Ranks #834 of 3,146 FMCSR codes by citation frequency • OOS rate of 0.0% is below the FMCSR-wide average of 33.2%.
Operating a commercial motor vehicle while the driver's ability or alertness is so impaired through fatigue, illness, or any other cause as to make it unsafe for the driver to begin or continue to operate the vehicle.
Direct answers grounded in TruckCodex inspection data
No. Across our inspection records, 392.2-SLLT has never resulted in an out-of-service placement—the OOS rate is 0.0%. All 670 all-time citations for this code resulted in the truck remaining in service. This is significantly lower than the national average OOS rate of 31.4% across all FMCSR codes, making this one of the least likely violations to trigger immediate removal from operation.
This violation carries a CSA severity weight of 8 points. The actual impact on your CSA score depends on the 30-day window—if you receive multiple citations within 30 days, the weight is applied only once per violation type. A single 392.2-SLLT citation counts as 8 points. Fleet managers should note that this is a moderate severity violation; it will affect your HOS BASIC and overall safety rating but is not in the highest-risk category.
First, understand why the officer cited you—fatigue, illness, or impaired alertness. Next, check for related violations on your inspection report. Our data shows 392.2-SLLT frequently co-occurs with medical certificate violations (391.41APC, cited together in 7 recent inspections) and seat belt violations (392.16-D, 5 co-occurrences). If medical issues are involved, verify your medical certificate is current and valid. Document any extenuating circumstances for your DataQs appeal if you disagree with the citation.
Moderately serious, but less enforcement-heavy than broader 392.2 codes. The 392.2 parent category has 1,208,164 total citations with a 0.8% OOS rate, while 392.2-SLLT represents only 670 citations nationally—ranking #828 of 3,036 FMCSR codes by volume. Most peer codes in the ill/fatigued category show similar low OOS rates (0.0%–2.4%), so while it affects your CSA score, it's unlikely to remove you from the road immediately.
Yes, you can file a DataQs request to challenge the citation if you believe it was incorrectly cited or documented. DataQs allows drivers and carriers to dispute violations recorded in the FMCSA database. Your appeal should focus on whether the officer had legitimate evidence of impaired alertness, fatigue, or illness at the time of inspection. Success depends on documentation—if you have records showing you were fit to operate, include them. The FMCSA reviews all DataQs requests and may remove the citation if evidence supports your challenge.
Minnesota leads by a wide margin with 53 citations in the last 180 days, followed by Ohio with 18 citations and Arkansas with 14 citations. These three states account for the bulk of 392.2-SLLT enforcement. If you operate in Minnesota, be especially aware of inspectors' focus on driver alertness and fatigue indicators. The remaining top states (Tennessee, Georgia, Maryland, Washington, Idaho, Arizona, Pennsylvania) each show single-digit citation counts, indicating enforcement is concentrated in the upper midwest and mid-atlantic regions.
Not urgent from an out-of-service standpoint, but urgent for your CSA score and safety record. Because the OOS rate is 0.0%, you won't be forced off the road. However, our 90-day data shows 68 citations for this code, indicating steady enforcement activity. The real urgency is preventative: address whatever caused the citation—get adequate rest, manage health issues, and ensure your medical certificate is valid. For fleet managers, July 2025 saw a spike of 57 citations, so monitor seasonal fatigue patterns and strengthen HOS compliance programs.
Both. FMCSA CSA violations follow the driver but roll up into the carrier's safety profile. A 392.2-SLLT citation on your record adds 8 CSA points to your HOS BASIC and Safety Management BASIC, which also affects your company's overall safety rating. If you're an owner-operator, it's your responsibility alone. If you drive for a carrier, your violation contributes to their CSA score, which can impact insurance rates, customer audits, and regulatory attention. Fleet managers should implement fatigue management training and monitor driver medical certificate validity to prevent these citations company-wide.
