Can I Get a CDL with a DUI?
TL;DR
It depends on how many DUIs and when they occurred. A first DUI typically results in a 1-year CDL disqualification. A second DUI results in a lifetime CDL ban. In some cases, you can still get a CDL after a first DUI once the disqualification period ends — but each state has different rules.
FMCSA Rules: What a DUI Means for Your CDL
Under federal FMCSA regulations, a DUI (or DWI/OWI depending on your state) is considered a 'serious traffic violation' that carries mandatory CDL disqualification:
- First DUI conviction: 1-year CDL disqualification (3 years if carrying hazardous materials)
- Second DUI conviction: Lifetime CDL disqualification (permanent ban from commercial driving)
- DUI in ANY vehicle: Even a DUI in your personal car disqualifies your CDL
- Refusing a BAC test: Treated the same as a DUI conviction for CDL purposes
- BAC threshold for CDL drivers: 0.04% while driving a CMV (vs 0.08% for regular license)
Getting a CDL After a First DUI
After a first DUI, here's your realistic path back to commercial driving:
- Complete your 1-year disqualification period
- Fulfill any state-required DUI programs, probation, or community service
- Reinstate your regular driver's license if it was suspended
- Pass the CDL knowledge tests again (most states require this)
- Complete a new DOT physical and medical card
- Be honest on job applications — many trucking companies do background checks going back 7–10 years
How a DUI Affects Getting Hired With a CDL
Even if you legally qualify for a CDL after a DUI, getting hired by a trucking company is a separate challenge. Many carriers have strict policies:
- Most major carriers (Schneider, Swift, Werner) won't hire drivers with a DUI in the past 3–5 years
- Smaller regional carriers may be more flexible depending on circumstances
- Owner-operator routes may be more accessible, but insurance costs will be higher
- Passenger (P) and School Bus (S) endorsements are extremely difficult to obtain with a DUI history
