Minimum Coverage Requirements in Arizona
Arizona operates under a tort-based liability system and requires all drivers to carry proof of financial responsibility. The Arizona Motor Vehicle Division (MVD) enforces these requirements and handles all restricted license applications, including the Special Ignition Interlock Restricted Driver License. Arizona law mandates SR-22 filing for most suspension-triggering violations, and the SR-22 requirement typically extends for three years from the reinstatement date.
How Much Does Car Insurance Cost in Arizona?
Arizona SR-22 rates for suspended drivers average $145–$220 per month for state minimum liability, but school-commuting students under 21 often pay 25–40% more due to age-based risk factors. Ignition interlock device rental adds $70–$100 per month on top of insurance premiums. Metro Phoenix and Tucson drivers pay higher rates than rural areas due to accident frequency and theft rates.
What Affects Your Rate
- Students under 21 with SR-22 status pay 30–50% more than drivers over 25 due to age-based risk scoring combined with violation history.
- Phoenix and Tucson ZIP codes carry 15–25% higher premiums than rural Arizona due to accident frequency, theft rates, and uninsured motorist density.
- DUI suspensions trigger higher rate increases (60–120%) than point-accumulation suspensions (40–70%) because insurers view alcohol-related violations as predictive of future claims.
- Ignition interlock device installation costs $70–$150, plus $70–$100 per month for monitoring and calibration, adding approximately $1,000–$1,350 annually to your total cost.
- Drivers with a lapse in coverage before suspension face an additional 20–35% surcharge because the lapse signals higher risk to insurers.
- Students maintaining a 3.0 GPA or higher may qualify for good-student discounts that offset 8–15% of the SR-22 surcharge at carriers like State Farm, Farmers, and Allstate.

Special Ignition Interlock Restricted Driver License (SIIRDL)
Arizona's restricted license program for suspended drivers who need to drive to school, work, or medical appointments. Requires ignition interlock device installation, proof of school enrollment and class schedule, SR-22 insurance, and MVD approval.
Non-Owner SR-22 Insurance
Liability-only policy for suspended drivers who don't own a vehicle but need SR-22 filing to apply for a SIIRDL. Covers you when driving a borrowed vehicle or a parent's car to campus.
Under-21 SR-22 Filing
SR-22 insurance for drivers under 21 who face suspension and need coverage to maintain school transportation. Premiums run 30–50% higher than adult rates due to age-based risk scoring.
Liability Insurance for Students
Standard auto liability coverage required for all Arizona drivers. Students on a family policy can often stay on that policy even after suspension, though the SR-22 filing will increase the entire family's premium.
Family Policy with Restricted-License Endorsement
Adding a suspended student driver to a parent's existing Arizona auto policy with SR-22 endorsement. The student's SR-22 status increases the family's premium, but sharing a policy is usually cheaper than the student buying standalone coverage.
