How often this comes up

This violation was recorded 33,600 times across the roadside inspections in the FMCSA file, making it the 98th most frequently cited code.

It sits under 49 CFR Part 393, which covers parts and accessories. To see it in context, look up a carrier and read its inspection history: the same code appearing repeatedly is a different signal from a single occurrence.
