Arizona law sets a hard deadline of 2 years to file a car accident lawsuit. The controlling statute is A.R.S. § 12-542(1), and the clock generally starts on the date of the accident. Below: exactly when that clock starts, the exceptions that can pause it, and the traps that shorten it.

Arizona Deadlines for Related Claims

When the Clock Starts

In Arizona, the limitations period for car accident lawsuits generally begins on the date of the accident. Arizona recognizes a discovery rule for this claim type: Arizona's common-law discovery rule delays accrual until the plaintiff knows, or with reasonable diligence should know, the facts underlying the claim (Doe v. Roe, 955 P.2d 951 (Ariz. 1998)).

Exceptions That Can Extend the Deadline

The Arizona Constitution flatly prohibits any statutory cap on damages for personal injury or death (Ariz. Const. art. II, § 31), and minority tolls the two-year clock so it does not begin until the injured person turns 18 (A.R.S. § 12-502).

What to Do Before the Deadline Runs

  1. Pin down your accrual date — the day the clock started — and calendar the deadline conservatively.
  2. Preserve evidence now: photos, records, witness contacts, bills. Evidence decays faster than deadlines.
  3. Send preservation/notice letters where required (especially for Arizona government defendants).
  4. If the deadline is inside 6 months, treat it as urgent — filing suit is the only reliable way to stop the clock.

Frequently Asked Questions

How long do I have to file a car accident lawsuit in Arizona?

You have 2 years from the date of the accident, under A.R.S. § 12-542(1).

Can I still sue after 2 years in Arizona?

Usually no — courts dismiss claims filed after the statute of limitations expires. Narrow exceptions (the discovery rule, tolling for minors, fraudulent concealment) can extend the deadline; whether one applies depends on your facts.

Does the discovery rule apply to car accident lawsuits in Arizona?

Yes. Arizona's common-law discovery rule delays accrual until the plaintiff knows, or with reasonable diligence should know, the facts underlying the claim (Doe v. Roe, 955 P.2d 951 (Ariz. 1998)).

What if the victim was a minor?

Arizona generally pauses ("tolls") the deadline while the injured person is under 18, giving them time to file after reaching adulthood. Special limits can still apply, so check the statute.

Is the deadline different for claims against the government?

Before suing an Arizona public entity or public employee, a claimant must serve a notice of claim within 180 days after the cause of action accrues and then file suit within one year (A.R.S. §§ 12-821.01, 12-821).
