Most Arizona drivers can tell you what they pay for car insurance, but far fewer can tell you what each line on the policy actually covers. That gap matters on the worst day, when a claim reveals that a coverage you assumed was there was never added. Understanding car insurance coverage in Arizona is the fastest way to stop paying for protection you do not need and start paying for the protection you do.
Riseson Insurance is an independent Arizona broker based in Tempe. This guide walks through each coverage type on a typical policy, what the state requires, and how to decide which limits make sense for your situation.
What car insurance coverage Arizona law requires
Arizona requires every registered vehicle to carry liability insurance. For policies issued or renewed since July 1, 2020,
A.R.S. 28-4009 sets the minimums at $25,000 for injury or death to one person, $50,000 for injury or death to two or more people, and $15,000 for property damage in one accident. Most people call this 25/50/15.
Liability pays for the harm you cause to other people and their property. It never pays to fix your own car or treat your own injuries, which is why the state minimum is a starting point rather than a complete policy.
Collision and comprehensive coverage explained
These two coverages protect your own vehicle, and they are the ones people most often confuse. Collision pays to repair or replace your car after a crash with another vehicle or an object, whether you caused it or not. Comprehensive pays for losses that are not collisions, such as theft, vandalism, fire, falling objects, broken glass and hail.
In the Valley, comprehensive earns its keep. A monsoon hailstorm, a cracked windshield from gravel on the I-10, or a stolen catalytic converter would all land here. If you finance or lease your vehicle, your lender will almost always require both coverages.
Uninsured and underinsured motorist coverage
The Insurance Information Institute estimates that roughly 13 percent of Arizona drivers are uninsured. If one of them hits you, uninsured motorist coverage pays for your injuries and, depending on the policy, your vehicle. Underinsured motorist coverage steps in when the at-fault driver has insurance but not enough of it to cover your bills.
Under
A.R.S. 20-259.01, Arizona insurers must offer both coverages, and the limits default to match your liability limits unless you decline in writing. Declining them to save a few dollars is one of the riskiest choices a driver can make.
Medical payments, rental and roadside coverage
Beyond the big four, several smaller coverages fill everyday gaps.
Medical payments helps with your own and your passengers' medical bills regardless of fault.
Rental reimbursement pays for a rental car while yours is in the shop after a covered loss.
Roadside assistance covers towing, jump starts and lockouts, which matters in July when a dead battery can strand you in 110 degree heat.
Two more worth asking about are gap coverage, which pays the difference between your loan balance and your car's value if it is totaled, and custom parts coverage for aftermarket upgrades. Each is inexpensive compared with the loss it addresses.
How much car insurance costs in Arizona by coverage level
Choosing more coverage raises the price, but the gap is not as large as many drivers expect.
Experian reported in August 2026 that Arizona drivers pay an average of about $120 per month for minimum coverage and about $212 per month for full coverage. Your own rate will differ based on your record, vehicle, ZIP code and the carrier.
We cover the factors behind those numbers in our guide to
what drives car insurance rates in Arizona. The key point here is that the extra monthly cost of full coverage is small next to a single uninsured driver claim.
How to choose the right limits and deductibles
A practical way to set limits is to ask what you would lose in a serious at-fault crash. If you own a home, have savings or earn a steady income, a lawsuit could reach those assets once the policy limit runs out, so higher liability limits protect more than just your car. Our explainer on
policy limits in home and auto insurance goes deeper on how to size them.
For deductibles, pick an amount you could pay tomorrow without stress. A higher collision deductible lowers your premium, but only if the cash is truly available when you need it. Many Riseson clients also bundle auto with home or renters to earn a multi-policy discount, which we detail in our guide to
bundling home and auto insurance in Arizona.
Frequently asked questions about car insurance coverage in Arizona
What coverage do I legally need on my car in Arizona? Arizona requires liability limits of at least 25/50/15, and you must be able to show proof of insurance if asked. That covers other people, not your own car or injuries.
What is the difference between collision and comprehensive? Collision pays for damage from a crash, while comprehensive pays for non-crash losses such as theft, hail, fire, vandalism and broken glass. Lenders usually require both on financed vehicles.
Is uninsured motorist coverage required in Arizona? It is not mandatory, but insurers must offer it, and you can only decline it in writing. With roughly 13 percent of drivers uninsured, most drivers keep it.
How much does full coverage car insurance cost in Arizona? Experian's August 2026 data lists an average of about $212 per month for full coverage, compared with about $120 for minimum coverage. Your age, record, vehicle and ZIP code set the real figure.
