What the rule says
Every truck, tractor and trailer must pass a periodic inspection at least once every 12 months, with proof of it on the vehicle (49 CFR 396.17).
When it puts you out of service
Not out of service in this data, but it is one of the most cited paperwork codes on small carriers, and it is fixed only by having the inspection done and the proof aboard.
The codes on the inspection report
| Code | What the officer wrote | Severity weight | Citations, 5 to 50 trucks | Out of service |
|---|---|---|---|---|
| 396.17C-PI | “Operating a CMV without documentation of a periodic inspection” | 4 | 25,985 | 0.0% |
| 396.17C | “Operating a CMV without proof of a periodic inspection” | 4 | 10,264 | 0.1% |
How it scores (violation points)
How it scores: in FMCSA's Safety Measurement System each violation counts its severity weight, plus 2 if it put the driver or vehicle out of service, times 3 in its first 6 months, 2 from 6 to 12 months, and 1 from 12 to 24 months. FMCSA has approved a simpler scale that is not live yet.
How to fix it
- Have a qualified inspector (49 CFR 396.19) complete the annual inspection on the unit that was cited.
- Carry the report, or a sticker or decal that shows it, on the vehicle (396.17(c)).
- Keep the inspection report for 14 months (49 CFR 396.21(b)), and check every other unit's date the same day.
Stop it happening again
- Track each unit's annual due date, trailers included, and book it 30 days ahead.
Challenging it in DataQs
Use DataQs (dataqs.fmcsa.dot.gov) only when the report is wrong: the wrong carrier or vehicle, a violation that did not happen, or a citation a court dismissed without a fine or found you not guilty of, which removes it from the Safety Measurement System; a conviction of a different charge lowers its weight to 1 (FMCSA adjudicated citations policy). Fixing the defect afterward is not a reason to remove it; keep the repair record instead.
FileFlo tracks every unit's annual inspection date with the driver files and sends the reminder before it lapses.
Run it yourself: the Audit-Ready Setup, $499 through December 31, 2026, then $199 a month for up to 15 trucks. Or FileFlo runs it: $1,500 a month for up to 15 trucks, Setup included, and your first month back if you are not happy.
About these numbers
Counts are violations cited in roadside inspections used in FMCSA's Safety Measurement System from September 25, 2024 to September 24, 2026 (dataset 8mt8-2mdr on data.transportation.gov, October 2026 run). Carriers with 5 to 50 trucks means 66,936 active interstate for-hire carriers with 5 to 50 power units and more trucks than buses, based in the 50 states or DC, from FMCSA's census file. This is FileFlo's reading of public FMCSA data, not an FMCSA rating. Severity weights are the current SMS weights.
