Arizona law requires every driver to carry minimum liability auto insurance of 25/50/15. That is $25,000 in bodily injury per person, $50,000 per accident, and $15,000 in property damage. Most drivers know they need it. Almost no one knows what those numbers actually mean when something goes wrong. Here is the plain-English version.

What the 25/50/15 numbers actually mean

If you cause an accident in Arizona, your liability insurance pays the other party for injuries and damage you caused. With state minimum coverage:
  • Up to $25,000 to any one person injured
  • Up to $50,000 total across all injured people in the accident
  • Up to $15,000 in property damage (the other car, fences, mailboxes)
If the bill exceeds those limits, you personally owe the rest. The other driver’s insurance company will sue you, and they will win.

A real-world example

You rear-end a 2024 Lexus on the 101 at low speed. The car needs $18,000 in repairs. Within your $15,000 property damage limit, you cover the $3,000 gap. The driver has minor whiplash and racks up $32,000 in medical bills. Within your $25,000 limit, you cover the $7,000 gap. Total out of pocket: $10,000. That is a low-end accident. A high-end accident, an injury that requires surgery and rehab, can easily run $100,000 to $250,000. Your $25,000 limit covers a fraction of that. The rest comes from your savings, your home equity, and your future wages.

Uninsured motorist coverage: the part Arizona drivers really need

Arizona has one of the highest rates of uninsured drivers in the country. Roughly 12 percent of drivers on the road have no insurance at all. If one of them hits you, your minimum policy does nothing. You can sue them, but you cannot get blood from a stone. Uninsured motorist (UM) coverage protects you when the at-fault driver has no insurance or cannot pay. It is inexpensive, usually $50 to $150 a year for solid coverage, and it is the single most important add-on for any Arizona driver.

What we recommend for most Arizona drivers

  • Bodily injury liability: 100/300 (instead of 25/50)
  • Property damage liability: $100,000 (instead of $15,000)
  • Uninsured/underinsured motorist: matching limits to your liability
  • Medical payments coverage: $5,000 to $10,000
  • Comprehensive and collision: with deductibles you can afford
The cost difference between state minimum and the recommended auto coverage above is usually $200 to $400 per year. The protection difference is potentially millions of dollars.

How to check your current policy in 5 minutes

Pull out your declarations page (the first page of your policy). Look for the liability limits line. It will read something like “25/50/15” or “100/300/100.” If you see numbers smaller than 100/300/100, call us for a free policy review. We will tell you exactly what you are covered for and what you are not.

What the Arizona minimum car insurance numbers actually mean

The Arizona state minimum car insurance reads as 25/50/15. Most drivers see those numbers, sign the policy, and move on. Here is what each one really represents the moment a serious accident happens. 25 = $25,000 per person, bodily injury liability. This is the absolute maximum your policy will pay for any single person you injure. A typical ambulance ride and one ER visit can hit $20,000. A broken leg with surgery is $40,000 to $80,000 before any rehabilitation. Once your policy is exhausted, the rest is on you personally. 50 = $50,000 total bodily injury per accident. This is split across everyone you injured. A two-car accident with three injured people splits $50,000 three ways. If one of them is seriously hurt, the math runs out fast. 15 = $15,000 property damage liability. This is what pays to repair or replace anything you hit, mostly other vehicles. The average new vehicle on Arizona roads in 2026 costs $48,500. A single fender-bender with a new SUV often blows through $15,000 just on the bumper, sensors, and paint.

Why Arizona minimum car insurance falls short most often

Three common Arizona scenarios that minimum coverage cannot handle:
  • Multi-vehicle freeway pile-up. Arizona has miles of 75 mph freeway. A chain-reaction accident easily involves three or more vehicles. $15,000 of property damage liability covers roughly one luxury vehicle, not three.
  • Hospitalization of the other driver. Even a single overnight ICU stay in Phoenix runs $30,000 to $60,000. Your $25,000 per-person limit is exhausted before discharge.
  • Uninsured motorist hits you. Roughly 12 percent of Arizona drivers are uninsured. State minimum has no uninsured motorist protection unless you add it. If you are hit, your only option is to sue someone who has no money.

What Arizona drivers should actually carry

For most Scottsdale, Phoenix, and Valley clients we work with, the right baseline is 100/300/100 plus uninsured motorist matching your limits, plus collision and comprehensive on any vehicle worth more than $5,000. Translated:
  • $100,000 per person bodily injury
  • $300,000 total per accident
  • $100,000 property damage liability (covers most luxury SUVs and most light commercial vehicles)
  • Uninsured / underinsured motorist at 100/300
  • Collision and comprehensive with $500 or $1,000 deductible
  • Medical payments coverage of $5,000 to $10,000
The price difference between 25/50/15 and 100/300/100 is usually $200 to $350 a year, sometimes less. The protection difference is hundreds of thousands of dollars and your savings, your home, and your wages.

When Arizona minimum car insurance is actually fine

There is exactly one situation where state minimum makes sense: you drive an older vehicle worth under $3,000, you have very little net worth to protect, and you have no assets a court could come after. Even then, the uninsured motorist gap means you should at least add UM/UIM coverage. It is inexpensive and covers your medical bills if the other driver has nothing.
