Arizona Ignition Interlock and SR-22 Guide
Installation, restricted-license credit, insurance filings, and removal after an Arizona DUI.
When is an interlock required?
An alcohol DUI conviction commonly triggers mandatory interlock. A qualifying drug-only conviction generally does not automatically do so. Some drivers voluntarily elect an interlock-restricted license during an administrative suspension or qualify for one after a refusal. A court order or separate MVD action may also require interlock.
What order should I follow?
- Check the MVD compliance report and confirm whether the device is mandatory or part of an optional restricted-license pathway.
- Ask MVD about the installation deadline, earliest credit date, and whether an existing SIIRDL installation counts.
- If SR-22 is required, contact the insurer for the correct Arizona filing and verify MVD received it.
- Use an MVD-authorized interlock provider; confirm installation reporting and required monitoring.
- Complete screening and any other prerequisites; pay applicable fees when MVD indicates they are due.
- Obtain the proper reinstated or restricted driving status before driving.
- Before removing the device, get MVD confirmation that all interlock obligations and credit requirements are satisfied.
Can SIIRDL time count toward a later conviction?
Under applicable Arizona rules, qualifying time under an issued SIIRDL may count toward a later mandatory interlock period. That is not the same as simply having a device installed voluntarily. Eligibility, dates, age, and statutory exceptions matter. Keep the device in place and obtain an individualized MVD credit calculation before removal.
Who needs an SR-22?
An SR-22 is evidence of future financial responsibility filed by an insurer. It is generally associated with certain conviction and refusal actions, but is not ordinarily required solely because of a standalone 90-day APS suspension. Another outstanding action may still require it. Ask MVD for the precise requirement and duration before purchasing or cancelling coverage.
Frequently asked questions
My suspension period ended. Can I drive?
Not automatically. Complete all outstanding MVD requirements and verify that your driving privilege is valid before driving.
What if my license is from another state?
Arizona can restrict your privilege to drive in Arizona. Your home state may impose additional requirements; contact that licensing agency directly.
Can I remove my interlock when the 90-day APS suspension ends?
Not without checking. A pending or subsequent conviction may impose a separate mandatory interlock period, and eligible SIIRDL time may count toward it.
Does buying an SR-22 automatically reinstate my license?
No. SR-22 is only one possible compliance requirement. Screening, fees, suspension/revocation dates, and interlock may also apply.
