Confirm the device, provider and written quote

Check the responsible authority’s current approval information for the particular device and installer. Request the billing unit, included services, actual paid visit schedule, taxes, fees and removal terms in writing. Confirm financial assistance separately.

Add your own quoted charges in the IID worksheet. Unknown charges stay unknown; no local price or appointment count is assumed.

Restricted License with IID

Available

Arizona allows a restricted driving permit with IID for DUI offenders, permitting travel to work, school, and court-ordered treatment. The IID must be installed on every vehicle the offender operates.

Tampering / Circumvention Penalties

Tampering with an IID in Arizona is a Class 1 misdemeanor. Penalties include up to 6 months in jail, fines up to $2,500, and extension of the IID requirement. Driving a vehicle without an IID while required is a separate offense.

Early Removal

Arizona does not allow early removal of IID. The full 12-month (or longer) period must be completed with clean compliance.

Arizona-Specific Notes

Arizona is one of the strictest DUI states in the nation. Even a first-offense regular DUI requires 12 months of IID. Extreme DUI (BAC 0.15%+) and super extreme DUI (BAC 0.20%+) carry additional penalties but the same IID duration. Arizona also has mandatory minimum jail time for all DUI offenses.
