Will a 390.17 violation put my truck out of service?
No. FMCSR 390.17 is not an out-of-service eligible violation. Across all 3,805 all-time citations in our inspection records, zero vehicles were placed out of service — a 0.0% OOS rate. For context, the all-FMCSR average OOS rate is 31.4%, so this code sits well below the norm. You will not be parked roadside over this violation alone, but the citation still lands on your inspection report and can affect your carrier's CSA scores, so it should not be ignored.
