ABC15 reported that a crash near Indian School Road and Interstate 17 closed southbound lanes on I-17 Wednesday night, according to the Arizona Department of Transportation. Southbound lanes have since reopened. No further details about those involved were reported.
A freeway crash that closes lanes often produces very little public information in the first days; media reports typically describe the closure, not who was hurt or why. That gap does not pause any legal deadline. In Arizona, a person injured by another driver's negligence generally has two years from the date of injury to file suit under A.R.S. § 12-542, and a claim against a public entity or public employee requires a written notice of claim served within 180 days under A.R.S. § 12-821.01. Fault is not all-or-nothing: A.R.S. § 12-2505 applies pure comparative fault, so damages are reduced by a claimant's own percentage of fault rather than barred. The practical first steps are to obtain the investigating agency's report number, preserve the vehicle and any dashcam or phone data, get medical evaluation documented, and give no recorded statement to another driver's insurer before understanding the injuries.
The Deadlines Run From the Date of the Crash, Not the Date You Learn What Happened
Waiting for an investigation to conclude is one of the most common ways people lose claims. The two-year period in A.R.S. § 12-542 starts running at injury, regardless of whether a report has been released or a citation issued. If a governmental entity or one of its employees is a potential defendant, the shorter clock in A.R.S. § 12-821.01 controls the first move: a written notice of claim, containing the facts supporting liability and a specific settlement amount, must be served within 180 days of when the claim accrues. Miss that, and the claim against that entity is barred even though the two-year period has not run.
If someone died, the claim structure changes. A wrongful death action under A.R.S. § 12-611 through A.R.S. § 12-613 belongs to a defined group of statutory beneficiaries, and it is separate from a survival action under A.R.S. § 14-3110 for what the decedent suffered before death. Determining who has the right to bring each one is worth sorting out early, because filing in the wrong capacity wastes time you may not have.
Get the Report, Then Get the Evidence That Nobody Else Is Preserving
Ask the investigating agency for the report number at the scene, or call the agency's records unit afterward with the date, location, and direction of travel. The report is useful, but it is not the whole case. An officer's opinion about fault does not bind an insurer or a jury, and reports on freeway collisions are sometimes revised.
What disappears fastest is everything else. Vehicles get repaired or sold for salvage, and the event data recorder inside goes with them. Nearby business and freeway camera footage is often overwritten within days or weeks. Tow yards charge daily storage and eventually dispose of vehicles. Photograph the damage from multiple angles before repair, keep the tow and storage receipts, and write down what you remember about traffic and road conditions while it is fresh. Then see a doctor and describe every symptom, not just the worst one; gaps in treatment are the argument insurers make most often.
Shared Fault and Multi-Vehicle Freeway Collisions
Chain-reaction crashes on interstates frequently involve more than two vehicles, and insurers respond by pointing at each other and at you. Arizona's pure comparative fault rule in A.R.S. § 12-2505 means a claimant assigned a share of fault still recovers, reduced by that percentage. Someone found ten percent at fault recovers ninety percent of proven damages. There is no threshold that cuts off recovery, so an early accusation of partial fault is a reason to document your side carefully, not a reason to walk away.
Separately, if a driver involved in a collision left without stopping and providing information, A.R.S. § 28-661 sets out the duty to stop and remain at the scene of a crash involving injury or death. That is a criminal statute, and any question of whether it was violated is for law enforcement and the courts; on the civil side, an unidentified driver usually shifts the focus to your own uninsured motorist coverage.
