Ignition Interlock

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 77-90 days. If the device detects any tampering, circumvention, or malfunction, you may be called back into the service center prior to your 77-90 day appointment.

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 time frame. You can reinstate online or visit an MVD or Authorized Third Party office.
