A rough record doesn’t automatically end a trucking career — but some things disqualify you, sometimes for a year, sometimes for life, and the rules for CDL holders are stricter than for regular drivers. Here’s how a DUI, a felony, or a spotty record actually affects getting and keeping a CDL, and how drivers get back on the road.
CDL holders are held to a 0.04 BAC — half the 0.08 limit for regular drivers — and a DUI in any vehicle, including your personal car off duty, can disqualify your CDL. The commercial standard follows you everywhere, not just in the truck.
FMCSA major violations — DUI/DWI, refusing a test, leaving the scene, using a vehicle to commit a felony, driving a CMV on a revoked CDL, or negligent homicide with a vehicle — carry a 1-year disqualification for a first offense (3 years if you were hauling HazMat), and a lifetime disqualification for a second. That’s federal, on top of any state penalty.
Serious violations — 15+ over the limit, reckless driving, following too close, improper lane changes, texting or handheld use while driving — stack up: two within 3 years means a 60-day disqualification, and three within 3 years means 120 days. The small stuff adds up fast.
A felony generally doesn’t bar you from holding a CDL (the exception is using a CMV to commit a felony). But it can block the HazMat endorsement — the TSA background check disqualifies certain felonies — and, more practically, carriers set their own hiring standards. Many won’t hire recent felonies; some are second-chance friendly. Getting the license and getting hired are two different bars.
HazMat requires a TSA security threat assessment. Certain felonies — terrorism, explosives, and some violent or drug crimes — are permanently or temporarily disqualifying for HazMat specifically. You can still drive non-HazMat freight.
After a drug or alcohol violation, you go through the Substance Abuse Professional (SAP) return-to-duty process — evaluation, education or treatment, and follow-up testing — and clear the FMCSA Drug & Alcohol Clearinghouse before you’re eligible again. Time, a clean record, and completing the SAP process are how drivers come back.
One old mistake usually isn’t the end — check your state DMV and the FMCSA rules for your specific offense, be upfront with carriers, and target second-chance-friendly companies. But a DUI as a CDL holder is serious, and a second major offense is a lifetime ban. This is general information, not legal advice; rules vary by state and offense, so confirm with your DMV/FMCSA and, for your situation, an attorney.
