12 News reported that the eastbound lanes of Grand Avenue in the West Valley are back open after a multi-vehicle crash closed them for a few hours. No further details about the crash have been released.
When three or more vehicles collide in Arizona, fault is rarely assigned to one driver and left there. Arizona uses pure comparative fault under A.R.S. § 12-2505, which means a jury assigns each party a percentage of responsibility and reduces that party's recovery by their own share. An injured person found twenty percent at fault still recovers eighty percent of their damages. In a chain collision, each insurer has an incentive to argue that someone else struck first, so the physical evidence, the vehicle positions, the police report, and any available video often decide the outcome rather than the drivers' accounts. Injured people should also know that more than one policy may be available; when the at-fault drivers carry minimum limits that several claimants must share, underinsured motorist coverage on the injured person's own policy frequently becomes the larger source of recovery. The deadline to file suit is generally two years under A.R.S. § 12-542.
Why Multi-Vehicle Crashes Are Fought Differently
In a two-car collision, the dispute is usually binary. In a pileup it is not. Three insurers can each accept a slice of responsibility, point at one another, and leave an injured person waiting while they argue. Nothing in Arizona law requires you to wait for them to agree.
A few practical consequences follow from A.R.S. § 12-2505:
- You can pursue more than one driver in the same claim. You do not have to pick the one you think is most responsible.
- Being partly at fault does not bar recovery in Arizona. It reduces it by your percentage, and nothing more.
- Each defendant is generally responsible for their own share, which is why identifying every involved vehicle early matters. A driver who is never identified is a share of fault nobody pays.
If any driver left the scene, A.R.S. § 28-661 sets out the duty to stop and remain after a crash involving injury or death. A departure does not establish anyone's civil liability on its own, but it is a fact worth preserving for investigators.
What to Do in the First Days
Evidence in a multi-vehicle crash disappears quickly. Vehicles get released to salvage yards. Businesses along a corridor overwrite surveillance video, sometimes within a week.
- Get examined, even if you walked away. Soft tissue injuries and head injuries commonly present a day or two later, and a gap between the crash and your first medical visit is the argument every adjuster makes.
- Request the police report number at the scene or from the investigating agency afterward. In a crash with several vehicles, that report is often the only document listing every driver and insurer.
- Photograph your own vehicle before it is repaired or totaled, including the interior and the pattern of damage. Impact sequence in a pileup is frequently reconstructed from crush patterns.
- Do not give a recorded statement to another driver's insurer before you understand your own injuries. You cannot accurately describe something you have not yet been diagnosed with.
- Pull your own auto policy and look for medical payments coverage and underinsured motorist coverage. Both are yours to use and neither depends on proving who caused the crash.
Deadlines That End Claims Quietly
Most Arizona injury claims must be filed within two years under A.R.S. § 12-542. Claims brought on behalf of someone who died are governed by the wrongful death statutes at A.R.S. § 12-611 through A.R.S. § 12-613, with claims that belonged to the decedent surviving under A.R.S. § 14-3110.
There is a much shorter deadline that catches people. If any public entity or public employee is a potential defendant, A.R.S. § 12-821.01 requires a written notice of claim served within 180 days of when the claim accrues. Miss it and the claim against that entity is barred, regardless of how strong it was. On a state route corridor with multiple vehicles involved, whether a public entity belongs in the case is not always obvious at first glance, which is a reason to evaluate it early rather than at the two-year mark.
