Interlock Installation and Monitoring
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.
Once installed in your vehicle, the interlock device must be calibrated and inspected by a certified installer every 30 days for the first three months, then as designated by your certified interlock installer as required.
Drivers who do not comply with interlock requirements are reported to MVD and may have the period of time for use extended. In some cases, their driving privilege may be canceled, suspended or revoked.
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.
