12 News reported that southbound Interstate 17 was closed near Indian School Road because of a crash, according to authorities. That is the extent of what has been made public. No cause has been announced, no one has been found responsible, and the number of people hurt has not been released. If you were involved, or you are trying to find out whether a family member was, the information gap in the first hours is normal; it is also the period when the decisions that shape a claim get made.
Freeway collisions in Arizona raise a fault question that surface street crashes usually do not: when traffic is moving at speed and several vehicles are involved, more than one driver may share responsibility, and the insurers involved will each argue the other side carries most of it. Arizona uses pure comparative fault under A.R.S. § 12-2505, which means an injured person can recover even if partly at fault; the award is reduced by that person's percentage of responsibility, and there is no cutoff at which recovery disappears. Being assigned some blame in a police report, or by an adjuster on a recorded call, does not end a claim. The deadline to file suit against a private driver is two years under A.R.S. § 12-542. If a government vehicle or a public entity is involved, a written notice of claim is due within 180 days under A.R.S. § 12-821.01, which is far shorter than most people expect.
Partial Blame Is Not a Bar to Recovery
Adjusters handling freeway crashes often open with a theory that the injured person was following too closely, changing lanes, or driving too fast for conditions. Under A.R.S. § 12-2505, even if a jury agreed in part, that finding reduces the recovery by a percentage rather than eliminating it. A person found 30 percent responsible for a $100,000 loss recovers $70,000. This matters in practice because early fault percentages are usually guesses made before anyone has read the full investigative report, downloaded vehicle event data, or spoken to the people who were behind and beside the vehicles involved.
Two related points. First, the responding agency's initial narrative is evidence, not a verdict; it can be contradicted. Second, if a driver left the scene, Arizona law imposes a separate duty to stop and provide information under A.R.S. § 28-661, and an unidentified driver does not necessarily mean no coverage; uninsured motorist coverage on your own policy may apply.
The Deadlines That Actually Control Your Case
Most injury claims from a car crash must be filed in court within two years under A.R.S. § 12-542. If someone died, the wrongful death claim belongs to the statutory beneficiaries described in A.R.S. § 12-611 through A.R.S. § 12-613, and claims the deceased person held personally may survive under A.R.S. § 14-3110.
The deadline people miss is the government one. If a public entity or public employee may bear responsibility, whether because of a government vehicle, a road maintenance issue, or a public works operation, a written notice of claim must be served within 180 days of when the claim accrues under A.R.S. § 12-821.01. That notice must state a specific settlement amount and the facts supporting it. Miss it and the claim against that entity is generally gone, regardless of how much time remains on the two-year clock.
Practical Steps in the First Two Weeks
Get evaluated even if you walked away. Adrenaline masks injury, and a gap between the crash date and the first medical visit is the most common argument insurers use to discount a claim.
Request the crash report from the investigating agency once it is available, and write down what you remember today: lane position, what you saw ahead, what you heard, who stopped to help. Photograph your vehicle before it is repaired or sold for salvage, including the interior. Freeway crashes are sometimes captured by traffic cameras and by dashcams in surrounding vehicles, and that footage is often overwritten within weeks, so a written preservation request sent early is worth more than the same request sent later.
Report the crash to your own insurer, which your policy requires, but decline to give a recorded statement to any other driver's insurer until you understand your injuries. You are not obligated to speculate about speed, distance, or fault.
