Annual Truck Inspection: 12 Months, 14-Month File
Inspection timing and report retention are different. Check the vehicle’s annual inspection evidence and keep the underlying report retrievable.

A 14-month report-retention requirement does not make an annual truck inspection valid for 14 months. For operations subject to the federal periodic-inspection rules, inspection timing, documentation on the vehicle and the retained report are separate checks.
The inspection clock
Under 49 CFR 396.17(c), the required components must have passed inspection at least once in the preceding 12 months, with documentation on the vehicle. The rule includes each vehicle in a combination, so checking a tractor does not settle the documentation question for its trailer.
The retained report
Section 396.21(b) separately requires the original or a copy of the inspection report to be retained for 14 months from the report date. It also addresses availability to officials and the responsibility to obtain the last report when another entity performed the inspection. Keeping a decal and being able to retrieve the underlying report are different tasks.
A practical file check
- Match the vehicle identification on the inspection paperwork to the unit being assigned.
- Identify the inspection date and the applicable next-inspection calculation.
- Check what inspection documentation is on the vehicle.
- Locate the original or copy of the report and identify who can retrieve it.
- When using an outside provider, agree how the completed report will reach the responsible carrier.
Do not treat a retention period as extra operating time
A useful maintenance calendar has separate entries for the inspection deadline and the report-retention period. Combining them into one date invites the wrong question: whether a report is still in the file, rather than whether the unit meets the inspection requirement.
For a leased unit or a trailer obtained from another party, settle the document handoff before a load depends on it. A service invoice saying work was performed is not automatically the inspection report; inspect the document that actually records the inspection.
This is a review of existing federal requirements, not an announcement of a new rule. Qualifying state and other equivalent inspection programs have provisions in section 396.17(f) and section 396.23. Confirm the applicable program and dates with the carrier's compliance lead or qualified inspection provider.

For a business along your route, search Truck Savers Finder and confirm the location, service and appointment directly. A listing does not verify inspection qualifications.
