Commercial Vehicle Annual DOT Inspection Prep Checklist [FREE PDF]

The Federal Motor Carrier Safety Administration (FMCSA) requires all commercial motor vehicles to undergo a periodic inspection at least once every 12 months per 49 CFR 396.17. Vehicles that fail to meet inspection standards may be placed out of service, resulting in costly downtime and CSA score penalties. This preparation checklist helps fleet mechanics and DOT compliance officers systematically verify all major inspection components before the official annual inspection occurs.

  • Are all tires properly inflated per manufacturer specification and free of observable under-inflation?
  • Are all lug nuts present, properly torqued, and free of damage?

Coupling Devices & Trailer Connection

Verify all coupling components are in proper working order to prevent trailer separation during operation.

  • Is the fifth wheel plate free of cracks and properly mounted to the frame?
  • Does the fifth wheel locking mechanism engage and release correctly without binding?
  • Are safety chains or cables present, properly attached, and of adequate strength rating?
  • Are glad hand seals on air supply and control lines in good condition and leak-free?

  • Are all required documents (registration, operating authority, IFTA decals, permits) present in the cab?
  • Is the horn operational and in proper working condition?

Inspection Summary & Certification

Document overall vehicle readiness, outstanding defects, and certify the inspection preparation is complete.

  • Are any items identified during this prep inspection that would constitute a CVSA out-of-service defect?
  • Have all identified defects been documented on a work order and scheduled for repair before the annual inspection?
  • Is the vehicle's current annual inspection sticker still valid, or has it expired?
