No, Arizona is not a no-fault state for car accidents. It’s an at-fault (tort) state, which means the driver who caused the crash is financially responsible for the other party’s injuries, vehicle damage, and related losses. You can pursue the at-fault driver’s liability insurer directly instead of turning to your own policy first, and Arizona places no threshold on your right to file a lawsuit.
What Being an At-Fault State Actually Means
In an at-fault system, the person whose carelessness caused the collision owes the other party’s losses: medical bills, lost wages, vehicle repairs, and pain and suffering. The at-fault driver’s liability insurance is the primary source of payment, and proving negligence is a prerequisite to collecting.
No-fault states work differently. Each driver’s own insurer pays their initial medical expenses through Personal Injury Protection (PIP) coverage regardless of who caused the wreck, and lawsuits against the other driver are restricted unless injuries clear a statutory threshold. Arizona has no PIP requirement and no such threshold. If another driver’s negligence hurt you, you can go after them directly.
That distinction shapes almost everything about how a claim unfolds here. You’ll be dealing with the other driver’s insurer, not your own, for the bulk of your losses. That insurer’s job is to pay as little as possible, and the adjuster will investigate fault before agreeing to anything.
You Can Still Recover Even If You Were Partly at Fault
Arizona follows a pure comparative negligence rule. A jury reduces your total compensation by whatever percentage of blame belongs to you, but there is no cutoff. If you suffered $50,000 in damages and were 40% responsible, you’d collect $30,000. You could be 80% or even 99% at fault and still recover the remaining sliver.1Arizona Legislature. Arizona Code 12-2505 – Comparative Negligence; Definition
The only exception is intentional conduct. If you deliberately caused or contributed to the crash, you forfeit any right to compensation.1Arizona Legislature. Arizona Code 12-2505 – Comparative Negligence; Definition
This rule matters more in practice than people expect. Insurance adjusters routinely argue that the injured driver shares some blame, even in what looks like a clear rear-end collision. Every percentage point of fault they pin on you shaves money off their payout, so expect them to look for it.
How Fault Gets Sorted Out
Adjusters and courts assemble fault from whatever evidence exists. The police report carries significant weight because it captures the officer’s observations, witness statements, and any citations issued at the scene. A citation for running a red light or following too closely is a strong indicator, though not the final word on liability. Photos, skid marks, vehicle damage patterns, and any surveillance or dashcam footage all feed into the analysis, and eyewitness accounts can tip an ambiguous case.
Arizona law requires officers to complete a written accident report when a collision involves any bodily injury, a fatality, property damage above $2,000, or the issuance of a citation.2Arizona Legislature. Arizona Code 28-667 – Written Accident Report; Definition Below that threshold, if police weren’t called, your own photos and witness contact information are what you’ll have to work with.
If you disagree with the insurer’s fault assessment, you’re not stuck with it. You can dispute it or ultimately let a jury decide.
How to Actually Get Paid After a Crash
Third-Party Claim Against the At-Fault Driver’s Insurer
The most common route is filing a third-party claim with the at-fault driver’s liability insurer. You submit evidence of the other driver’s fault along with documentation of your losses: medical records, repair estimates, and proof of missed work. If the insurer accepts liability, it makes a settlement offer. Most claims resolve this way without a courtroom.
A Claim Under Your Own Policy
You can also use your own coverage while the third-party claim plays out. Collision coverage pays for your vehicle repairs minus your deductible, regardless of fault. Medical Payments coverage (MedPay) reimburses medical expenses up to your policy limit, again without regard to who caused the crash. Both get money in your hands faster than waiting on the other driver’s insurer, and your company can then seek reimbursement from the at-fault party’s insurer.
Arizona insurers are prohibited from raising your premiums because of an accident you didn’t cause or significantly contribute to.3Arizona Department of Insurance and Financial Institutions. Automobile Insurance Filing a claim after being hit by someone else shouldn’t trigger a rate increase, though it’s worth confirming your insurer’s practices before you file.
A Lawsuit
When negotiations stall or the insurer disputes fault or undervalues your injuries, filing a lawsuit is the remaining option. Litigation is slower and more expensive, but it puts the decision in front of a jury rather than an adjuster. Many cases still settle after a lawsuit is filed but before trial.
You Have Two Years to Sue
Arizona gives you two years from the date of the accident to file a personal injury or property damage lawsuit. If the injured person dies from crash-related injuries, the two-year clock starts on the date of death instead.4Arizona Legislature. Arizona Code 12-542 – Injury to Person; Injury When Death Ensues
Miss that deadline and the court will almost certainly dismiss your case, no matter how strong it is on the facts. Two years sounds generous, but medical treatment often drags on for months and building a solid claim takes time. Waiting until the last few weeks is a common and avoidable mistake. The statute of limitations technically governs lawsuits rather than insurance claims, but your leverage in negotiations disappears once that window closes.
Required Coverage in Arizona
Every Arizona driver must carry liability insurance with at least these minimum limits:5Arizona Legislature. Arizona Code 28-4009 – Motor Vehicle Liability Policy Requirements
- $25,000 for bodily injury or death of one person per accident
- $50,000 for bodily injury or death of two or more people per accident
- $15,000 for property damage per accident
These minimums, often written as 25/50/15, have been in effect since July 2020. A single emergency room visit can blow past $25,000, and a totaled late-model vehicle can easily exceed $15,000 on its own. The minimums keep a driver legal without necessarily keeping anyone protected.
Uninsured and Underinsured Motorist Coverage
Arizona law requires every auto insurer to offer uninsured motorist (UM) and underinsured motorist (UIM) coverage in writing, but you aren’t required to buy it.6Arizona Legislature. Arizona Code 20-259.01 – Motor Vehicle Liability Policy; Uninsured Optional; Underinsured Optional UM pays your damages when the at-fault driver has no insurance. UIM kicks in when the at-fault driver has insurance but not enough to cover your losses.
Roughly one in eight Arizona drivers is uninsured. If one of them hits you and you don’t carry UM coverage, you’re chasing an individual who by definition couldn’t afford insurance. If you do need to file a UM or UIM claim, Arizona law requires you to notify your insurer in writing within three years of the accident.7Arizona Legislature. Arizona Code 12-555 – Uninsured and Underinsured Motorist Coverage; Claims; Time Limits
When the At-Fault Driver Has Nothing
The at-fault system works well when the responsible driver carries adequate insurance. It works far less well when they don’t. If the at-fault driver is uninsured and has no meaningful assets, a judgment against them is a piece of paper.
Your realistic options in that scenario live inside your own policy. UM coverage is the primary safety net. Collision handles the vehicle. MedPay covers immediate medical bills. Without those, you may end up absorbing the costs yourself. Arizona’s financial responsibility laws penalize the uninsured driver, but those penalties don’t put money in your pocket.
