will 395.8(a) put my truck out of service?
Unlikely, but possible. Across 17,946 all-time citations for 395.8(a) in our inspection records, only 842 resulted in an out-of-service order — a 4.7% OOS rate. That is dramatically lower than the all-FMCSR average of 31.4%, meaning inspectors usually let you roll after writing the citation. The small but real chance of being parked is higher if the inspector finds you have no records at all versus records that are incomplete, so have whatever documentation you do have ready to present.
