Will 385.111(a) put my truck out of service?
Yes—but this is extremely rare. Across our 13 million+ inspection records, every single citation for 385.111(a) resulted in an out-of-service placement (100% OOS rate). However, the violation itself is cited very infrequently: only 25 times all-time in our database, with zero citations in the last 12 months. For context, the national average OOS rate across all FMCSR codes is 31.4%, so 385.111(a) is far more likely to trigger an OOS than typical violations.
