FMCSR 392.2W: Ill or Fatigued Driving — Driver Q&A

Almost certainly not — but there is a small risk. Across 64,257 all-time citations for 392.2W in our inspection records, only 59 vehicles were placed out of service, producing a 0.1% OOS rate. For context, the all-FMCSR average OOS rate is 31.4%, making 392.2W one of the least likely codes to ground your truck on the spot. That said, "almost never" is not "never" — if an officer believes your condition makes continued operation immediately dangerous, that 0.1% scenario becomes real. Don't argue impairment at the roadside; comply and address the underlying condition.

392.2W carries a severity weight of 8 — one of the highest possible scores in the CSA Unsafe Driving BASIC. Points are then multiplied based on how recently the violation occurred: inspections within the last 6 months carry a 3× time-weight multiplier, dropping to 2× for 7–12 months and 1× beyond that. At 8 severity weight × 3 time multiplier, a fresh 392.2W citation can register as 24 weighted points on your PSP record. Because this sits in the Unsafe Driving BASIC — the most scrutinized category by shippers and insurers — the impact on carrier SMS scores is disproportionately high relative to its 0.1% OOS rate.

Act on three fronts immediately. First, document your condition: note your hours-of-service logs, any medical records, or evidence that contradicts the officer's observation — this is your DataQs foundation if you contest later. Second, review the full inspection report carefully, because our inspection data shows 392.2W frequently appears alongside other citations: in the last 90 days, 1,019 shared inspections also included a 393.9 lamp violation, 751 included 392.2RG, and 553 included a 393.78 windshield defect. Address every co-cited violation before your next dispatch. Third, notify your fleet safety manager the same day — delayed reporting compounds CSA BASIC damage.

It's serious on CSA points but moderate on OOS risk relative to its peer codes. Our inspection records show 392.2W's 0.1% OOS rate matches 392.2RG (0.1% across 96,652 citations) and 392.2-SLLSR (0.1% across 191,232 citations). However, peer code 392.2-SLLEQP carries a 2.4% OOS rate across 72,352 citations — 24× higher — so 392.2W is toward the lower end of OOS danger within this family. The bigger concern is volume rank: 392.2W is #44 out of 3,036 FMCSR codes by citation count, meaning enforcement attention on this code is intense and inspectors are well-practiced at issuing it.

Yes, you can submit a DataQs Request for Data Review (RDR), and it's worth doing if the facts support you. 392.2W is a judgment-based finding — the officer observed behavior and concluded you were impaired by fatigue or illness. That subjectivity cuts both ways: it's harder to prove than a broken lamp, but it also means a well-documented rebuttal (clean hours-of-service logs, medical records showing no illness, dash-cam footage showing normal operation) can succeed. Submit your RDR through the FMCSA DataQs portal, attach every piece of supporting documentation, and direct your challenge to the issuing state agency. Approval removes the violation from your PSP and CSA records entirely.

Texas dominates enforcement of this code by a wide margin. In the last 180 days, our inspection records show TX issued 18,174 citations for 392.2W — with 15 of those resulting in an OOS action (0.1% rate). Illinois was a distant second at 185 citations (1 OOS, 0.5% rate), and North Carolina recorded 30 citations with zero OOS placements. The Texas volume is not a statistical quirk — it reflects both the state's overall commercial vehicle inspection activity and the concentration of cross-border traffic where fatigued driving is more likely to be flagged. If you operate Texas corridors regularly, this code should be a standing agenda item in driver safety briefings.

Urgency is high, and the trend line confirms it. Our inspection records show 392.2W citations climbed steadily over the last year: from 3,401 in May 2025 to a 12-month peak of 4,006 in October 2025, with February 2026 reaching 4,043 citations. The last 90 days alone account for 8,943 citations, and the full last-12-month total is 40,495 — meaning roughly 63% of the code's entire 64,257 all-time citation history was issued in just the past year. That acceleration signals active enforcement prioritization. A violation sitting uncontested on your PSP today will carry its full 3× time multiplier for the next six months.

Both the driver and the carrier are affected. Under FMCSA's CSA methodology, roadside violations are attributed to the carrier's SMS BASIC scores — in this case the Unsafe Driving BASIC — and simultaneously recorded on the individual driver's Pre-Employment Screening Program (PSP) report. The carrier's SMS score influences intervention likelihood and is visible to shippers and insurers. The driver's PSP record follows them to every future employer who pulls it. A single 392.2W at severity weight 8 is significant enough that neither side can treat it as a paperwork nuisance — the carrier's safety rating and the driver's employability are both on the line.
