Commercial Driver's License DUI

For people who drive professionally a commercial driver’s license is essential for their employment.  What happens when you get arrested for DUI?  And what can you do about it?

DUI While Operating a Commercial Vehicle

Arizona drivers operating a vehicle with a commercial driver’s license (or CDL) have different standards than other drivers. This is because of the safety issues associated with operating larger vehicles such as trucks, tractor-trailers, and buses.  According, the law treats Arizona DUI cases differently when the person has a CDL.

Arizona DUI laws are a lot more restrictive for people with commercial driver’s licenses (CDL). For example, most Arizona drivers will be in violation of the law if their blood alcohol concentration is .08 or greater; commercial drivers have a much tougher standard. For drivers with a CDL, the legal limit is a blood alcohol concentration of .04 or greater. More information can be found in section 28-1381(A)(4) of the Arizona Revised Statutes:

  • It is unlawful for a person to drive or be in actual physical control of a vehicle in this state under any of the following circumstances:
  • If the vehicle is a commercial motor vehicle that requires a person to obtain a commercial driver license as defined in section 28-3001 and the person has an alcohol concentration of 0.04 or more.

A commercial driver may also face a disqualification of their license, which may put the commercial driver’s livelihood at risk.
