will 172.316(a) put my truck out of service
No. Across our inspection records, 172.316(a) has never resulted in an out-of-service placement—the OOS rate is 0.0%. This is significantly lower than the national average OOS rate of 31.4% across all FMCSR codes. While the violation will be cited, it does not carry the immediate vehicle removal that accompanies many hazardous materials violations. However, the citation will still appear on your CSA record and should be addressed promptly to avoid accumulation.
