FMCSR 392.22(a): Emergency Warning Devices Not Displayed — FAQ

No. Across all 5,302 citations of 392.22(a) in our inspection records, not a single one resulted in an out-of-service order — that is a 0.0% OOS rate. For context, the all-FMCSR average OOS rate is 31.4%, so this code sits well below the typical enforcement threshold. You will be cited and the violation goes on your record, but you will not be parked on the side of the road as a direct result of this specific finding.

4 points is the severity weight assigned to 392.22(a). That base score is then multiplied by a time-weight factor under the CSA SMS model — violations in the most recent 6 months carry the highest multiplier (generally 3×), violations 7–12 months old carry a lower multiplier (2×), and violations 13–24 months old carry no multiplier (1×). So a fresh 392.22(a) citation effectively contributes 12 weighted points to your Vehicle Maintenance BASIC until it ages past six months. After 24 months, it drops off entirely.

Take these steps immediately:

1. Audit your emergency kit today. The citation means an inspector found your warning devices (triangles, flares, or fusees) either missing or not properly displayed. Verify you have the full required set onboard and know how to deploy them.
2. Document what you fixed. Photograph your warning devices in place. Keep the receipt if you had to purchase replacements.
3. Notify your safety department. Carriers like NEW PRIME INC and SWIFT TRANSPORTATION CO OF ARIZONA LLC — both appearing in our top-cited carrier list — have internal safety review processes triggered by any citation.
4. Check for related violations. Our records show 392.22(a) often appears alongside other roadside findings, so review the full inspection report for companion violations that may need separate attention.

It is relatively low-severity by OOS standards, but not trivial. The 0.0% OOS rate for 392.22(a) contrasts sharply with peer codes in the same Vehicle Maintenance category — for example, 396.3(a)(1) carries a 45.3% OOS rate across 236,919 citations, and 393.9(a) has a 15.4% OOS rate across 660,737 citations. The all-FMCSR average OOS rate is 31.4%. So while 392.22(a) won't park your truck, the 4-point CSA severity weight is real, and with 5,302 all-time citations it ranks #328 out of 3,036 FMCSR codes by enforcement volume — meaning inspectors actively write it.

Yes, you can file a DataQ challenge, and this type of citation is often contestable. Because 392.22(a) is a display or equipment-presence violation — not a complex mechanical judgment call — a successful challenge typically requires documented evidence: a photograph showing warning devices were present and properly deployed at the time of the stop, a witness statement, or a dash-cam clip. Submit your challenge through the FMCSA DataQs portal (the Request for Data Review, or RDR, process). The reviewing state agency or FMCSA must respond. If the finding is removed, it is deleted from your CSA profile; if it is corrected to a lesser violation, your point exposure drops accordingly.

Our inspection records do not break down 392.22(a) citations by state in the current data snapshot, so we cannot name specific states ranked by count for this code without risking inaccuracy. What the data does show is that the violation has accumulated 5,302 all-time citations nationally, with heavy-volume carriers operating coast-to-coast — including NEW PRIME INC (53 citations), SWIFT TRANSPORTATION CO OF ARIZONA LLC (23 citations), and J B HUNT TRANSPORT INC (23 citations) — all appearing at the top of the enforcement list, suggesting exposure across major interstate corridors rather than concentration in a single region.

Fix it immediately, even though enforcement has been quiet recently. Our inspection records show 0 citations for 392.22(a) in the last 90 days and 0 in the last 12 months. However, the all-time total is 5,302 citations, proving inspectors have historically written this violation at a meaningful rate — it ranks #328 out of 3,036 FMCSR codes. The 0.0% OOS rate means the urgency is not about being parked today; it is about accumulating 4 CSA severity points per incident that drag your Vehicle Maintenance BASIC score upward over time and can affect carrier safety ratings.

It hits both. Under FMCSA's CSA system, a 392.22(a) citation is recorded against the carrier's USDOT number and also tied to the driver's PSP (Pre-Employment Screening Program) record. Carriers see it in their Vehicle Maintenance BASIC score; future employers pulling your PSP report will see it as well. The 4-point severity weight applies on both sides. This is why both the driver and the fleet safety manager have an independent interest in contesting incorrect citations and in maintaining proper warning device compliance before the truck ever stops on a roadway.
