Commercial DUI

How a DUI affects CDL holders and professional drivers.

Commercial DUI (CDL drivers)

Commercial drivers face lower BAC thresholds and strict disqualification rules. A DUI in a personal vehicle can still impact CDL status.

  • Lower per se BAC (often 0.04)
  • Lengthy disqualification periods
  • No hardship license for commercial operation in many states
  • Collateral employment consequences
