Arizona law requires every driver to carry Arizona minimum auto insurance under A.R.S. § 28-4009. The state minimum is 25/50/15, which means $25,000 per person, $50,000 per accident, and $15,000 in property damage. The problem is that the average new vehicle in 2026 costs over $47,000. That $15,000 property damage limit covers less than one-third of it.
At Cook Insurance in Apache Junction, we have been helping Arizona families and small business owners understand their coverage options since 1977. This guide breaks down exactly what the state requires, what those numbers mean in a real claim, and where most drivers end up underinsured without realizing it. For the broader picture of coverage types and rate factors, see our complete auto insurance guide.

What Are the Minimum Auto Insurance Requirements in Arizona?
Arizona requires every driver to carry liability insurance that meets the following limits:
- $25,000 per person for bodily injury
- $50,000 per accident for total bodily injury
- $15,000 per accident for property damage
This is commonly written as 25/50/15 and referred to as the state minimum. Under A.R.S. § 28-4009, these are the legal floors. They are not recommendations or averages. They are the legal minimum every registered vehicle must carry to operate on Arizona roads.
Liability insurance covers injuries and property damage you cause to other people. It does not pay for your own medical bills or repairs to your own vehicle. Collision and comprehensive coverage is separate and optional under Arizona law, though lenders typically require it if you are financing or leasing a vehicle.
What Does 25/50/15 Actually Mean?
These three numbers represent three separate coverage limits within your liability policy.
$25,000 per person for bodily injury is the maximum your insurance will pay toward one injured person's medical bills, lost wages, and pain and suffering in an accident you caused. If that person's costs exceed $25,000, which is common after a hospital stay, you are personally responsible for the difference.
$50,000 per accident for bodily injury is the total your policy pays across all injured parties in one accident. If you rear-end a vehicle carrying three people and each has $25,000 in medical expenses, your policy covers $50,000 total. The remaining $25,000 comes from you directly.
$15,000 per accident for property damage pays for damage to other people's vehicles and property. In 2026, the average new car transaction price in the United States is above $47,000. A $15,000 property damage limit covers roughly one-third of one new vehicle. If you total someone's truck, you pay the rest out of pocket.
| Coverage Type | AZ Minimum Limit | Real-World Gap |
|---|---|---|
| Bodily Injury (per person) | $25,000 | Emergency room and surgery can exceed this easily |
| Bodily Injury (per accident) | $50,000 | Multi-passenger accidents exceed this fast |
| Property Damage | $15,000 | Average new vehicle costs $47,000+ |
Why Arizona's Minimum Coverage Is Often Not Enough
Meeting the legal minimum keeps your registration valid and avoids fines. It does not necessarily protect your finances if you cause a serious accident.
Arizona sees heavy traffic on corridors like the US-60, Loop 202, and State Route 24 connecting Apache Junction to Mesa and the broader East Valley. Multi-vehicle accidents on these roads can generate claims that far exceed what a minimum policy pays. When your insurance runs out, injured parties can pursue the remaining amount from your personal assets, including your savings, your vehicle, and in some cases your wages.
There are three scenarios where state minimums routinely fall short:
New or financed vehicles:
If the other driver is in a newer vehicle, $15,000 in property damage coverage will not come close to covering the repair or replacement cost. You pay the difference directly.
Accidents with multiple passengers:
The $50,000 bodily injury cap covers all injured parties combined. Three injured passengers with moderate injuries can easily exceed that limit without any of them being critically hurt.
Serious injuries with long recovery:
Physical therapy, specialist visits, and lost wages add up quickly. A $25,000 per-person limit disappears after a few weeks of serious medical care.
Most insurance professionals recommend at least 100/300/100 in liability limits as a practical baseline. That is four times the state minimum. Many also suggest adding an umbrella policy on top of that for added protection.
Penalties for Driving Without Insurance in Arizona
Arizona enforces its insurance requirements. If you are caught driving without the required minimum coverage, the consequences move quickly from inconvenient to serious.
A first-time offense results in a suspended driver's license and vehicle registration. You will also be required to file an SR-22 with the Arizona Department of Transportation for three years. An SR-22 is a certificate of financial responsibility, and this filing alone typically increases your insurance premiums significantly.
Additional penalties include:
- A fine of up to $500 for a first offense
- Up to $1,000 for subsequent offenses
- Potential vehicle impoundment
- Mandatory license reinstatement fees after the suspension period
Driving without insurance is not worth the savings on premiums. The financial and legal consequences of even one traffic stop without valid coverage exceed years' worth of premium payments.
