, discharge location
• Fuel system: leaks, secure mounting, fuel cap
• Lighting devices: all required lamps operative
• Safe loading: securement of cargo and protection against shifting
• Steering mechanism: steering wheel free play, column, gear box, linkage, power steering
• Suspension: springs, u-bolts, torque rods, axle positioning parts, air suspension components
• Frame: members, cross members, tire and wheel clearance, adjustable coupler assembly
• Tires: tread depth, condition, load restrictions on steering axle
• Wheels and rims: cracks, unseated locking rings, fasteners, welds
• Windshield glazing and wipers
• Rear impact guards and rear-end protection where required

Records and proof on the vehicle

The inspection report identifies the inspector and the vehicle, lists the components inspected, and states whether the vehicle passed. Carriers must keep the original or a copy where the vehicle is housed or maintained for 14 months from the report date.

Proof of the current inspection must also be on the vehicle — commonly a decal or a copy of the report in the cab. A missing proof of inspection is a roadside finding even when the inspection itself was performed.

How it interacts with other inspections

• The driver's daily vehicle inspection report (DVIR) is a separate, daily obligation under 49 CFR 396.11.
• California carriers in the BIT program owe 90-day periodic inspections in addition to the federal annual inspection.
• A roadside CVSA inspection is enforcement, not a substitute for your periodic inspection program — though a passed CVSA Level I inspection can satisfy the annual inspection requirement when properly documented.

Making the annual survivable

The fleets that never scramble are the ones that treat the annual as the audit of a program they already run. Track the due date per unit, inspect defects when they appear rather than at the annual, and keep repair evidence attached to the vehicle.

AssetStacc tracks annual due dates per unit alongside 90-day vehicle inspection intervals and preventive maintenance, and keeps every inspection PDF, photo and repair permanently on the asset.
