FOX 10 Phoenix reported that at least 12 people were hurt in a crash on Interstate 10 in Tucson, according to the Arizona Department of Public Safety. No further details were included in the report, and no determination of fault has been announced.
When a single collision injures a dozen people, the legal problem is rarely whether someone is liable; it is whether the available insurance can cover everyone. Arizona requires only modest minimum liability limits, and a multi-vehicle crash can produce more claims than one policy will pay. Insurers often resolve this by offering the policy limits to be divided among claimants, which rewards the people who document their injuries and present their claims early. Arizona also applies pure comparative fault under A.R.S. § 12-2505, so each driver's share of responsibility is assigned by percentage and a partially at-fault person still recovers a reduced amount. Underinsured motorist coverage on an injured person's own auto policy, and on some household policies, frequently becomes the largest source of recovery. Most injury claims must be filed within two years under A.R.S. § 12-542, and claims against a government entity require a written notice of claim within 180 days under A.R.S. § 12-821.01.
How Arizona Assigns Fault in a Multi-Vehicle Crash
Freeway pileups usually involve more than two vehicles and more than one theory of what happened. Arizona does not force a single answer. Under A.R.S. § 12-2505, a jury assigns a percentage of fault to every party whose conduct contributed, and your recovery is reduced by your own percentage. There is no cutoff; a person found 60 percent at fault still recovers 40 percent of their damages.
That matters because insurers in a mass-injury crash frequently argue that each injured person contributed something: following too closely, failing to slow, or changing lanes. Those arguments are negotiating positions, not findings. They are answered with evidence: the DPS report, vehicle damage patterns, event data recorder downloads, and statements from people who saw the sequence rather than only the aftermath.
If a driver is later cited or charged with anything, including impaired driving under A.R.S. § 28-1381 or leaving the scene under A.R.S. § 28-661, that is a separate criminal matter. A charge is not a conviction, and your civil claim proceeds on its own timeline and its own lower burden of proof.
When One Policy Cannot Cover Everyone
This is the practical reality of a crash with a dozen injured people. A liability policy has a per-person limit and a per-accident limit. Once the per-accident limit is exhausted, that policy is done, regardless of how many people are still untreated or unpaid. Steps that protect you:
- Identify every possible policy, not just the one obvious driver's. That can include other involved drivers, a vehicle owner who is not the driver, and an employer if any vehicle was being used for work.
- Check your own declarations page for uninsured and underinsured motorist coverage. In Arizona this coverage is commonly the difference between a token payment and a full recovery, and you may also be covered as a household member on a relative's policy.
- Check for medical payments coverage, which pays treatment bills without regard to fault and without waiting for the liability claim to resolve.
- Send written notice of your claim promptly. When limits are being divided, delay costs money.
What to Do in the First Weeks
Get evaluated even if you walked away. Injuries common in high-speed rear-end and chain-reaction impacts, including concussions and disc injuries, often present days later, and a gap in treatment becomes the insurer's main argument about causation.
Request the DPS report once it is available, and keep every bill, out-of-pocket receipt, and record of missed work. Photograph your vehicle before it is repaired or salvaged, because the vehicle itself is evidence and is often disposed of within weeks.
Give no recorded statement to another driver's insurer before you understand your own injuries. You are not required to provide one, and early statements made before a diagnosis are used later to minimize the claim. If a family member died, Arizona wrongful death claims are governed by A.R.S. § 12-611 to A.R.S. § 12-613, and claims that belonged to the person who died may survive under A.R.S. § 14-3110.
