Ignition interlock requirement

| IID on first offense | Required |
| Minimum IID period, first offense | 12 months (may be deferred after 6 months under § 28-3319(H) for a standard first offense); 18 months for a first conviction at 0.20 or more |
| Minimum IID period, repeat offense | 12 months for a second § 28-1381 / § 28-1382(A)(1) conviction within 84 months; 24 months for a second § 28-1382(A)(2) (0.20+) conviction within 84 months or most aggravated DUI (§ 28-1383) convictions |
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 filing required after a DUI | Yes |
|---|---|
| Filing period | 3 years |
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).

Exemptions and special cases
Four questions readers ask once an interlock is ordered — motorcycles, employer vehicles, medical inability to give a breath sample, and reduced-cost programs — answered as Arizona's interlock program page or statute states them.
| Question | Arizona rule |
|---|---|
| Motorcycles | A device may be installed on a motorcycle ADOT MVD's Ignition Interlock FAQ answers 'Can I have an interlock installed on a motorcycle?' by stating that not many companies will install a device on a motorcycle, that those that will often require additional items to ensure security and compliance of the device, and that the person is to contact an interlock provider. The Ignition Interlock Services page says only 'Motorcycles: Contact providers directly for details.' No statute or ADOT page prohibits operating a motorcycle during the requirement or certifies a motorcycle device. What the source says“Not many companies will install an interlock device on a motorcycle. Those that will, often require additional items to ensure security and compliance of the device. Contact an interlock provider for more information.” |
| Employer-owned vehicle | No exemption ADOT MVD's Ignition Interlock Services page states the person may drive only vehicles with a certified device installed, listing 'Work vehicles (including company vehicles you operate)' among them. A.R.S. § 28-1464(G): except in cases of substantial emergency, a person whose privilege is limited or restricted shall not operate a motor vehicle without a functioning certified device during the applicable period. A.R.S. § 28-1461(A)(1)(b) requires proof of installation 'in each motor vehicle operated by the person'. The FAQ adds that a person who owns the company and drives the company truck cannot complete an 'Ignition Interlock Employer Notification form' and must install the device; no such form appears in the MVD forms library (see notes). What the source says“You can only drive vehicles that have a certified ignition interlock device installed. This applies to: All vehicles you own Rental cars Work vehicles (including company vehicles you operate) Any other vehicle you drive for any reason” |
| Unable to provide a breath sample | Not addressed on the official pages read No waiver or alternative device is stated in A.R.S. §§ 28-1461 to 28-1464 or on the ADOT pages. The Ignition Interlock Services page, under 'If You Cannot Blow Into an Ignition Interlock Device', directs a person with a medical condition that prevents providing breath samples to contact an ignition interlock provider for options. What the source says“Contact an ignition interlock provider for options if you have a medical condition that prevents you from providing breath samples.” |
| Reduced-cost / indigent program | Not addressed on the official pages read No reduced-fee or indigent interlock program appears on the ADOT Ignition Interlock Services page, the Ignition Interlock FAQ, the CIID pamphlet (99-0177) or in A.R.S. §§ 28-1461, 28-1462, 28-1464 and 28-1469. A.R.S. § 28-1461(A)(1)(a) requires the person to pay the costs of installation and maintenance; the FAQ states the provider collects a $20 state fee per installed or transferred device and all other fees are set by the provider and service centers and are not regulated by MVD. The ignition interlock device fund (§ 28-1469) is used for administering the article, compliance measures, audits and complaints. |
| Fees: $20 state fee, all other fees set by the provider | FAQ: under A.R.S. § 28-1462 and A.A.C. R17-5-614 the service provider collects $20 for each installed or transferred device; all other fees are established by the provider and service centers and MVD does not regulate or monitor any fee above the $20 install fee. What the source says“the service provider will collect $20 for each installed or transferred device. All other fees are established by the provider and service centers. The MVD does not regulate or monitor any fee above the $20 install fee.” |
| Six Month Deferment | CIID pamphlet 99-0177: some violations may be eligible to remove the device after 6 months if the violation was on or after January 1, 2012, there was no DUI in the last 7 years (84 months), the violation was not an extreme DUI, no accident was involved, at least 16 hours of substance abuse education were completed, there were no violations during the first 6 months and at least 6 months have passed since the reinstatement date; the second 6 months is a probationary period. What the source says“Some violations may be eligible to remove the Interlock device after 6 months. Contact an MVD or Authorized Third Party office if you feel you may be eligible.” |
| Substantial emergency | A.R.S. § 28-1464(G) and (L): the prohibition on operating a vehicle without a functioning device does not apply in cases of substantial emergency, defined as a situation in which a person other than the restricted person is not reasonably available to drive in response to an emergency. What the source says“a person whose driving privilege is limited pursuant to section 28-1381, 28-1382, 28-1383 or 28-3319 or restricted pursuant to section 28-1402 shall not operate a motor vehicle without a functioning certified ignition interlock device during the applicable time period.” |
| Out-of-state residents | ADOT: Arizona interlock requirements must be maintained regardless of where the person lives; a person living in another state contacts an Arizona-authorized provider to locate an authorized service center in that state, which must provide all services required by Arizona law and ensure MVD receives all required electronic reporting. What the source says“If you live in another state and have an Arizona interlock requirement, contact an Arizona-authorized provider to locate an authorized service center in your state. The out-of-state installer must provide all services required by Arizona law and ensure MVD receives all required electronic reporting.” |
| No vehicle or someone else's vehicle | ADOT: a person without a vehicle remains suspended until the provider gives proof of installation; when using someone else's vehicle, some providers require written authorization from all vehicle owners before installation; a person with several vehicles may drive only the ones with devices installed. What the source says“If you don't have a vehicle, your driving privileges remain suspended until your provider provides proof of installation. If you are using someone else's vehicle, some providers require written authorization from all vehicle owners before installation.” |
| Owner who drives the company vehicle | FAQ: a person who owns the company and drives the company truck cannot complete the Ignition Interlock Employer Notification form and must install the device and follow all requirements. What the source says“No, if you are the owner and drive the vehicle, you must install the interlock and follow all requirements.” |
