Arizona Accident & Injury Laws

Everything that determines what your claim is worth in Arizona: deadlines, fault rules, and minimum insurance — with citations to the actual statutes.

The 4 rules that decide your Arizona claim

By AccidentCompass Editorial Team · Updated July 13, 2026

Arizona crash claims concentrate brutally: of the state’s 121,107 crashes in 2024, 72.7% happened in Maricopa County, and half the state’s 1,228 road deaths did too (ADOT). The law that processes those claims is unusual in three ways that cut in opposite directions — the most forgiving fault rule in the region, a constitutional ban on damage caps, and one of the country’s harshest deadlines for claims against the government. Which of the three controls your case is usually obvious within a week of the crash; here’s how each works.

Pure comparative fault: no cliff, no bar

Arizona is a pure comparative fault state (A.R.S. § 12-2505) — a genuine rarity next to Texas, Georgia, and Florida, which all zero out recovery around the 50% line. In Arizona there is no cliff. Damages of $100,000:

• 20% at fault → you recover $80,000.
• 50% at fault → you recover $50,000 — where a Georgia plaintiff gets nothing.
• 70% at fault → you still recover $30,000.

Practical consequences: in Arizona, “the crash was partly my fault” is a discount, never a death sentence — so claims that would be abandoned elsewhere are worth pursuing here, and fault fights are about size, not survival. The exception: a claimant who acted intentionally or wantonly recovers nothing. And fault is “in all cases” a jury question in Arizona — adjusters can’t dictate your percentage, only predict what a Maricopa County jury would say, which is exactly the leverage documented evidence buys.

The flip side is several-only liability (§ 12-2506): Arizona abolished joint and several liability, so each defendant pays only its own percentage — and fault can be assigned to “empty chairs,” nonparties like a fleeing driver or an out-of-reach employer. In multi-vehicle pileups, whoever identifies and joins every liable party controls how much of the verdict is actually collectible. That’s investigation work, and it’s where Arizona cases are won.

Two years to sue — 180 days if the government is involved

The general deadline is two years for injury and wrongful death (A.R.S. § 12-542). Against public entities — a city vehicle, a county road defect, a school district van, a state employee — the calendar shrinks to the harshest in the region:

Arizona courts enforce both strictly: a notice that’s late, sent to the wrong official, or missing the sum-certain demand is fatal to the claim, no matter how strong the merits. (Minors and incapacitated claimants get 180 days from when the disability ends.) There’s a quieter penalty too — no punitive damages against public entities (§ 12-820.04). If a government defendant is anywhere in your crash, the six-month window is your real statute of limitations, and building a credible sum-certain demand takes weeks of records work before it. Consult early or lose the defendant.

No caps — by constitutional command

Most states debate damage caps; Arizona’s founders banned them. The Arizona Constitution provides that “no law shall be enacted in this state limiting the amount of damages to be recovered for causing the death or injury of any person” (Art. 2, § 31), reinforced by the anti-abrogation clause (Art. 18, § 6). The result: no caps on economic or non-economic damages, in any injury case, ever — not even the medical-malpractice caps common elsewhere — and no statutory cap on punitive damages either (punitives are limited only by federal due-process review). Catastrophic cases in Arizona are therefore limited by exactly one thing: collectible coverage. The at-fault driver’s 25/50/15 minimum policy is gone before the first surgery is paid, so serious claims turn on the coverage hunt — commercial and employer policies, umbrellas, trucking defendants with federal minimums, dram-shop defendants, and your own UM/UIM.

The UM/UIM rule that changed — and most advice hasn’t

Arizona insurers must offer uninsured (UM) and underinsured (UIM) motorist coverage up to your liability limits, in writing, on a state-approved form (A.R.S. § 20-259.01). But here’s what pre-2015 articles get wrong: since Arizona’s 2015 reform, there is no signed “rejection form” fight — your declarations page is the final expression of what you bought or rejected. Two takeaways. First, check your declarations page now: with about 12% of Arizona drivers uninsured (IRC, 2022) — and one in three drivers nationally uninsured or underinsured — UM/UIM is the coverage that pays when a minimum-limits or no-insurance driver hits you. Second, in a dispute, what’s printed on that page is nearly conclusive, so policy-renewal paperwork isn’t junk mail in Arizona; it’s evidence.

Dram shop after Torres: statute or nothing

For forty years Arizona recognized both a statutory and a common-law claim against bars that overserved. In Torres v. JAI Dining Services (2023), the Arizona Supreme Court ended the common-law route — what survives is the statute, A.R.S. § 4-311: liability for a licensee that serves a customer who was “obviously intoxicated” (outward signs of significant impairment a reasonable person would notice) or a minor without checking ID, when that service proximately causes injury. Social hosts serving adults are immune (§ 4-301); serving minors is not protected. The evidence in these cases — bar receipts, POS records, surveillance video, toxicology math — evaporates in weeks, so a same-week preservation letter is standard practice. With alcohol involved in 27.9% of Arizona’s fatal crashes (ADOT 2024), this is not a footnote; it’s often the only solvent defendant behind an uninsured drunk driver.

What to do right now

If your crash was in the last few days: get every injury medically documented, get the crash report number, notify your own insurer (a policy duty), decline the at-fault insurer’s recorded statement, and photograph the vehicles before repair. Check whether any defendant might be public — that starts the 180-day clock — and pull your own declarations page to see your UM/UIM position. Then use the form on this page for a free case review with a vetted Arizona lawyer, or start with the car accident, motorcycle, or wrongful death guides. Arizona’s pure comparative rule means your case is probably worth pursuing even if you think the crash was partly your fault — that instinct to give up is the most expensive mistake this state’s law forgives.
