will 172.516(d) put my truck out of service?
No. Across our 13 million inspection records, 172.516(d) has a 0.0% out-of-service rate—meaning every citation on record resulted in the truck remaining in-service. This is significantly below the 31.4% all-FMCSR average. The violation is documented and cited, but does not trigger an immediate roadside out-of-service order.
