FMCSR 396.17C: No Proof of Periodic Inspection — Driver FAQ

Almost certainly not. Across 74,506 all-time citations in our inspection records, 396.17C has resulted in an out-of-service order only 43 times — an OOS rate of just 0.1%. For context, the average OOS rate across all FMCSR codes is 31.4%. This violation is a paperwork deficiency: the inspector found no proof of a current periodic inspection on the vehicle. Unless there is a separate equipment-based violation on the same inspection, you will almost always be cited and sent on your way rather than parked.

396.17C carries a CSA severity weight of 3. That base score gets multiplied depending on how recently the violation occurred: inspections within the last 6 months apply a 3× time-weight multiplier, dropping to 2× for 7–12 months and 1× after that. So a fresh citation adds an effective 9 weighted points to your Vehicle Maintenance BASIC before any other adjustments. Because this code is ranked #31 out of 3,036 FMCSR codes by citation volume, inspectors write it frequently, meaning repeat citations can stack quickly in your CSA window.

Get your paperwork in order before your next dispatch. Here's the immediate checklist:

1. Locate the annual inspection report. It must be on the vehicle or obtainable from your carrier within the inspection window.
2. Check your carrier's maintenance files — the report should already exist if the inspection was completed.
3. Audit co-occurring violations. Our records show that in the last 90 days, 396.17C appeared on the same inspections as 393.9 (inoperable required lamp, 2,266 shared inspections), 393.95A (fire extinguisher missing, 1,163 shared inspections), and 393.78 (defective windshield, 1,236 shared inspections). Walk around the truck and fix any lamp, extinguisher, or glass issues before the next roadside stop.

It is high-volume but low-severity compared to peer codes. 396.17C sits at a 0.1% OOS rate, far below the 31.4% all-FMCSR average. Compare that to peer Vehicle Maintenance code 396.3(a)(1) — general inspection/repair/maintenance — which carries a 45.3% OOS rate across 236,919 citations, or 393.9(a) (inoperable required lamps) at a 15.4% OOS rate across 660,737 citations. 396.17C will not park your truck, but its severity weight of 3 and its position as the 31st most-cited code nationally mean it contributes meaningfully to your CSA score if it recurs.

Yes, and documentation violations like this one are among the more contestable findings. Because 396.17C is purely a paperwork issue — the inspector did not see proof of a periodic inspection at the time of the stop — you can submit a DataQ challenge through FMCSA's DataQs system if you can produce evidence that a valid annual inspection report existed and was on the vehicle (or should have been). A copy of the dated inspection report, a maintenance log entry, or a carrier affidavit can support your Request for Data Review (RDR). If the challenge succeeds, the citation is removed from your SMS record and no longer counts against your BASIC score.

Texas is by far the most active enforcement state for this violation. In the last 180 days alone, our inspection records show Texas issued 15,110 citations for 396.17C — more than seven times the next closest state. Iowa came in second at 1,952 citations, followed by North Carolina at 1,803 citations. Illinois (865) and New Mexico (329) round out the top five. If you regularly run lanes through Texas or the Southeast, keeping your annual inspection report in the cab is especially critical.

Enforcement is consistently high and shows no sign of slowing. Our records show 44,434 citations in just the last 12 months and 8,995 in the last 90 days alone. Monthly volumes have been steady, ranging from roughly 3,600 to 4,246 citations per month from May 2025 through March 2026. Because the OOS rate is only 0.1%, officers use this citation as a low-friction write-up during any inspection stop. A missing annual inspection report is one of the easiest violations for an inspector to record — and one of the easiest for a fleet to prevent by simply keeping the document in the cab.

It follows both, but in different BASIC categories. In FMCSA's CSA Safety Measurement System, a 396.17C violation is assigned to the Vehicle Maintenance BASIC for the carrier, where it affects the carrier's percentile ranking against peers. For the driver, it also appears on their individual SMS record under the same BASIC. Large carriers in our records — including Swift Transportation (85 citations) and Federal Express Corporation (70 citations) — accumulate these violations across their fleets, showing how repeated individual citations roll up into a carrier-level compliance problem. Keeping proof of inspection on the vehicle protects both the driver's record and the fleet's CSA standing.
