392.2-SLLOWZ Citation: Will My Truck Go Out of Service?

No. A 392.2-SLLOWZ citation will not result in an out-of-service order. Across our inspection records, this violation has a 0.0% out-of-service rate—none of the 474 all-time citations resulted in immediate removal from service.

However, this differs sharply from the national average. The all-FMCSR average out-of-service rate is 31.4%, so this particular violation is treated as a citation-level offense rather than a safety-critical removal.

392.2-SLLOWZ carries a CSA severity weight of 8. In the CSA system, this weight is multiplied by a 30-day decay factor—meaning points accumulate most heavily in your first 30 days post-citation, then gradually reduce over the next 30 days.

The exact point total depends on your carrier's current profile and FMCSA's real-time CSA calculation, but severity 8 is moderate-to-serious. Compare this to lower-severity equipment violations (weight 1–3) and higher-severity HOS or crash violations (weight 10).

Immediate actions:

1. Document your state of health — If you were genuinely ill or fatigued due to a specific medical condition or emergency, collect supporting evidence now.
2. Request inspection reports — Get the full roadside inspection documentation from the officer or your state DOT.
3. Check for linked violations — Our data shows 392.2-SLLOWZ often co-occurs with HOS violations (395.24 and 395.22H4-ELDBRODS in the last 90 days). Review your ELD and log records immediately.
4. Notify your carrier — Alert dispatch and safety management. Do not delay.
5. Consult DataQs if applicable — If the citation is factually incorrect (e.g., officer made an error about your condition), file a DataQs Request for Reconsideration within 90 days.

Not as severe as many others. While 392.2-SLLOWZ has a 0.0% out-of-service rate, other variants of the 392.2 code show higher risk: 392.2-SLLEQP carries a 2.4% OOS rate, and the general 392.2 code itself has a 0.8% rate.

Compared to the all-FMCSR average of 31.4% OOS, this citation is on the lighter end. That said, fatigue/illness violations are safety-critical concerns and can damage your CSA score and carrier safety record. Repeated citations compound the problem.

Yes, you may be able to contest it through DataQs (the FMCSA's Request for Reconsideration process). Eligibility depends on the nature of the finding:

• Contestable: Officer made a factual error (e.g., misidentified your vehicle, misread your condition, or the inspection violated procedure).
• Not contestable: Your actual physical or mental state genuinely impaired your ability to drive safely, and the officer observed objective signs (erratic steering, inability to focus, slurred speech, etc.).

File within 90 days with supporting evidence (medical records, witness statements, logbook corrections).

Our inspection records from the last 180 days show 392.2-SLLOWZ citations concentrated in three states:

1. Missouri — 63 citations
2. Arizona — 31 citations
3. Pennsylvania — 28 citations

These three account for the vast majority of citations. If you operate in these corridors, be especially alert to fatigue management and medical fitness checks before starting a shift.

The trend is uneven month-to-month, but overall steady. In the last 12 months, we recorded 283 citations for this violation. The highest single month was February 2026 with 37 citations; the lowest were April and August 2025 with 10 citations each.

In the last 90 days, 77 citations were issued. This does not suggest a sharp rise in enforcement, but enforcement remains consistent. Fatigue and illness violations are perennial enforcement priorities for roadside inspectors.

Across our all-time data, Federal Express Corporation (USDOT 86876) leads with 7 citations, followed by J B Hunt Transport Inc (USDOT 80806) with 5, and New Prime Inc (USDOT 3706) with 4.

This pattern likely reflects citation volume relative to fleet size and hours-of-service exposure rather than a safety deficiency unique to these carriers. Smaller fleets and owner-operators may be underrepresented in absolute counts simply due to fewer inspections overall.
