This application process involves fulfilling certain requirements including installing an ignition interlock device (IID) on your car before your license can be reinstated.

Common Question About IIDs in Arizona


What is an Ignition Interlock Device? 

A certified ignition interlock device is a handheld car breathalyzer. Before an individual can start their car, they must breathe into the device. If alcohol is detected, the car will not start. The International Council on Alcohol, Drugs and Traffic Safety report that “Breath alcohol ignition interlock devices, when embedded in a comprehensive monitoring and service program, lead to 40-95% reductions in the rate of repeat DWI1 offenses of convicted DWI offenders.”

What are the Ignition Interlock Device Laws in Arizona?

As of July 2018, the Arizona Legislature passed a law that requires all ignition interlock devices to be equipped with a digital camera, GPS capabilities, and the ability to transmit ignition data electronically. A number of other restrictions pertaining to cars rented to or driven by persons whose driving privileges are limited can be found in Arizona Revised Statute 28-1464
