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.

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.
