Below you’ll find the essentials—plus insider tips from Phoenix Arizona Insurance, protecting Valley drivers since 1992.
Key Takeaways
- Arizona mandates 15/30/10 liability plus $10k property‑damage coverage.
- Driving uninsured can trigger fines up to $1,000 and 12‑month license suspension.
- Uninsured‑motorist (UM/UIM) protection is optional but strongly recommended.
- Collision + comprehensive guard your own vehicle; higher deductibles lower premiums.
- Clean records, bundling and defensive‑driving courses unlock 10 – 25 % discounts.
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
- 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?
- Driving record – accidents or tickets within 3 years raise rates 20‑40 %.
- Vehicle type – repair cost, theft rate and horsepower matter.
- Credit‑based insurance score – better credit usually earns lower premiums.
- Annual mileage – telematics or low‑mileage programs cut costs for short commutes.
- 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.
