Arizona Personal Injury Law

What Is Personal Injury Law in Arizona?

Personal injury law in Arizona covers cases where a person is harmed due to someone else's negligence or intentional conduct. Arizona follows a pure comparative negligence system under A.R.S. § 12-2505, meaning your compensation is reduced by your percentage of fault — but you can still recover even if you're 99% at fault. This is more favorable to plaintiffs than many other states. Common personal injury cases in Arizona include motor vehicle accidents (Phoenix has one of the highest traffic fatality rates in the nation), premises liability, product liability, and medical malpractice.

When Do You Need a Personal Injury Attorney?

Consult a personal injury attorney if you've been injured in a car accident, slip and fall, workplace incident, or any situation caused by another party's negligence. Arizona has a two-year statute of limitations (A.R.S. § 12-542) for most personal injury claims. For claims against government entities, you must file a notice of claim within 180 days.

Arizona Personal Injury Sub-Specialties

Personal injury law covers many case types in Arizona, each with its own statutory framework and procedural quirks. Below are the most common sub-specialties — with the Arizona-specific rules that distinguish them.

🚗 Auto Accidents

Auto accidents are the most common personal injury claim in Arizona. Pure comparative negligence (ARS § 12-2505) lets you recover even if you're 99% at fault — your award is just reduced by your percentage of fault. The state minimum auto liability is 25/50/15 ($25K bodily injury per person / $50K per accident / $15K property damage) under ARS § 28-4009 — often inadequate for serious injury, making UM/UIM coverage (ARS § 20-259.01) one of the highest-ROI policies a driver can carry. The 2-year statute of limitations (ARS § 12-542) runs from the date of the crash, with a discovery-rule extension for injuries not immediately apparent. Phoenix consistently ranks among the top US metros for traffic fatalities and pedestrian deaths.

🏥 Medical Malpractice

Arizona medical malpractice has a procedural hurdle most plaintiffs don't anticipate: ARS § 12-2603 requires a preliminary expert affidavit within 30 days of the defendant's answer, certifying the case has merit. The standard of care is what a reasonably prudent provider in the same specialty would do under similar circumstances — not perfection. Hospitals are typically liable vicariously for employed physician negligence, though many ER doctors and specialists are independent contractors, complicating liability. Arizona does not cap malpractice damages (Arizona Constitution Article 2 § 31). The 2-year statute of limitations (ARS § 12-542) applies, with a discovery-rule extension when injury isn't immediately apparent (e.g., retained surgical instrument discovered years later). Common claims: birth injuries, surgical errors, missed cancer diagnoses, medication errors. Informed-consent claims require proof the patient would have refused had they known the material risk.

🕊 Wrongful Death

Arizona's wrongful death statute is ARS §§ 12-611 to 12-613. Only a statutory beneficiary can sue: the surviving spouse, surviving children (regardless of age), surviving parents, OR the personal representative of the decedent's estate on behalf of these beneficiaries. Recoverable damages include funeral and burial expenses, lost financial support, AND loss of companionship, comfort, and guidance — Arizona is among the more generous states for non-economic damages in wrongful death. The 2-year statute of limitations runs from the date of death, not the date of the underlying injury. A separate survival action can be brought by the estate for pre-death medical expenses and pain and suffering. Both claims often run in parallel. Claims against government employees still require the 180-day notice of claim under ARS § 12-821.01.

🚧 Slip & Fall / Premises Liability

Premises liability turns on the entrant's legal status. Invitees (business customers) get the highest duty — proprietors must inspect for hazards and warn or remedy dangerous conditions. Licensees (social guests) get a lower duty — warn of known hazards. Trespassers receive only a duty to avoid willful or wanton harm (with exceptions for attractive nuisance involving children). Common Arizona cases: grocery store slips on transitory hazards (spilled liquids), parking lot trip-and-falls (uneven pavement), hotel/resort pool incidents, and apartment-complex security failures. Plaintiffs typically need to show the landowner knew or should have known about the hazard with enough time to remedy or warn. Comparative fault often weighs heavily — was the customer texting while walking, ignoring warning signs. Arizona's 2-year statute of limitations (ARS § 12-542) applies.

