In Arizona, the arizona car accident statute of limitations and filing deadlines follow a strict two-year rule under A.R.S. 12-542. Victims of Car Accidents throughout the Phoenix metro have exactly two years from the date of their collision to file a civil lawsuit, or they permanently lose the right to recover any compensation.

The Two-Year Rule Under Arizona Law
Arizona Revised Statutes section 12-542 establishes the general deadline for personal injury claims at two years from the date of injury. For car accident cases, this means you must file lawsuit in civil court within two years of the date the collision occurred. This arizona statute limitations rule applies whether the other driver was distracted, impaired, or simply careless. It does not pause because you are still receiving medical care, still negotiating with insurance companies, or still waiting on a police report to come back.
Most injured people focus on recovery during those first weeks and months. Medical appointments, vehicle repairs, and lost time at work consume their attention. But the two-year clock is running from day one. Personal injury attorneys who handle arizona car accident cases see clients miss filing deadlines every year, and courts have no discretion to grant extensions based on hardship alone. When the window closes, it closes.
When the Clock Starts on Your Case
The statute begins on the date of the accident in almost every car accident case. If a crash happened on July 15, 2024, the deadline to file lawsuit is July 15, 2026. That is the baseline.
In some situations, the start date is less straightforward. Certain injuries do not produce clear symptoms immediately after a crash. A herniated disc or a traumatic brain injury may not be formally diagnosed until weeks or months later. Arizona courts recognize the discovery rule in limited circumstances: the statute of limitations begins when you knew, or reasonably should have known, of the injury and its connection to the accident. Courts apply this rule narrowly in car accident cases because the cause of injury is typically apparent at the scene. Do not assume a delayed diagnosis automatically extends your deadline. Consult an attorney early.
Exceptions That Can Shorten or Extend Your Deadline
Government Vehicles and the Notice of Claim Requirement
When the at-fault vehicle was owned or operated by a government entity, a shorter and separate deadline applies. Arizona Revised Statutes section 12-821.01 requires that you file a notice claim with the appropriate government entity within 180 days of the date the cause of action accrues. That is roughly six months, not two years.
The notice claim is a hard prerequisite. Injury claims against public entities that skip this step are dismissed regardless of the strength of the underlying case. Government vehicles include city buses, state fleet cars, county maintenance trucks, and public utility vehicles. If any government driver or vehicle was involved in your accident, treat your filing timeline as 180 days until an attorney confirms otherwise.
Minor Plaintiffs
If the injured person was under 18 at the time of the accident, Arizona law tolls, or pauses, the statute of limitations until the minor reaches 18. The two-year clock then starts on their 18th birthday. A parent or guardian may still bring injury claims on behalf of the minor before that point, and doing so promptly is often the right choice while evidence is still available.
Out-of-State Defendants
When the at-fault driver leaves Arizona after the accident and before a lawsuit is filed, the time they spend outside the state generally does not count toward the two-year statute. This provision protects plaintiffs who were hit by out-of-state drivers who returned home before suit could be filed.
Why Insurance Negotiations Do Not Stop the Clock
This misconception causes more missed deadlines than almost any other factor. Insurance companies often conduct negotiations that stretch over many months. Adjusters request additional medical records, schedule independent medical examinations, and send letters suggesting a resolution is near. None of that activity pauses the arizona statute limitations clock.
Insurance companies know your deadline. Some rely on extended negotiations precisely because a missed filing deadline eliminates their exposure entirely. You can still negotiate and accept a settlement right up to the deadline. But if no agreement is reached, you must file lawsuit before time runs out, or the case is gone.
If you are approaching the one-year mark without a signed agreement, consult an attorney as soon as possible. Filing a complaint does not mean your case will go to trial. Most personal injury cases settle after a lawsuit is filed, often within months. Filing preserves your rights while negotiations continue.
What Happens If You Miss the Filing Deadline
Filing after the statute of limitations expires ends your case immediately. The defense raises the expired deadline as an affirmative defense, the court grants dismissal, and your case is over. The severity of your injuries, the clarity of fault, and the quality of your evidence all become irrelevant at that point.
Courts grant very few exceptions. Equitable tolling, which can extend deadlines in cases of fraud or active concealment, requires clear proof that the defendant deliberately hid information needed to bring the claim. That standard almost never applies in standard car accidents.
Preserving Your Claim Before Time Runs Out
Knowing the arizona car accident statute of limitations and filing deadlines is only the first step. Acting early gives your case the strongest possible foundation. Evidence degrades quickly after a collision. Intersection surveillance footage is typically overwritten within days or weeks. Witnesses lose accuracy over time. Physical road evidence fades quickly: skid marks, debris, and damage to surrounding property disappear within days or weeks after car accidents.
Medical documentation that ties your injuries directly to the collision date is essential in Personal Injury cases throughout Arizona. Gaps in treatment create arguments that your injuries were not serious or were caused by something unrelated to the accident. Consistent care, documented thoroughly from the beginning, strengthens your claim for both economic damages including medical bills and lost wages, and non-economic damages such as pain, suffering, and loss of normal daily activity.
The at-fault driver’s insurance company has experienced claims adjusters and legal staff on your file from day one. You deserve the same level of preparation on your side.
Frequently Asked Questions
Does the two-year statute apply to uninsured motorist claims?
Yes. The two-year deadline applies to all arizona car accident civil claims, including uninsured motorist claims filed under your own policy. Some uninsured motorist policies contain separate contractual deadlines shorter than the statutory period. Read your policy language carefully and confirm with an attorney which deadline governs your specific situation.
What if the insurer has been promising a settlement for months?
Verbal assurances from an adjuster do not pause the statute of limitations. The clock runs on the calendar, not on the insurer’s promise of resolution. If two years are approaching without a signed agreement, you must file a lawsuit to preserve your claim. Settlement negotiations can continue after filing without affecting the case.
Does the filing date of the police report affect the deadline?
No. The statute of limitations in arizona car accident cases begins on the date the accident occurred, not the date a report was filed, the date you first sought medical treatment, or the date you hired an attorney. Only the collision date controls the baseline.
What is the deadline for a wrongful death claim in Arizona?
Arizona wrongful death claims under A.R.S. 12-542 carry a two-year deadline running from the date of death, which may differ from the date of the accident if the victim survived for a period following the crash. The personal representative of the estate or eligible family members must file within that window.
Can a child injured in a car accident sue after turning 18?
Yes. Arizona law tolls the statute of limitations for minors. If a child was hurt in a car accident, the two-year clock begins on their 18th birthday, giving them until age 20 to file independently. Earlier legal action by a parent or guardian is possible and often advisable while evidence remains accessible.
