will 177.800(c) put my truck out of service
No. Across our 13 million inspection records, the 0.0% out-of-service rate for this violation shows that 177.800(c) citations do not result in immediate vehicle removal. All 6 all-time citations in our database were issued without an out-of-service order. However, this is significantly below the 31.4% all-FMCSR average OOS rate, making it one of the least likely violations to trigger an immediate roadside pull. That said, the citation itself carries weight in your CSA profile.
