No. Across all 1,668 citations for 392.2-SLTFC in our database, zero trucks were placed out of service—a 0.0% OOS rate. This is substantially lower than the 31.4% national average across all FMCSR codes. A 392.2-SLTFC citation will not trigger an immediate roadside shutdown, though it will appear on your inspection record and count toward CSA severity points.
A 392.2-SLTFC citation carries a CSA severity weight of 8 points. In the FMCSA's Safety Management Evaluation System (SMS), this feeds into the Unsafe Driving BASIC category as a single violation. The total CSA impact also depends on the frequency and timing of violations within a rolling 12-month window; repeated citations accelerate your BASIC percentile and can trigger interventions.
First steps: (1) Document the citation details and time of inspection. (2) Review co-occurring defects noted on the same inspection—our data shows that 392.2-SLTFC often occurs alongside tire pressure issues (22 shared inspections), cab/body part damage (20 each), and fuel system leaks (20). (3) Address any equipment defects listed alongside the fatigue finding. (4) If you believe the citation is inaccurate, file a DataQs RDR (Request for Data Revisions) within 90 days through your carrier's FMCSA CSA profile.
It ranks #574 out of 3,036 FMCSR codes by citation frequency—moderately common. Among peer codes in the same category, 392.2-SLTFC has a 0.0% OOS rate, matching most variants (392.2-SLL, 392.2-SLLTCD, 392.2-SLLS2), but notably lower than 392.2-SLLEQP at 2.4% OOS. The core 392.2 code averages 1,208,164 citations with 0.8% OOS. Your variant is enforced but rarely results in shutdown.
Yes. The FMCSA DataQs system allows drivers and carriers to submit RDRs (Requests for Data Revisions) for 392.2-SLTFC citations. Since this is a behavioral finding—fatigue or illness—contestation works best if you have evidence the inspector's judgment was incorrect or if documentation (e.g., medical records, dispatch logs, rest breaks) supports your ability to safely operate at that time. Submit within 90 days of the inspection date through your carrier's FMCSA profile.
Over the last 180 days, our records show 392.2-SLTFC is most frequently cited in Michigan (75 citations), Washington (60), and New York (58). Other high-enforcement states include Georgia (51), Pennsylvania (50), and California (35). Enforcement density varies; inspect local patterns if you operate in these regions, as higher citation volume may indicate more aggressive fatigue-assessment practices.
Moderate urgency. Because 0.0% of 392.2-SLTFC citations result in OOS status, there is no immediate equipment or out-of-service deadline. However, the citation does add CSA points and is logged to your record. In the last 90 days, we recorded 258 citations for this code—reflecting steady enforcement. Focus on documented rest compliance, HOS adherence, and any co-occurring mechanical defects noted in the inspection to prevent repeat citations.
Freightliner units account for 336 of the 1,668 all-time 392.2-SLTFC citations, followed by FRHT (211), Volvo (124), Kenworth (106), and Peterbilt (104). This distribution roughly mirrors overall fleet composition; these brands are among the most common heavy-duty tractors in operation. Vehicle make itself does not cause fatigue citations—driver behavior does—but these numbers reflect where enforcement volume is highest.
