Will a 385.301(a) citation put my truck out of service?
No. Across our 13 million inspection records, 385.301(a) has never resulted in an out-of-service placement. Our data shows a 0.0% OOS rate for this code, meaning all 30 all-time citations issued resulted in warnings or fines but no vehicle removal from service. This is significantly more lenient than the 31.4% average OOS rate across all FMCSR codes, making 385.301(a) among the least severe violations an inspector can cite.
