Quick checklist

  • List every unit in service during the audit period.
  • Confirm each unit has a profile record.
  • Check annual inspection status.
  • Match repair invoices to unit numbers.
  • Close the loop on roadside inspection defects.

Why this matters

The fastest way to find maintenance gaps is to review records by unit, not by invoice date. A truck without a complete unit file is easy to miss when receipts are mixed together.

What to prepare

Area Records to gather
Gap checks
  • Missing unit profile
  • Missing annual inspection
  • No preventive maintenance record
  • Repair invoice without unit number
  • Open defect or roadside repair proof missing
Follow-up actions
  • Request corrected invoice
  • Save inspection form
  • Document repair completion
  • Update unit roster
  • Schedule overdue inspection

Common gaps

  • Trailers are left out of the unit list.
  • Vendor invoices use plate numbers while internal files use unit numbers.
  • Annual inspection proof is in the truck only.
  • Repairs are paid but not linked to a defect report.

Before / During / After audit

Before

  • Print the unit list and mark each file complete or incomplete.
  • Call shops for corrected invoices.
  • Resolve annual inspection gaps first.

During

  • Provide records by unit and date.
  • Keep corrected or follow-up documents with the original record.

After

  • Require unit numbers on every shop invoice.
  • Review open maintenance items weekly.
  • Archive sold-unit records.
