The 2-Year Clock: Phoenix Car Accident Claims Explained

Two years sounds like plenty of time, which is exactly why the deadline catches people. The two-year rule is the general rule, not the only one and several Arizona claims arising from the same crash run on much shorter clocks. Some expire in one year. One expires in 180 days. And a few are governed by your insurance policy rather than any statute.

What Is the Deadline for a Phoenix Car Accident Claim?

Two years, in most cases. Under A.R.S. § 12-542, an action for personal injury must generally be brought within two years after the cause of action accrues. The same two-year period applies to property damage from the collision, including a diminished value claim for the market value of your repaired vehicle permanently lost.

One distinction matters in fatal cases. A wrongful death action runs two years from the date of death, not the date of the collision. Where someone survives an initial hospitalization and dies weeks later, those are different dates.

Filing means starting a lawsuit in court. Reporting the crash to an insurer, opening a claim, or exchanging demand letters does not satisfy the deadline.

When Does the Clock Actually Start?

Usually the date of the crash but not always. Arizona follows the discovery rule: a cause of action occurs when the injured person knows, or with reasonable diligence should know, the facts underlying the claim.

That matters in two recurring situations. First, where an injury was missed or misattributed early. A closed head injury dismissed as stress at the emergency department, or a disc injury that surfaces weeks later, may involve an accrual question see delayed injuries after a crash. Second, where the responsible party was not initially identifiable.

The discovery rule is a genuine principle, not a safety net. Courts apply it to facts a claimant could not reasonably have known, and relying on it as extra time is a poor plan.

Which Deadlines Are Shorter Than Two Years?

Several, and this is the part almost nobody is told. A single Phoenix crash can generate claims running on four different clocks at once:

The workers’ compensation overlap deserves emphasis, because it is invisible to most people. If you were driving for work and are receiving compensation benefits, A.R.S. § 23-1023 gives you one year to institute the third-party action against the at-fault driver. Miss it, and the claim is deemed assigned to the compensation carrier, which may then prosecute it, settle it, or reassign it on its schedule, not yours. See how the two claims run on separate tracks.

The uninsured motorist deadline is contractual rather than statutory. Many policies condition coverage on prompt reporting to law enforcement commonly within 24 hours and on prompt written notice to the insurer. Missing a policy condition can end the claim while the two-year statutory period is still wide open, and it is the most common way a viable recovery is lost. See how uninsured motorist coverage works.

One period is genuinely unsettled. Where a liquor licensee over-served the driver, the dram shop limitations period is unclear after the Arizona Supreme Court’s decision in Torres v. JAI Dining Services removed the common-law claim. A.R.S. § 4-312 is a liability limitation rather than a limitations statute, and the strongest argument is that the one-year period in A.R.S. § 12-541 now applies because dram shop liability exists only by statute though an older court of appeals decision applied two years. The prudent course is to treat one year as the deadline. Note also that A.R.S. § 4-302 requires filing a copy of a dram shop complaint with the Arizona Department of Liquor Licenses and Control within 10 days. See Arizona dram shop liability.

What If a City Bus or Government Vehicle Was Involved?

Then the real deadline is 180 days, not two years. Under A.R.S. § 12-821.01, a claim against a public entity or public employee must be served within 180 days after the cause of action accrues, on the person authorized to accept service for that entity. The notice must state facts sufficient to permit the entity to understand the basis of liability, and must include a specific amount for which the claim can be settled together with the facts supporting that amount.

Three further points:

• A claim not accepted within 60 days is deemed denied.
• Suit must then be filed within one year of accrual under A.R.S. § 12-821 not two.
• Serving the wrong office can bar the claim. Some entities do not accept service at the location where the incident happened. A public university, for example, is governed by a statewide board that handles service separately from the campus itself.

This reaches more situations than people expect: a city vehicle, a transit bus, light rail, a signal timing failure, or a dangerous roadway condition. Families dealing with a hospitalization rarely learn about it in time.

What If the Injured Person Is a Child?

The clock generally does not run while they are a minor. A.R.S. § 12-502 provides that where a person entitled to bring an action is under eighteen when the cause of action accrues, the period of that disability is not counted, and they have the same time after turning eighteen that anyone else would have.

Two cautions. A.R.S. § 12-503 prohibits tacking successive disabilities together. And tolling for a minor does not rescue a parent’s own claim; a parent seeking their own damages, or medical expenses they paid, is generally on the ordinary schedule. For public entity claims, § 12-821.01 contains its own provision for minors rather than deferring to the general rule.

Does Anything Pause the Clock?

Not the things people assume. Settlement negotiations do not toll the deadline. Neither does an adjuster saying the file is still open, a pending repair, ongoing medical treatment, or an insurer’s internal claims process. A carrier has no obligation to warn you that your deadline is approaching, and none of them do.

If the period expires, the claim is generally barred regardless of how strong the liability picture was or how serious the injuries are. Courts extend these deadlines only in narrow circumstances.

Frequently Asked Questions

How long do I have to file a car accident lawsuit in Arizona? Generally two years from the date of injury under A.R.S. § 12-542. A wrongful death action runs two years from the date of death rather than the date of the crash. Filing means starting a lawsuit in court reporting the claim to an insurer does not satisfy the deadline.

Does the two-year deadline apply if a government vehicle hit me? No. A claim against a city, county, or state entity generally requires a formal notice of claim served within 180 days under A.R.S. § 12-821.01, on the official authorized to accept service, with a specific settlement amount and supporting facts. Suit must then be filed within one year under A.R.S. § 12-821.

What if my child was hurt in the crash? A minor’s claim is generally tolled until age eighteen under A.R.S. § 12-502, so they have the standard period after turning eighteen. That protection does not extend to a parent’s own claim for their damages or for medical expenses they paid, which typically runs on the ordinary two-year schedule.

Can the deadline start later than the crash date? Sometimes. Arizona applies the discovery rule, under which a claim accrues when the injured person knows, or with reasonable diligence should know, the facts underlying it. That can matter where an injury was missed at the emergency department or the responsible party was not identifiable but it applies to what could not reasonably have been known, not to delay.

Do settlement talks with the insurance company extend my deadline? No. Negotiations, an open claim file, ongoing treatment, and an adjuster’s assurances toll nothing. Insurers have no duty to notify you that the period is running out.

I was driving for work. Is my deadline different? It can be much shorter. If you are receiving workers’ compensation, A.R.S. § 23-1023 generally gives you one year to bring the third-party claim against the at-fault driver, after which it is deemed assigned to the compensation carrier. That is half the general deadline, and it surprises injured workers regularly.

Why Acting Early Matters More Than the Deadline

The filing deadline is the last date the courthouse will accept your case. It is not the date your case stops being winnable that happens much sooner and much more quietly.

Camera footage from businesses and doorbell systems commonly overwrites within days. Vehicle event data recorders leave with the car when it goes to salvage. Witness contact details go stale. Phone and app records are retained for limited periods. A crash report with a reversed direction of travel is easy to correct in week one and very hard in month eighteen.

Because evidence and witness memory fade quickly, reaching out to a Phoenix car accident lawyer well before the deadline gives your case its best chance.
