After a crash, the last thing on your mind is a legal deadline. You are focused on getting better, fixing your car, and paying the bills that keep arriving. That is completely understandable.
But Arizona law puts a clock on your right to compensation. Miss the deadline, and even a rock-solid case is worth nothing. This page explains exactly how much time you have, the traps that shorten it, and why waiting hurts you long before the deadline arrives.
The short version: you generally have two years, but some claims must be started in as little as 180 days. Here is how it all works.
The General Rule: Two Years From the Date of the Crash
Under A.R.S. § 12-542, you have two years from the date of the crash to file a lawsuit for injuries caused by someone else’s negligence. The same two-year deadline applies to property damage claims, such as the cost of repairing or replacing your vehicle.
This deadline is called the statute of limitations. It is not a soft target. If you file even one day late, the defendant can ask the court to dismiss your case, and the court will almost always agree. The strength of your evidence will not matter. The severity of your injuries will not matter.
Statutes of limitations vary by state, often two or three years, so do not rely on what a friend in another state experienced. In Arizona, the number to remember is two years.
What the Two-Year Deadline Covers
The two-year clock applies to the core claims that come out of most crashes:
- Personal injury claims for medical bills, lost wages, and pain and suffering
- Property damage claims for your vehicle and other damaged belongings
Both clocks generally start on the date of the crash. If your crash happened on a specific date, mark two years from that date on your calendar now, and plan to act long before it.
Wrongful Death: Two Years From the Date of Death
When a crash takes a life, the family may bring a wrongful death claim. In Arizona, that claim must be filed within two years of the date of death, not the date of the crash.
For many families those dates are the same. But when a loved one survives for a time after the crash and later passes away from their injuries, the wrongful death clock starts on the date of death. Families dealing with this kind of loss should speak with an attorney early so the deadline is calculated correctly for their situation.

Claims Against the Government: 180 Days, Then One Year
Here is the trap that catches the most people. If your claim is against a city, county, or the State of Arizona, the two-year rule does not protect you. Under A.R.S. § 12-821.01, you must:
- File a formal Notice of Claim within 180 days. This is a specific legal document with required contents, not just a phone call or an email to the city.
- File any lawsuit within one year.
Government claims come up more often than people expect. A crash with a city vehicle, a police cruiser, a county truck, or a public bus can all trigger these rules. So can a crash caused by a dangerous road condition, like a broken traffic signal or a poorly designed intersection maintained by a public entity.
One hundred eighty days is about six months. That window can close while you are still in physical therapy. If there is any chance a government entity played a role in your crash, get legal help immediately.
Can the Deadline Ever Be Extended?
In some situations, Arizona law pauses, or “tolls,” the statute of limitations. Two general concepts come up most often:
- Minors. When the injured person is a child, the law generally gives them additional time, because a minor cannot file a lawsuit on their own.
- Discovery. In limited situations, the clock may not start until the injured person knew, or reasonably should have known, about the injury and its cause.
These rules are narrow, fact-specific, and frequently disputed. Never assume an exception applies to you. The only safe approach is to treat the standard deadline as firm and let an attorney evaluate whether any exception genuinely fits your case.
Why Waiting Hurts You Long Before the Deadline
Two years sounds generous. In reality, the value of your case starts eroding within days of the crash. Here is why acting early matters:
- Evidence disappears. Skid marks fade, vehicles get repaired or scrapped, and intersection camera footage is often overwritten quickly.
- Witnesses scatter. People move, change phone numbers, and forget details. A witness statement taken in week one is far more useful than one chased down in year two.
- Gaps in treatment get used against you. If you delay seeing a doctor, the insurance company will argue you were not really hurt, or that something else caused your injuries.
- Lawsuits take preparation. A lawyer needs time to gather records, consult experts, and try to settle before filing. Walking into a law office two weeks before the deadline leaves little room to build a strong case, and some attorneys may decline a case that close to the cutoff.
The people who recover the most are usually the ones who started the earliest. Early action also matters under Arizona’s comparative negligence rules, because fresh evidence is your best defense against the insurer inflating your share of fault.
Insurance Policy Deadlines Are a Separate Problem
The statute of limitations controls when you can file a lawsuit. Your insurance policy has its own, separate deadlines, and they are usually much shorter.
Most policies require “prompt notice” of a crash and cooperation with the insurer’s investigation. If you wait months to report the accident, the insurance company may argue you violated the policy and try to deny coverage, even though the two-year lawsuit deadline is nowhere close.
This applies to your own insurer too, especially for uninsured and underinsured motorist claims. The safest practice is simple: report the crash to your insurer promptly, keep your statements brief and factual, and talk to a lawyer before giving any recorded statement.
Frequently Asked Questions
How long do I have to file a car accident lawsuit in Arizona?
Generally two years from the date of the crash, for both personal injury and property damage claims, under A.R.S. § 12-542.
What if my crash involved a city or state vehicle?
Much shorter deadlines apply. You must file a formal Notice of Claim within 180 days and any lawsuit within one year under A.R.S. § 12-821.01.
Does the two-year deadline apply to insurance claims too?
No. Insurance policies have their own “prompt notice” requirements, which are separate from the statute of limitations and usually much shorter. Report your crash to your insurer promptly.
What happens if I miss the deadline?
The at-fault party can ask the court to dismiss your lawsuit, and courts almost always grant that request. In most cases, missing the deadline ends your right to compensation, which is why early legal advice is so important.
