Will 392.2IN put my truck out of service?
Almost certainly not. Across 3,021 all-time citations in our inspection records, only 8 resulted in an out-of-service order — a 0.3% OOS rate. For context, the average OOS rate across all FMCSR codes is 31.4%, so 392.2IN sits dramatically below the norm. While this code is OOS-eligible on paper, inspectors almost never pull the trigger. The practical risk at the roadside is low, but the CSA consequence stays with you long after the inspection ends.
