FMCSR 392.22(b) Warning Device Placement: Driver Q&A

No — almost certainly not. Across all 5,635 all-time citations for 392.22(b) in our inspection records, only 1 vehicle was ever placed out of service, producing an OOS rate of effectively 0.0%. For comparison, the average OOS rate across all FMCSR codes nationally is 31.4%. This violation is not OOS-eligible under the standard criteria, so inspectors cannot legally pull you from the road for this citation alone. You will receive the citation and be allowed to continue your trip, but the violation still enters your inspection record and feeds into CSA scoring.

The citation adds CSA points based on its assigned severity weight within the Unsafe Driving BASIC. The specific severity weight for 392.22(b) is not included in the data available here, so a precise point count cannot be stated. What is known: the violation falls under the Unsafe Driving BASIC, and citations carry a time-based multiplier — violations within the last 6 months count most heavily, those in the 6–12 month window count at a reduced rate, and anything older than 12 months ages off entirely. Check your SMS BASIC score in the FMCSA portal to see the current impact on your record.

Act immediately on documentation and carrier notification — this one is administrative, not equipment. Here is a concrete checklist:

1. Get a copy of the inspection report before leaving the scale or roadside location.
2. Review the specific finding — was it failure to place devices at all, or improper placement distance or position?
3. Notify your safety department the same day; the citation attaches to both your record and the carrier's USDOT number.
4. Photograph your triangle/flare setup on future breakdowns to document compliance.
5. Check your company's warning device procedure — our records show large carriers like New Prime Inc (50 citations) and J B Hunt Transport Inc (27 citations) have accumulated significant counts, suggesting procedural drift is a fleet-wide risk.
6. Consider a DataQs challenge if the inspection narrative is factually incorrect.

It is moderate in frequency but low in severity compared to its peer group. At 5,635 all-time citations, 392.22(b) ranks #321 out of 3,036 FMCSR codes by citation volume — placing it in the top 11% by frequency. However, its 0.0% OOS rate is far below the all-FMCSR average of 31.4%. Peer codes in the same Unsafe Driving category carry far higher volumes: 392.2 (operating while ill or fatigued) has accumulated 1,208,164 citations. The practical takeaway is that inspectors cite this code regularly enough to take it seriously in training programs, but it rarely results in immediate operational impact.

Yes, you can submit a DataQs Request for Data Review (RDR) if the facts on the inspection report are wrong. Because 392.22(b) is a documentation and procedure-based finding — not an equipment defect — the most viable grounds for a challenge are: (1) the inspector recorded the violation in error and warning devices were properly placed, (2) the inspection narrative contains factual inaccuracies about placement distance or location, or (3) the citation was applied to the wrong vehicle or driver. Submit your RDR through the FMCSA DataQs portal with the inspection report number, your supporting documentation, and any photographs. If upheld, the citation is removed from both your PSP record and the carrier's SMS data.

The statistics block for 392.22(b) does not include a state-by-state breakdown, so specific states cannot be identified from the available data. What the data does show is that citations are spread across a nationwide enforcement pattern — 5,635 all-time citations with no citations recorded in the last 12 months, suggesting enforcement peaked in an earlier period. Fleet managers should check state-level inspection activity through the FMCSA's SMS portal for the most current geographic distribution. High-volume trucking corridors and states with active commercial vehicle enforcement units historically account for a disproportionate share of all Unsafe Driving citations.

Address it immediately, even though the urgency is procedural rather than equipment-based. The 0.0% OOS rate means this citation won't park your truck, but the 12-month citation trend tells an important story: our records show 0 citations in the last 12 months and 0 in the last 90 days, down from 5,635 all-time. That drop suggests enforcement patterns have shifted, but the violation remains in the code set and inspectors can resume citing it at any time. More importantly, every citation in the Unsafe Driving BASIC has a time-decay multiplier — citations issued today count at full weight for the next 6 months. Fix your deployment procedure now to avoid compounding your BASIC score.

It follows both — simultaneously. Under FMCSA's CSA methodology, a roadside violation is linked to the driver's Pre-Employment Screening Program (PSP) record and to the carrier's USDOT number for SMS BASIC scoring. The violation appears in the carrier's Unsafe Driving BASIC, which is why our records show large fleets like New Prime Inc (50 citations), J B Hunt Transport Inc (27 citations), and Swift Transportation Co of Arizona LLC (21 citations) carrying notable citation counts — every driver citation accumulates against the carrier. Drivers who change employers carry their PSP history with them; carriers carry their SMS history regardless of driver turnover. Both parties have independent incentives to resolve and prevent this violation.
