FMCSA commercial driver disqualification offenses and periods

Every offense that triggers mandatory disqualification of a commercial driver's license (CDL) holder under 49 CFR 383.51, with the disqualification period for each combination of offense, vehicle type (CMV, non-CMV, hazmat), and occurrence count (first, second, third). Covers four federal tables: major offenses (DUI, leaving scene, felony — 1 year to lifetime), serious traffic violations (speeding 15+ mph, reckless driving, improper lane change — 60 to 120 days), railroad-highway grade crossing violations (60 days to 1 year), and violating out-of-service orders (180 days to 5 years). Answers 'my driver got a DUI in their personal car — is their CDL at risk?' with the exact period and the regulatory citation.
