Arizona Auto‑Insurance Laws at a Glance

The Arizona Department of Transportation requires every motorist to prove financial responsibility. Most drivers meet this rule with an auto‑insurance policy, but you can also post a $40,000 certificate of deposit—impractical for most.

Minimum Liability Limits

Coverage Minimum Limit What It Pays For
Bodily Injury (per person) $15,000 Medical bills of one injured party
Bodily Injury (per accident) $30,000 All injuries in single crash
Property Damage $10,000 Vehicle & object repairs

These figures are bare‑bones. Fender‑bender repairs and ER visits often exceed $10k and $15k, so many drivers raise limits to 100/300/100 or higher for realistic protection.

Coverage Options Beyond the Minimum

optional auto insurance coverages in arizona
  • Collision – fixes or replaces your own car after a crash.
  • Comprehensive – covers theft, vandalism, hail, animals or falling objects.
  • Uninsured / Under‑insured Motorist – pays when the at‑fault driver has little or no insurance.
  • Medical Payments – immediate medical bills regardless of fault; complements health insurance.
  • Rental Reimbursement & Roadside – keeps you moving after covered losses.

Why Liability Limits Matter

Arizona allows injured parties to sue for amounts beyond your policy limits. Example: a two‑car crash with serious injuries can easily top $100k in medical costs, leaving under‑insured drivers personally responsible. Upping limits is often less than $8 per month.

Uninsured‑Motorist (UM/UIM) Protection

Roughly 12 % of Arizona motorists carry no insurance. UM covers your medical costs when they hit you; UIM kicks in when their limits run out. Both are inexpensive—usually 5‑10 % of your premium—and prevent costly lawsuits or wage garnishments.

Collision & Comprehensive

Newer vehicles or leased/financed cars almost always require these coverages. Tip: choose a deductible you could pay tomorrow without dipping into emergency savings—common choices are $500 or $1,000.

What Drives Your Premium?

  1. Driving record – accidents or tickets within 3 years raise rates 20‑40 %.
  2. Vehicle type – repair cost, theft rate and horsepower matter.
  3. Credit‑based insurance score – better credit usually earns lower premiums.
  4. Annual mileage – telematics or low‑mileage programs cut costs for short commutes.
  5. Location – urban ZIPs face higher theft and crash rates than rural areas.

Quick Tips to Choose Smart Coverage

Step Action
1 List assets (home, savings) to decide liability limits.
2 Quote three carriers with identical limits & deductibles.
3 Ask about multi‑policy, pay‑in‑full, defensive‑driving discounts.
4 Opt for UM/UIM and at least $100k property‑damage limit.
5 Review coverage every 12 months or after major life changes.

Penalties for Driving Uninsured

  • First offense: $500 fine + license & registration suspended 3 months.
  • Second offense: $750 fine, 6‑month suspension, SR‑22 filing for 3 years.
  • Accident while uninsured: unlimited personal liability for injuries & damage.
