When Arizona Law mandates use of a CIID following a period of driver license suspension/revocation, you must have one installed by an authorized installer and provide proof of the installation to MVD.

MVD utilizes special forms and procedures to monitor drivers required to have the device installed. MVD issues a replacement driver license containing the words “Ignition Interlock” and marks your record so law enforcement officers will be aware of the CIID requirement if you are stopped.

In cases involving driver license suspension/revocation resulting from a DUI related violation date on or after February 1, 2006, you may be eligible for a restricted driver license (SIIRDL) if you meet the following requirements:

• Complete at least 90 days of the mandated suspension period.
• Contact MVD to verify eligibility.
• No other outstanding withdrawal actions are pending on your driving record.
• Install a Certified Ignition Interlock Device (CIID) on your vehicle and provide proof to MVD with a “Verification of Installation” form.
• Comply with mandatory alcohol treatment programs (if required) and submit proof of completion to MVD.
• Submit proof of future financial responsibility to MVD (e.g., SR22 insurance form).
• Pay all applicable fees

A Special Ignition Interlock Restricted Driver License is valid only during the period of suspension or revocation and allows vehicle operation between the following:

• Place of employment and residence during specified periods of time while at employment.
• Place of residence, the person's place of employment and the person's secondary or postsecondary school according to the person's employment or educational schedule.
• Place of residence and a treatment or screening facility for scheduled appointments.
• Place of residence and the office of the person's probation officer for scheduled appointments.
• Place of residence and the office of a physician or other health care professional.
• Place of residence and a certified ignition interlock device service facility.

A list of ignition interlock service providers authorized for use in the State of Arizona is available online. You may have an MVD-certified ignition interlock device (CIID) installed by contacting an authorized provider. Call the toll-free number of any of the companies listed and ask about the availability of service in your area and associated costs. You are responsible for installation and monitoring fees.

Once installed in your vehicle, the CIID must be calibrated and inspected by a certified installer every 30 days for the first three months and then every other month for the duration of installation requirement. The inspections make sure the device is working properly and detect any issues of non-compliance. Drivers who do not comply with CIID requirements are reported to MVD and may have the period for use extended. In some cases, their driving privilege may be cancelled, suspended or revoked.

In cases involving juveniles who are not statutorily mandated to have a CIID installed but have been ordered by a court to have one, you must maintain the CIID in your vehicle for the duration of the court order. If the device is removed, you will be considered non-compliant and may have your driving privilege cancelled, suspended or revoked.
