Car accident statutes of limitations: how long you actually have to file

In 2024, police responded to an estimated 6.18 million motor vehicle traffic crashes in the United States, and roughly 2.4 million people were hurt in them.¹ Every one of those people started a legal clock the moment the collision happened, whether they knew it or not. That clock is the statute of limitations, and it's the single deadline that matters most in a car accident claim. It outranks the property damage estimate, the adjuster's phone calls, even the medical bills. Miss it, and the strongest case in the country becomes worthless in a courtroom.

This page covers how that deadline works nationally: what starts it, what pauses it, what shortens it, and what can wipe it out early depending on who or what you're suing. The exact number of years is set state by state, and it varies enough, from one year to six, that you should confirm the figure for your own state before making any decision based on a calendar. But the mechanics behind the number work largely the same everywhere, and that's what this guide is for.

What a statute of limitations actually does

A statute of limitations is a law that caps how long an injured person has to file a lawsuit. It isn't a courtesy or a soft target insurers use to nudge you toward a quick settlement, though plenty of adjusters will let you believe that. It's a jurisdictional deadline. Once it passes, the defendant can ask the court to dismiss the case on that basis alone, and courts generally have to grant that request no matter how clear the negligence was or how serious the injuries are. There's no judge who can simply decide the delay was reasonable and let a plainly late case proceed.

The purpose isn't to punish injured people. It exists because evidence degrades, memories fade, and vehicles get repaired or scrapped. Legislatures decided that at some point, a defendant's interest in defending a claim with reliable evidence has to outweigh a plaintiff's interest in unlimited time to sue.

How long you actually have

Most states give an injured person somewhere between one and three years to file a personal injury lawsuit arising from a car accident, with two years being the single most common figure. California, for example, sets a two-year deadline for personal injury and wrongful death claims caused by negligence.² A handful of states run considerably longer. Maine's general civil statute of limitations is six years, and it covers most car accident injury claims that don't fall under a more specific statute.³

At the short end, Kentucky and Tennessee are usually cited as the strictest, with general one-year deadlines for personal injury.⁴ Kentucky is a good illustration of why you can't rely on the general personal injury rule for a car accident specifically. KRS 413.140 sets a one-year deadline for injury claims generally,⁵ but Kentucky's Motor Vehicle Reparations Act carves out its own rule for accidents involving a vehicle, running two years from the date of injury or from the date of the last no-fault benefit payment, whichever is later.⁶ A state's auto-specific statute can override its general personal injury statute, and you have to check which one actually applies before calculating a deadline off a generic chart.

The deadlines also move over time. Louisiana replaced its one-year prescriptive period for most tort claims with a two-year period under Act 423, but only for injuries that occurred on or after July 1, 2024.⁷ Anything before that date is still governed by the old one-year rule. A state's deadline this year is not necessarily the same one that applied when an older crash happened, which is one more reason not to rely on secondhand advice.

Property damage claims from the same crash don't always share the injury deadline, either. Some states run one clock for bodily injury and a longer one for damage to your vehicle, so a single collision can carry two separate expiration dates depending on what you're claiming.

When the clock starts running

In the overwhelming majority of car accident cases, the clock starts on the date of the crash. That's true even if you don't yet know the full extent of your injuries. You don't get to wait until you've finished treatment to start the countdown.

The exception is the discovery rule, which delays accrual until an injury or its cause wasn't reasonably knowable at the time of the incident. The U.S. Supreme Court laid out the modern framework for this in United States v. Kubrick, holding that a claim accrues once a plaintiff knows of both the injury and its cause, not once the plaintiff realizes that what caused it might have been negligent.⁸ That standard, developed in a case about a veteran's delayed-onset hearing loss, is the same logic courts apply nationally when a car accident victim discovers a real, hidden problem well after the wreck. It's a narrow exception. Knowing you were in a crash and later learning your injuries turned out worse than expected doesn't reopen the clock. Not knowing you had an injury at all, or not knowing what caused it, can.

Tolling: when the countdown pauses

Several categories of plaintiffs and defendants get the clock paused, or tolled, for periods that don't count against the deadline. The most common is age. If the injured person was a minor when the crash happened, most states pause the clock until they turn eighteen, then start or restart the countdown from there. California's tolling statute works this way, excluding the period of minority from the limitations calculation entirely.⁹ The same logic often applies to plaintiffs who are mentally incapacitated at the time of the crash.

Tolling can also work against the person you're suing. In California, if a defendant leaves the state after the cause of action accrues, the time they spend outside the state doesn't count toward the limitations period, which can extend a plaintiff's real deadline well past the nominal one on paper.¹⁰ Rules like these vary in scope from state to state, but the underlying idea, pausing the clock instead of running it against someone who can't reasonably be expected to act, shows up almost everywhere.

Wrongful death runs on its own clock

If a crash victim dies from their injuries, the surviving family's wrongful death claim is often a legally distinct action from the injury claim the victim could have brought, and it frequently runs on its own timeline measured from the date of death rather than the date of the crash. Illinois's Wrongful Death Act sets a standard two-year deadline from the date of death, with a separate, longer window, up to five years, or one year after the criminal case concludes, when the death resulted from certain violent or intentional conduct tied to homicide charges.¹¹ Not every state structures it this way. Some fold wrongful death into the same general personal injury statute that covers the underlying negligence claim, so the death claim and the injury claim share a single clock instead of running two separate ones. Which structure your state uses changes both when the deadline starts and how much time a grieving family actually has.

