Will 397.13(a) put my truck out of service?
No. Across our 13 million inspection records, zero out of 12 all-time citations for 397.13(a) resulted in an out-of-service order — a 0.0% OOS rate. This is substantially lower than the 31.4% average OOS rate across all FMCSR codes. You will receive a citation and CSA points, but your truck will not be placed out of service on the spot. Your focus should be immediate compliance and addressing the violation in writing to your carrier.
