Arizona car insurance requirements and laws

Minimum car insurance requirements

Arizona requires liability coverage of at least 25/50/15 on every policy issued or renewed since July 1, 2020, when the state raised its minimums from 15/30/10 (A.R.S. § 28-4009). That means $25,000 for injuries to one person, $50,000 for all injuries in one crash and $15,000 for damage to other people's property. The state car insurance requirements lookup compares Arizona with other states, and what 25/50/25 means: split liability limits explained explains the notation.

The $15,000 property damage minimum is low compared with what vehicles cost to repair or replace. If you cause a crash that totals a $35,000 SUV, a minimum policy pays $15,000 and the owner (or their insurer) can come after you for the other $20,000. On the injury side, if you cause a crash and one person has $40,000 in medical bills, your policy pays $25,000 and leaves $15,000 for which you can be sued. how much liability coverage do you need? and the How much car insurance do I need? help you pick limits that protect your savings and wages.

You must keep evidence of insurance in the vehicle, and Arizona law lets you show it on a phone; doing so does not give police permission to look at anything else on the device (A.R.S. § 28-4135).

Fault system and what it means after a crash

Arizona is an at-fault state. The driver who caused the crash, through their liability insurer, pays for the other side's injuries and vehicle damage. You can claim against that insurer, claim under your own collision coverage, or file suit. See no-fault vs at-fault states.

Arizona uses pure comparative negligence (A.R.S. § 12-2505). If you share the blame, your damages shrink by your percentage of fault but are never wiped out. A driver found 40% responsible for a $10,000 loss can still recover $6,000 from the other driver. how fault is determined in a car accident covers the evidence adjusters rely on.

Lawsuits for injuries and for property damage generally must be filed within two years (A.R.S. § 12-542). See statutes of limitations for car accident claims, and talk to an Arizona attorney about your specific deadline.

Optional coverage worth considering here

• Uninsured and underinsured motorist. Insurers must offer UM and UIM in writing on a form approved by the state, at limits up to your bodily injury limits. If you decline, that choice carries over to renewals. The Insurance Research Council estimates about 10.6% of Arizona drivers were uninsured in 2023, but underinsured drivers carrying only the minimum are a bigger risk when injuries are serious. See uninsured and underinsured motorist coverage explained and underinsured motorist coverage.
• Comprehensive. Monsoon hail, dust storms, flash floods and vehicle theft are comprehensive claims. Many Arizona insurers offer full glass coverage for windshields cracked by road debris; see full glass coverage and zero-deductible windshield repair.
• Collision. Pays to repair your own car regardless of fault and is required by lenders on financed vehicles.
• Medical payments. medical payments coverage pays your medical bills up to a set limit regardless of fault.
• Higher property damage limits. Raising the $15,000 floor is usually inexpensive compared with the exposure.

What drives rates in Arizona

The NAIC's latest data put Arizona's average annual expenditure at $1,344 in 2023, above the national average of $1,282. These averages blend all policy types and do not predict an individual quote (What NAIC auto insurance data measures).

Rates in Arizona reflect fast population growth and heavy traffic in the Phoenix and Tucson metro areas, long commutes at highway speeds, and comprehensive losses from summer storms and theft. Repair costs have climbed with newer vehicles that carry sensors and cameras (driver-assistance sensors and the cost of repairs). Insurers in Arizona may use credit-based insurance scores, and your ZIP code makes a large difference between urban and rural areas (Why your ZIP code changes your car insurance price).

Penalties for driving uninsured

Arizona treats a lapse in required coverage as a civil violation with real consequences (A.R.S. § 28-4135):

• First violation: a minimum civil penalty of $500, plus a three-month suspension of your driving privileges, or a restricted license once the state verifies you have insurance.
• Second violation within 36 months: a minimum $750 penalty and a six-month suspension of your license and the vehicle's registration and plates.
• Later violations: higher penalties and longer suspensions.

A citation for failing to show proof can be dismissed if you prove to the court that you were insured when cited. See penalties for driving without insurance.

SR-22 and high-risk drivers

The Arizona Motor Vehicle Division can require an SR-22, a certificate your insurer files to prove you carry at least the minimum coverage, after serious violations such as DUI or driving uninsured. MVD sets how long you must keep it on file, and a lapse can trigger a new suspension. SR-22 insurance explained explains the process, and Car insurance after a DUI covers pricing after an impaired-driving conviction. Drivers turned away by standard carriers can try nonstandard auto insurers: who they serve and what to watch; see also high-risk car insurance: options when insurers say no.
