Arizona ignition interlock & DUI requirements

What Arizona law requires

Arizona's ignition interlock, SR-22, and reinstatement rules are set by the statute and agency rules cited below. The values in the tables on this page are taken from those sources and are not interpretations of how they apply to any particular case.

Primary source: A.R.S. § 28-3319

Ignition interlock requirement

Mandatory for every alcohol-related first conviction. Under A.R.S. § 28-1381(I)(6), a person convicted of a first DUI that involved intoxicating liquor 'shall be required by the department, on report of the conviction, to equip any motor vehicle the person operates with a certified ignition interlock device pursuant to section 28-3319'; § 28-3319(D)(1)(a) sets the period at twelve months. The requirement does not apply to drug-only DUI convictions, for which the court 'may' order a device (§ 28-1381(P)). Under § 28-3319(H), MVD defers the remainder of the 12-month period after six months for a first (§ 28-1381(I)) offender who completes a 16-hour alcohol education program, maintains the device, and meets the other listed conditions. Extreme DUI (0.15–0.20, § 28-1382(A)(1)) also carries 12 months; super-extreme DUI (0.20 or more, § 28-1382(A)(2)) carries 18 months.

SR-22 requirement

An SR-22 is a certificate an insurer files with the state to confirm that a driver carries the liability coverage the state requires. Some states use an FR-44 or a different form for alcohol-related offenses; where Arizona does, the sources below say so.

SR-22 (ADOT MVD calls it 'Future Financial Responsibility'). A.R.S. § 28-3319(A) bars MVD from ending a DUI suspension/revocation or issuing a special ignition interlock restricted license until the person provides proof of financial responsibility. The MVD SR-22 page states the filing is required for 3 years from the end date of a court-conviction DUI suspension, an implied-consent suspension, or an alcohol/drug-related revocation, and throughout the restricted-license period for a SIIRDL (not required for a SIIRDL issued due to an Admin Per Se suspension).

Frequently asked questions

Is an ignition interlock required after a first DUI in Arizona?

Yes, for alcohol-related convictions. Under A.R.S. § 28-1381(I)(6), a person convicted of a first DUI involving intoxicating liquor is required by MVD, on report of the conviction, to equip any vehicle the person operates with a certified ignition interlock device under § 28-3319, which sets the period at twelve months. For a DUI that does not involve alcohol, the court may (but need not) order a device (§ 28-1381(P)).

How long does the Arizona interlock requirement last?

A.R.S. § 28-3319(D) sets 12 months for a standard or extreme DUI (§ 28-1381, § 28-1382(A)(1)) or a second offense within 84 months, 18 months for a 0.20-or-higher conviction (§ 28-1382(A)(2)), and 24 months for a repeat 0.20+ conviction or most aggravated DUI convictions. Under § 28-3319(H), MVD defers the remainder after six months for a first offender who completes a 16-hour alcohol education program and the other listed conditions.

Does Arizona require an SR-22 after a DUI?

Yes. A.R.S. § 28-3319(A) provides that MVD shall not terminate a DUI suspension or revocation, or issue a special ignition interlock restricted driver license, until the person provides proof of financial responsibility. ADOT MVD's Future Financial Responsibility (SR-22) page states the filing must be maintained for 3 years from the end date of a court-conviction DUI suspension, implied-consent suspension, or alcohol/drug-related revocation.

What does Arizona charge to reinstate a license after a DUI?

ADOT MVD's DUI page lists the reinstatement fees after a DUI conviction as a $10 suspension fee and a $50 fee for an Admin Per Se suspension, and notes an additional application fee may be required. Under A.R.S. § 28-1461(A), the driver also pays the costs of installing and maintaining the interlock device; MVD's interlock page states providers collect a $20 state fee per installed or transferred device.

Who may install an ignition interlock in Arizona?

Under A.R.S. § 28-1462, the MVD assistant director certifies ignition interlock devices and publishes a list of certified devices and manufacturers. ADOT MVD's Ignition Interlock Services page states that an MVD-authorized company must install the interlock and lists the current authorized providers and device models; devices must include a camera and GPS.