What About Uninsured and Underinsured Motorist Coverage?
Arizona does not require drivers to carry uninsured motorist (UM) or underinsured motorist (UIM) coverage, but insurers are required to offer it. That distinction matters.
Arizona has one of the higher shares of uninsured drivers in the country. According to the Insurance Information Institute, roughly 12% of Arizona drivers carry no insurance at all. If an uninsured driver hits you and causes injuries, your own liability coverage does not help you. It only covers damage you cause to others.
Uninsured motorist coverage pays your medical bills and related costs when the at-fault driver has no insurance. Underinsured motorist coverage does the same when the other driver has insurance, but their limits are not high enough to cover your damages.
These coverages protect you and your passengers. Given the number of uninsured drivers in Arizona, skipping them in exchange for a lower premium is a risk that frequently backfires.
Does Arizona Use a No-Fault or At-Fault System?
Arizona is an at-fault state, which means the driver who caused the accident is financially responsible for the resulting damages. This is sometimes called a tort system.
Under this model, if another driver hits you, you file a claim against their liability insurance. If you caused the accident, your liability insurance responds. You do not automatically file against your own insurer the way you would in a no-fault state.
This structure makes adequate liability coverage especially important. When you are at fault, your insurance is the only thing standing between your personal finances and the other party's claims. Low liability limits mean your insurer pays up to the limit, and then you are on your own for anything above that.
It also means that when someone else is at fault and underinsured, your only recourse is their limited policy plus your own underinsured motorist coverage. That is another strong reason to carry it.
Required vs. Recommended Coverage: A Side-by-Side Look
| Coverage | AZ Minimum Required | What Professionals Often Recommend |
|---|---|---|
| Bodily Injury (per person) | $25,000 | $100,000 |
| Bodily Injury (per accident) | $50,000 | $300,000 |
| Property Damage | $15,000 | $100,000 |
| Uninsured Motorist | Not required | Strongly recommended |
| Collision | Not required | Required if financed |
| Comprehensive | Not required | Required if financed |
| Medical Payments | Not required | Helpful gap coverage |
The difference in premium between minimum coverage and 100/300/100 is often smaller than people expect. It is frequently less than $15 to $30 per month, while the difference in protection is significant.
If you are not sure what coverage you currently carry or whether your limits are realistic for your situation, Cook Insurance can review your existing policy at no cost and compare rates across multiple carriers to find you better protection at a price that makes sense.
Why Cook Insurance Is the Right Choice for Arizona Auto Coverage
FAQs About Arizona Auto Insurance Requirements
Does Arizona require PIP (personal injury protection) coverage?
No. Arizona does not require personal injury protection. As an at-fault state, the driver responsible for an accident is liable for the other party's damages. Medical payments coverage (MedPay) is an optional add-on that can cover your own injuries regardless of fault, and we often recommend it as a practical gap filler. The Arizona DIFI's consumer resources cover how MedPay and UM/UIM interact.
Can I show proof of insurance digitally in Arizona?
Yes. Arizona accepts electronic proof of insurance on a mobile device. You are not required to carry a paper card, though having a physical copy in your vehicle is never a bad idea if your phone battery dies.
What happens if my coverage lapses even briefly?
A lapse in coverage, even for a day, can trigger a suspension of your license and registration in Arizona. Reinstating both requires fees and often an SR-22 filing. Continuous coverage, even at minimum levels, avoids these consequences.
Does the 25/50/15 requirement apply to motorcycles?
Yes. Motorcycles registered in Arizona are subject to the same minimum liability limits as passenger vehicles under A.R.S. § 28-4009. Many riders choose higher limits given the increased injury risk motorcyclists face in accidents.
What is SR-22 and when do I need it?
An SR-22 is a certificate your insurer files with the Arizona MVD confirming you carry the required minimum insurance. It is typically required after a DUI, driving without insurance, or certain license suspension events. Cook Insurance works with carriers that file SR-22 certificates.
Conclusion
Arizona law sets a clear floor for auto insurance through A.R.S. § 28-4009: 25/50/15 in liability coverage for every registered vehicle. That floor keeps you legal, but it does not guarantee you are financially protected in a serious accident. The property damage limit covers a fraction of today's average vehicle cost, and the bodily injury limits can be exhausted by a single hospitalization.
