will 172.514(a) put my truck out of service
No, 172.514(a) is not eligible for out-of-service placement on its own. However, our inspection records show that across 48 all-time citations for this violation, 9 vehicles (18.8%) were placed out of service. This indicates inspectors issued the 172.514(a) citation alongside other violations that triggered OOS status. For context, the average FMCSR code results in an OOS placement 31.4% of the time, so 172.514(a) violations are actually placed out of service at a lower rate than typical violations.
