Will 383.71(h) put my truck out of service?
Almost certainly not. Across all 4,444 all-time citations for 383.71(h) in our inspection records, only 22 vehicles were placed out of service — an OOS rate of just 0.5%. The regulation is also flagged as not OOS-eligible as a standard matter, which is consistent with that extremely low rate. Compare that to the all-FMCSR average OOS rate of 31.4%, and it's clear this citation rarely stops a truck at the roadside. The 22 OOS placements that did occur likely involved compounding factors from other violations cited at the same inspection.
