Is Arizona a no-fault state? No.
Arizona operates a at-fault (tort) auto-insurance system under Ariz. Rev. Stat. § 28-4009. Minimum liability 25/50/15.
How Arizona\'s framework works in practice
Arizona has never adopted a no-fault auto-insurance system. Every Arizona-registered driver carries liability coverage in the statutory minimum amount of 25/50/15, and claims against that policy require proof of fault.
Without no-fault, Arizona claims move through traditional tort procedure: medical bills are pursued against the at-fault liability carrier, fault is contested, and comparative-negligence rules determine the final recovery. The system places more weight on the plaintiff's ability to document fault.
MedPay coverage in Arizona
Because Arizona does not require PIP, medical treatment after a crash is usually billed first to private health insurance, then either subrogated against the at-fault driver's liability coverage or held in a lien until settlement. The lack of mandatory PIP affects cash-flow timing for injured plaintiffs.
Minimum-liability coverage in Arizona
Minimum liability coverage required of every Arizona driver is 25/50/15 (Ariz. Rev. Stat. § 28-4009). That breaks down as per-person bodily-injury limit / per-accident bodily-injury limit / property-damage limit. The Arizona-minimum policy is the floor, not the ceiling , plaintiffs with serious injuries routinely exhaust the at-fault policy and pursue UM/UIM coverage or umbrella policies.
The Arizona claim process: from accident to recovery
The standard Arizona claim process treats the at-fault carrier as the first source of recovery. If that policy is inadequate, secondary sources include the plaintiff's own UM/UIM coverage, any applicable umbrella policies, and (in third-party-defendant cases) the assets of co-defendants. Each tier requires separate notice, separate documentation, and separate negotiation strategy. Missing a notice deadline on any tier can extinguish that source of recovery entirely.
Arizona auto-insurance carrier landscape
Arizona's auto-insurance market is dominated by a familiar set of carriers , State Farm, GEICO, Progressive, Allstate, Liberty Mutual, USAA, and Farmers , plus regional specialists. Arizona's Department of Insurance publishes complaint ratios and market-share data annually; carriers with high complaint ratios relative to market share are flagged for additional regulatory scrutiny. For plaintiffs, this matters because complaint-ratio data is admissible bias evidence in extreme bad-faith cases.
How Arizona's framework looks in real cases
Pattern: a Arizona pedestrian is struck in a crosswalk by a delivery van whose driver was looking at a phone. The defendant carries the minimum Arizona liability policy of $25,000. The plaintiff's UM/UIM coverage on their own policy is $300,000 stacked across three vehicles. The eventual recovery in such cases typically maxes out the defendant's liability and then taps the plaintiff's UIM for the balance, with a coordinated release between the two carriers to avoid coverage disputes.
Common mistakes that reduce Arizona case value
Plaintiffs in Arizona commonly underestimate the procedural complexity of personal-injury litigation. Common oversights include failing to identify all potential defendants (especially in commercial-vehicle cases where the driver, owner, and employer are often different entities), failing to preserve electronic evidence (text messages, GPS data, telematics), and failing to comply with policy-condition deadlines (e.g., examinations under oath for UM claims). Each oversight is recoverable if caught early but irreversible if caught late.
What this means for case value
In at-fault Arizona, your case value depends on (1) the at-fault driver's liability limits, (2) UM/UIM coverage on your own policy when those limits are inadequate, and (3) the comparative-fault rule that reduces recovery by your percentage of fault.