🐕 Dog Bites

Arizona is a strict liability state for dog bites under ARS § 11-1025 — the owner is liable from the first bite, with no "one free bite" defense common in many other states. The plaintiff must show: (1) the defendant owned the dog, and (2) the bite occurred while the plaintiff was lawfully on public or private property. Arizona has a special 1-year statute of limitations for strict-liability dog-bite claims (ARS § 12-541) — shorter than the 2-year general PI window. Miss it and you lose strict liability, though common-law negligence remains for 2 years. Exceptions: trespassers can't recover, and provocation is a defense. Lawful presence covers postal workers, utility workers, and invited social guests. Homeowner's insurance typically covers dog-bite liability, making collection less of an issue than in other PI cases.

🧠 Brain Injury / TBI

Traumatic brain injuries (TBI) are among the highest-value personal injury cases because of lifetime impact. Mild TBI (concussion) often resolves but can persist as post-concussive syndrome with cognitive deficits, mood changes, and chronic headaches — frequently challenged by defense as malingering. Moderate-to-severe TBI requires life-care planning: home modifications, ongoing therapy, vocational retraining, and 24-hour care in catastrophic cases. Documentation matters enormously: neuropsychological testing, day-in-the-life videos, vocational economist reports establishing diminished earning capacity. Structured settlements (annuity-funded periodic payments) are common to preserve the tax-free status of personal injury damages while ensuring funds last. Arizona has no damage caps. The 2-year statute of limitations applies, with the discovery rule extending start when symptoms emerge weeks or months later — common for sports-related TBI.

🏍 Motorcycle Accidents

Arizona has no helmet law for riders 18 and older (ARS § 28-964 covers riders under 18 only), making head injuries disproportionately severe. UM/UIM coverage on a motorcycle policy is often the difference between full recovery and catastrophic financial loss given the size of medical bills. Lane splitting and lane sharing remain illegal in Arizona (unlike California), so riders weaving between cars face fault even when struck. Jurors often carry bias against motorcyclists — case presentation matters: helmet use, license/endorsement compliance, sober riding, and reasonable speed all build credibility. Common collision factors: left-turn-in-front-of-rider (most common type), road-debris incidents on rural highways, dangerous lane changes by inattentive drivers. The 2-year statute of limitations applies. Many riders carry rider-specific UIM in addition to standard auto policies.

🚛 Truck Accidents

Commercial truck accidents involve federal regulations — the Federal Motor Carrier Safety Regulations (FMCSR) — in addition to Arizona state law. Commercial insurance minimums are far higher than passenger auto (typically $750K to $5M for general freight, $5M for hazardous materials), reflecting the catastrophic damage potential of a fully loaded 80,000-pound vehicle. Multiple defendants typically share liability: the driver, the trucking company (respondeat superior), and sometimes the truck manufacturer, the cargo loader, or the maintenance shop. Discovery focuses on Hours-of-Service (HOS) logs (now electronic via ELDs), driver qualification files, drug/alcohol testing records, and maintenance histories. CDL standards and the carrier's safety rating are often litigated. Spoliation letters preserving electronic data should go out immediately — telematics data is frequently auto-purged after 30-90 days.

Costs and Timeline

Most personal injury attorneys in Arizona work on a contingency fee basis, typically 33-40% of the settlement or verdict. You pay nothing upfront and nothing if you don't recover.

Arizona Laws and Statutes

Key Arizona statutes: A.R.S. § 12-542 (2-year statute of limitations), A.R.S. § 12-2505 (comparative negligence), A.R.S. § 12-711 (wrongful death). Arizona does not cap compensatory damages in most cases.