It's also worth separating the civil deadline from any criminal case. A drunk or reckless driver being prosecuted for vehicular homicide doesn't pause or extend the ordinary civil statute of limitations in most states. The criminal and civil tracks run independently, with Illinois's homicide-linked extension being a notable exception rather than the rule.

Government vehicles run on a shorter, different clock

If the vehicle that hit you was owned by a city, county, state agency, or the federal government, the standard statute of limitations you'd expect for a private driver usually doesn't apply at all. Suing a public entity requires clearing a much shorter administrative notice deadline first. California requires a claim for personal injury or property damage against a public entity to be presented within six months of accrual, long before the two-year lawsuit deadline that would apply to a private driver in the same crash.¹²

Federal vehicles work through the Federal Tort Claims Act, which requires a written administrative claim, typically Standard Form 95, presented to the responsible agency within two years of the accident.¹³ You can't skip straight to court. The FTCA specifically bars a lawsuit until the agency has first received and acted on that administrative claim.¹⁴ If the agency denies it, you then have six months from the denial to file suit. Miss the two-year administrative deadline, or the six-month suit deadline after denial, and the claim is generally gone for good, regardless of how strong it is. These government deadlines are jurisdictional in a way the ordinary civil statute of limitations sometimes isn't, so courts have very little room to forgive a late filing.

No-fault and PIP claims move on a much faster clock

Separate from the multi-year window to file a lawsuit, most no-fault and PIP systems impose their own short notice deadline for getting your own insurer to pay first-party medical and wage-loss benefits. New York requires written notice of a no-fault claim within 30 days of the accident, and once you've supplied proof of the loss, the insurer's payment is considered overdue if it isn't made within 30 days after that.¹⁵ None of that has anything to do with the years-long deadline to sue anyone. It's a contractual and regulatory claims-filing deadline that runs on its own, much shorter, calendar, and missing it can cost you no-fault benefits you'd otherwise have been entitled to, even while your lawsuit deadline is still years away. Report a crash to your own insurer immediately regardless of how much time you think you have to sue anyone else.

Crossing state lines complicates the deadline

A crash that happens in one state, involving a driver from a second state, followed by a lawsuit filed in a third, raises a real question about whose statute of limitations controls. Courts have long treated statutes of limitations as procedural rather than substantive for choice-of-law purposes, which generally lets the state where the lawsuit is actually filed apply its own limitations period, even to a claim otherwise governed by another state's substantive law. The U.S. Supreme Court upheld this approach against a constitutional challenge in Sun Oil Co. v. Wortman, rejecting the argument that a forum state violates the Full Faith and Credit Clause by applying its own statute of limitations to an out-of-state claim.¹⁶ In practice, that means the deadline that matters most is usually tied to where you file suit, not simply where the crash happened or where you live, and the two aren't automatically the same. Anyone dealing with an out-of-state crash should confirm which state's clock actually governs before assuming their home state's number applies.

A defective vehicle puts you on a second, harder deadline

If a defect caused or worsened the crash, a product liability claim against the manufacturer runs alongside, not instead of, the ordinary negligence claim against the other driver, and it comes with its own limitations rules. Many states also impose a statute of repose on product claims: an absolute cutoff measured from when the product was first sold, regardless of when the defect was discovered or when the crash happened. Georgia's is ten years from the date of first sale for use or consumption, and it applies even to a strict liability claim over a latent defect that nobody could reasonably have found earlier.¹⁷ Unlike an ordinary statute of limitations, a statute of repose generally doesn't pause for minors, incapacity, or a late discovery of the injury. It's one of the few deadlines in this area of law that can expire before the injury it would cover ever happens.

The evidence has a shorter deadline than the law does

None of the legal deadlines above account for how fast physical evidence disappears. Modern vehicles capture pre-crash data through event data recorders, and a 2024 federal rule extended how much of that data has to be captured, from five seconds at two readings per second to twenty seconds at ten readings per second.¹⁸ That data still gets overwritten by later trips or lost entirely once a totaled vehicle is scrapped, often within weeks of the crash, long before any statute of limitations comes close to running. Dashcam footage and nearby security or traffic camera video are typically overwritten on a fixed loop, sometimes within days. None of that is governed by the statute of limitations at all. It's the practical argument for acting quickly even in a state that gives you years to file.

What happens if you miss it

If the deadline passes before a lawsuit is filed, the defendant's attorney raises the statute of limitations as an affirmative defense, and once the court confirms the date, the case is dismissed regardless of how strong the underlying claim was. Settlement leverage disappears well before that point, too. An insurance adjuster who knows your deadline has passed, or is about to, has no financial reason left to negotiate.

Because tolling rules, discovery-rule exceptions, government notice deadlines, and multi-state complications can all move your real deadline earlier or later than the general number for your state, don't rely on a chart to calculate your own. If a deadline might be close, or you're not sure which rule applies to your situation, get it checked. You can find an attorney through the legal directory.
