How often this comes up
This violation was recorded 64,556 times across the roadside inspections in the FMCSA file, making it the 62nd most frequently cited code.

It sits under 49 CFR Part 383, which covers commercial driver licence. 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.
