How often this comes up

This violation was recorded 12,824 times across the roadside inspections in the FMCSA file, making it the 200th most frequently cited code. Whether a given instance puts a vehicle or driver out of service is decided at the roadside by the inspector, not by the code itself, so the same violation can end a trip or simply be noted.

It sits under 49 CFR Part 390, which covers general requirements. 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.
