will 386.83(c) put my truck out of service
No. Across our 13 million inspection records, 386.83(c) has never resulted in an out-of-service order—the OOS rate is 0.0%. All 3 all-time citations for this code left trucks in service. This is well below the national average OOS rate of 31.4% across all FMCSR codes, making it a relatively low-enforcement violation that does not trigger immediate removal from operation.
