Is Arizona a No-Fault State?

Is Arizona a no-fault state?

No. Arizona is an at-fault state — also called a tort state. The driver who causes a crash is legally responsible for the harm it does, and their liability insurance pays for the other side's injuries, lost wages, and vehicle damage. Arizona has no personal injury protection (PIP) requirement and never has.

That one word — fault — shapes everything that happens after an Arizona crash: who you file the claim with, what you can recover, and why proving what happened matters so much. Here is how the system actually works.

What do no-fault states do differently?

In a no-fault state — Florida and Michigan are the well-known examples — every driver carries PIP coverage, and after a crash each driver's own policy pays their initial medical bills and lost wages regardless of who caused it. The trade-off is a lawsuit restriction: you generally cannot sue the at-fault driver for pain and suffering unless your injuries cross a statutory threshold.

Arizona rejected that model. There is no PIP mandate, no threshold, and no restriction on suing the person who hurt you. You claim against the at-fault driver's insurer from day one, and you can recover the full measure of your damages — medical bills, lost income, and pain and suffering — with no artificial cap. The Arizona Constitution actually prohibits damage caps in injury cases (Ariz. Const. art. 2, § 31).

At-fault vs. no-fault — what changes in practice?

Question	At-fault (Arizona)	No-fault states
Who pays your injury bills first	The at-fault driver's liability insurer	Your own PIP coverage
Is PIP required	No — Arizona has no PIP mandate	Yes
Can you sue the at-fault driver	Yes, with no injury threshold	Only above a statutory threshold
Pain and suffering	Recoverable in any injury claim	Restricted to serious-injury cases
Does proving fault matter	It decides the whole claim	Less, for the initial benefits

What does at-fault mean after a Phoenix crash?

It means your claim runs against the other driver's insurance company, not your own. You (or your lawyer) present evidence of what happened — the police report, photos, witness statements — and the at-fault driver's insurer pays for your treatment, your lost wages, and your pain and suffering, up to its policy limits.

It also means the fight is over fault itself. The other insurer's adjuster is paid to shift blame onto you, because every percentage point of fault they pin on you is money they keep. That is true whether the crash happened downtown or in Tempe, and it is the single biggest reason represented claimants tend to do better. How Arizona decides fault — evidence, police reports, adjuster tactics — is its own topic; related reading: how fault is decided in Arizona.

What if you were partly at fault?

You can still recover. Arizona follows pure comparative negligence under A.R.S. § 12-2505: your recovery is reduced by your percentage of fault but is never barred. A driver found 20% at fault still recovers 80% of their damages — and even a driver found 90% at fault can recover the remaining 10%.

Insurers know this, which is why "you were partly to blame" is their favorite argument. It is an opening position, not a ruling. Push back with evidence and the percentage moves.

What insurance does Arizona require instead of PIP?

Every Arizona driver must carry liability coverage of at least $25,000 bodily injury per person, $50,000 per crash, and $15,000 property damage — the 25/50/15 minimums under A.R.S. § 28-4009. Insurers must also offer uninsured and underinsured motorist coverage under A.R.S. § 20-259.01; UM/UIM is optional, but it is what protects you when the at-fault driver has little or no insurance. The full breakdown is in our guide to Arizona car insurance requirements.

How long do you have to bring an at-fault claim?

Two years from the crash, under A.R.S. § 12-542. If a city, county, or state vehicle or road is involved, a notice of claim must be served within 180 days under A.R.S. § 12-821.01, with suit filed within one year. In practice the useful deadlines are shorter: camera footage gets overwritten and witnesses scatter within weeks.

The practical checklist after any Arizona crash:

1. Get medical care first — gaps in treatment become the insurer's argument later.
2. Report the crash and get the report number; the police report is the fault fight's first exhibit.
3. Photograph vehicles, the scene, and your injuries before anything is repaired or healed.
4. Notify your own insurer, but give no recorded statement to the other driver's insurer.
5. Get a case value estimate before accepting anything — start with the personal injury calculator or a free consultation.

Cases with serious injuries, disputed fault, or a rideshare vehicle involved are exactly where the at-fault system rewards having a lawyer — the recovery turns on evidence, and evidence work is the job.

Frequently asked questions

Is Arizona a no-fault state for car accidents?

No. Arizona is an at-fault (tort) state. The driver who causes the crash is responsible for the resulting damages, and their liability insurance pays the injured party's claim. Arizona does not require PIP coverage, and there is no restriction on suing the at-fault driver for the full measure of your damages.

Whose insurance pays after a car accident in Arizona?

The at-fault driver's liability insurance pays for the other side's injuries and vehicle damage. Your own policy comes into play through optional coverages: UM/UIM if the at-fault driver is uninsured or underinsured, medical payments coverage for early bills, and collision coverage if you want your car fixed without waiting for the liability fight to resolve.

Do I have to pay my own medical bills after a crash in Arizona?

Initially, bills usually run through your health insurance or medical payments coverage while the claim is pending, because the at-fault insurer pays in one lump at settlement rather than bill by bill. At settlement, the recovery covers those bills and reimburses the insurers that advanced payment. A lawyer negotiates those paybacks down so more of the settlement stays with you.

Can I still recover if the accident was partly my fault?

Yes. Arizona's pure comparative negligence rule (A.R.S. § 12-2505) reduces your recovery by your share of fault but never eliminates it. Found 30% at fault, you still recover 70% of your damages. Insurers overstate fault percentages routinely because each point they assign to you cuts what they pay — it is negotiable, not final.

What happens if the at-fault driver has no insurance?

Your own uninsured motorist (UM) coverage steps into the at-fault driver's place and pays what their liability policy should have — that is exactly what it exists for. Arizona insurers must offer UM/UIM under A.R.S. § 20-259.01, though drivers can decline it. If you carry it, a hit-and-run is handled the same way.

Does no-fault insurance exist in Arizona at all?

Not as a required system. Arizona drivers cannot buy PIP as mandated in no-fault states, but optional medical payments (medpay) coverage works similarly on a smaller scale — it pays your medical bills regardless of fault, quickly, without a liability determination. It is a useful add-on precisely because Arizona's at-fault claims take time to resolve.
