DOT Vehicle Maintenance Records: What Every File Needs

Every truck you control should have a file that tells its whole story. Auditors open it to see whether you run a real maintenance program.

5 min read · Updated 2026-08-05

What belongs in each vehicle file

  • Vehicle identification — make, year, VIN, and your company unit number, plus tire size
  • Annual inspection — a current periodic inspection on file for the unit
  • Inspection, repair, and maintenance history — a record of the work done and the dates
  • DVIRs — connecting driver-reported defects to the repairs that fixed them

A systematic program

The point is not just storing receipts — it is showing you inspect, repair, and maintain vehicles on a schedule. Recurring roadside defects in the same system are a signal that a program is missing.

How long to keep it

Maintenance history is generally kept while the vehicle is under your control and for a period after it leaves the fleet; the annual inspection documentation is kept for roughly 14 months. See the full retention cheat sheet.

Tie it together: vehicle files, DVIRs, and annual inspections are one story. When they connect cleanly, the vehicle section of an audit goes fast.
