Arizona No-Fault Insurance Laws Explained: What Every Driver Needs to Know
If you've been in a car accident in Arizona and heard the term "no-fault insurance," you may be confused — and for good reason. Arizona is not a no-fault state. It follows an at-fault (also called "tort") system. That distinction matters a lot when it comes to who pays your medical bills and how you file a claim.
This guide breaks down exactly how Arizona's car accident insurance laws work, what minimums you need to carry, and what your options are after a crash.
What Is the Difference Between No-Fault and At-Fault States?
In a no-fault state, each driver turns to their own insurance first after an accident — regardless of who caused it. Your personal injury protection (PIP) coverage pays your medical bills up to a limit, and in many no-fault states you can only sue the other driver in serious cases.
In an at-fault state like Arizona, the driver who caused the accident is legally responsible for the damages. That means:
- You can file a claim directly against the at-fault driver's liability insurance.
- You can sue the at-fault driver in civil court.
- There is no requirement to carry PIP coverage (though you can add it).
This is an important distinction. If someone else caused your crash, you have the right to pursue compensation from them — not just your own insurer.
Arizona's Minimum Insurance Requirements
Arizona law (A.R.S. § 28-4009) requires all registered drivers to carry liability insurance at these minimum limits:
- $25,000 per person for bodily injury
- $50,000 per accident for bodily injury (when multiple people are hurt)
- $15,000 per accident for property damage
These are often written as 25/50/15. Keep in mind these are minimums. A serious accident can easily exceed these limits, leaving the at-fault driver personally liable for the difference.
Drivers are also encouraged — though not required — to carry:
- Uninsured/Underinsured Motorist (UM/UIM) coverage — protects you if the at-fault driver has no insurance or not enough
- Medical Payments (MedPay) coverage — covers your medical bills regardless of fault
- Collision coverage — pays for your vehicle repairs regardless of fault
How Fault Is Determined in Arizona
Arizona follows a pure comparative fault rule (A.R.S. § 12-2505). This means:
- If you were partially at fault for the accident, your compensation is reduced by your percentage of fault.
- Even if you were 99% at fault, you could still technically recover 1% of your damages.
- Insurance adjusters and courts look at police reports, witness statements, photos, and other evidence to assign fault percentages.
This system is more plaintiff-friendly than some states, but insurers will still use your partial fault to reduce what they pay you. Having documentation on your side — and potentially a personal injury attorney — can make a significant difference.
What Happens If the Other Driver Has No Insurance?
Arizona has a significant uninsured motorist problem. If the driver who hit you has no insurance, your options include:
- Your own UM/UIM coverage — if you purchased it, this is your first line of defense.
- MedPay coverage — can cover immediate medical costs.
- Filing a lawsuit — you can sue an uninsured driver personally, though collecting can be difficult if they lack assets.
This is exactly why UM/UIM coverage is strongly recommended, even though Arizona doesn't require it. Talk to our intake team to understand your options if you were hit by an uninsured driver.
Arizona's Statute of Limitations for Car Accident Claims
Time matters. Under A.R.S. § 12-542, Arizona gives you two years from the date of the accident to file a personal injury lawsuit. For property damage, the limit is also two years.
Missing this deadline almost always means losing your right to recover compensation — regardless of how strong your case is. If the accident involved a government vehicle or a city/county entity, different (shorter) notice deadlines may apply.

FAQ: Arizona Car Accident Insurance Questions
H3: Is Arizona a no-fault state?
No. Arizona is an at-fault state. The driver who caused the accident is responsible for damages. You can file a claim against their liability insurance or pursue a lawsuit.
H3: Do I need PIP (Personal Injury Protection) coverage in Arizona?
No, PIP is not required in Arizona. However, you can purchase MedPay coverage, which serves a similar purpose — covering medical bills after a crash regardless of who was at fault.
H3: What if the other driver was partially at fault and so was I?
Arizona's pure comparative fault rule means you can still recover damages even if you share some blame. Your total compensation is reduced by your percentage of fault. For example, if you were 20% at fault and your damages totaled $100,000, you could recover up to $80,000.
H3: How long do I have to file a claim in Arizona?
Generally, two years from the date of the accident for personal injury and property damage claims. Special rules may apply if a government entity is involved. Confirm your specific deadline with an attorney.
H3: Should I accept the insurance company's first settlement offer?
This is a personal decision, but it's worth knowing that first offers are often lower than what you may ultimately be entitled to. Consulting a personal injury attorney before accepting any settlement is a smart step — most offer free consultations.
Know Your Rights After an Arizona Car Accident
Arizona's at-fault system gives you real options to recover compensation from the driver who caused your crash. But the process — dealing with insurance adjusters, proving fault, and calculating damages — can be complicated, especially when you're also healing from injuries.
Understanding the basics is a strong first step. The next step is finding out whether your specific situation gives you a strong path forward.
