Will a 392.2-SLLL citation put my truck out of service?
No, not automatically. Across our 13 million inspection records, 392.2-SLLL carries a 9.1% out-of-service rate—meaning 91 of every 100 drivers cited for this code stay in service. That rate is significantly lower than the 31.4% average across all FMCSR codes. The violation is cited for operating while fatigued or ill, but the inspection officer uses judgment. If you're safe to continue after being observed, you'll likely stay on the road.
