A CMV driver is convicted of a moving traffic violation (not a parking violation) while driving their personal vehicle. Within how many days must the driver notify their employer?

49 CFR 383.31(a) (notification of convictions); AAMVA CDL Manual Sec. 1.4, p.1-10

This rule applies even off the job, in a driver's own car. Missing the 30-day window is itself a compliance failure separate from the underlying violation, and employers rely on this self-reporting to track driver qualification under FMCSA rules.
