Interlock Manufacturers and Installers
A certified ignition interlock device is a breath alcohol-testing instrument connected to the ignition and power system of the vehicle.
An MVD-authorized company must install the interlock. Check the website or call the toll-free number for any company listed below for the availability of service in your area and associated costs.
Please Note: Your Arizona Driving Privileges must be reinstated in order to establish a starting point for your required ignition interlock timeframe. To reinstate, please visit an MVD or Authorized Third Party office.
