Car accident in Tucson, AZ? What your claim involves
A crash in Tucson is governed by Arizona law and, if it goes to court, heard in Pima County. Here is what that means for your deadline, your fault share, and the insurance that pays.

Where a Tucson crash claim is decided
Tucson is in Pima County, and a lawsuit over a crash in the city is ordinarily filed in the Pima County Superior Court. Most claims never get that far — they settle with the at-fault driver’s insurer — but the court, its local juries and its caseload are part of what an insurer weighs when it decides what to offer.
Freeway or city street: who answers for the road
I-10, I-19 are part of the state highway system maintained by ADOT. If road design, a missing sign, debris or a work zone contributed to a crash there, the claim is against the state. A crash caused by a defect on a city street such as Speedway Boulevard, Grant Road, Oracle Road is a claim against the City of Tucson.
Either way it is a government claim, and a notice of claim must be served on the public entity within 180 days, and any lawsuit must be filed within one year of the crash. Most crashes, though, are about another driver, and those claims run on the ordinary 2-year deadline.

How fault is split in Tucson
Arizona uses pure comparative fault: your recovery is reduced by your share of the blame, but you are not barred from recovering even if you were mostly at fault.

The insurance that pays
Arizona requires $25,000 per person in liability coverage — the most a minimum policy pays for one injured person. When a Tucson crash causes injuries that cost more, your own coverage matters. Insurers must offer uninsured and underinsured motorist coverage in writing; a policyholder can reject it.

Right after a crash in Tucson
Call 911 if anyone is hurt; on I-10 and other state highways the Arizona Department of Public Safety usually responds, while crashes on city streets are handled by local police. A driver in a crash causing injury or death must stop, give their information, and render reasonable assistance, and the crash must be reported to police.
Photograph the scene, get the other driver’s insurance, collect witness contacts, and see a doctor within a day even if you feel fine.
