Will 375.505(c) put my truck out of service?
No. Across our inspection records, 375.505(c) citations have never resulted in an out-of-service order—the OOS rate is 0.0% on all 59 citations in our database. This code is not OOS-eligible under FMCSA rules, meaning even if cited, your truck and license remain operable. Compare this to the all-FMCSR average OOS rate of 31.4%, and you can see this violation carries lower immediate enforcement severity.
