Arizona State Laws and Requirements

Arizona Ignition Interlock Devices

Arizona interprets driving under the influence (DUI) as driving with a blood alcohol content (BAC) of .08 percent or higher. A standard DUI is considered as driving a vehicle with a BAC of .08 percent, or .04 percent for drivers of commercial offenders. The legal limit for those under 21 is 0 percent.

State Interlock Regulations

Arizona requires all DUI offenders to install an ignition interlock device in order to regain their driving privileges, and license reinstatement is used to establish the time frame for the IID requirement.

As part of the IID program, offenders are charged a $20 fee for installation, and drivers are monitored by the MVD.
