Statute of Limitations for a Car Accident: How Long You Have to File

The statute of limitations for a car accident is the legal deadline to file a lawsuit over the crash. It is set by state law, it varies from state to state, and for personal injury it commonly runs somewhere between one and six years. If the deadline passes before you file, a court will usually dismiss the claim no matter how strong it is.

This guide is general information, not legal advice. Deadlines differ by state, differ by the type of claim, and change over time, so the safe move is to confirm the exact deadline with your state's statute or a licensed attorney. If the crash was not your fault, start with the steps to take when a crash was not your fault, then use this guide to understand the clock that is already running.

What is the statute of limitations for a car accident?

A statute of limitations is a law that bars a claim once a set period of time has passed after an injury. The Cornell Law School Legal Information Institute defines it as any law that "bars claims after a certain period of time passes after an injury," and notes that the length depends on the jurisdiction and the type of claim. For a car accident, it is the window during which you can file a lawsuit against the other driver or another responsible party.

The clock usually starts on the date of the crash. In some situations it starts on the date an injury was discovered, or the date it reasonably should have been discovered, a point covered further below. Once the period ends, the right to sue is generally gone, even if the other driver was clearly at fault. The deadline governs a lawsuit, so it is different from the shorter deadline your insurer sets for reporting the crash.

How long do you have to file a car accident claim?

There is no single national deadline. Each state sets its own limitations period, and for personal injury the typical range is about one to six years, measured in most cases from the day of the crash. Two verified examples show how much the number can move:

• In California, the deadline to sue for injury caused by another person's wrongful act or neglect is two years. California Code of Civil Procedure Section 335.1 sets the period as "within two years" for "injury to, or for the death of, an individual caused by the wrongful act or neglect of another."
• In Florida, an action founded on negligence must be brought within two years under Florida Statutes Section 95.11, subsection (5). Florida recently shortened this negligence window to two years, so an older guide that still lists a longer period would now be out of date, which is exactly why you confirm the current statute.

These two examples are not a stand-in for your state. Some states run shorter and some run longer, and a few set a different clock for particular defendants. Treat any number you read online as a starting point, then confirm the exact deadline that applies to your situation with your state's statute or a licensed attorney.

Are injury and property-damage deadlines the same?

Often they are different, even inside the same state. Many states give a longer window to sue over vehicle damage than to sue over a bodily injury, so the two clocks can expire on different dates from the same crash.

California is a clear illustration. The two-year injury deadline in Section 335.1 sits next to a separate three-year deadline for property damage. California Code of Civil Procedure Section 338 sets "within three years" for "an action for taking, detaining, or injuring goods or chattels," which covers damage to a vehicle. That means an injured California driver could have less time to file over their injuries than over their damaged car. Because the split and the exact lengths vary by state, check both the injury deadline and the property-damage deadline for the state where the crash happened, and confirm each with that state's statute or a licensed attorney.

Insurance deadline vs the lawsuit deadline: two different clocks

Reporting a crash to an insurer and filing a lawsuit run on two separate deadlines, and confusing them is a common mistake. Your insurance policy sets a prompt-notice requirement measured in days or weeks. The statute of limitations is set by state law and usually measured in years.

The policy deadline comes first and is usually much shorter. Most auto policies require you to report a collision "promptly" or "as soon as practicable," and a late report can jeopardize coverage even when the statute of limitations still has years left to run. The lawsuit deadline is the separate, longer clock this guide describes. You can meet your policy's notice window and still lose the right to sue later if you let the statute of limitations pass. If you are dealing with the other driver's insurer, the mechanics of filing a claim against the other driver are covered in a separate guide.

What is the discovery rule, and can the deadline be paused?

In some cases the clock does not start on the crash date, and in others it is paused for a period. Courts call the delayed start the discovery rule, and they call a pause tolling.

Under a discovery rule, the limitations period can begin when an injury is found, or when it reasonably should have been found, rather than on the day of the crash. The Cornell Law School Legal Information Institute notes that a period may run from "the date of the injury, the date it was discovered, or the date on which it would have been discovered with reasonable efforts." Tolling can also pause the clock for a person who was a minor at the time of the crash or who has a legal disability, which can extend the effective deadline. These rules vary widely by state and turn on the specific facts, so do not assume an exception applies to you. A licensed attorney in your state can tell you whether the discovery rule or tolling changes your deadline.

Are claims against a government entity different?

Usually yes, and the difference is significant. When a city bus, a county vehicle, a police car, or another government entity is involved, many states require a formal notice of claim within a much shorter window than the general statute of limitations, sometimes only a few months.

This notice-of-claim step is separate from and earlier than the lawsuit deadline. Miss it, and you can lose the right to sue the government entity even though the ordinary statute of limitations has not run. The exact deadline, the form of the notice, and who must receive it are set by each state and sometimes by each local agency. If any government vehicle or property may be involved in your crash, treat the timeline as urgent and confirm the specific notice rule right away with your state's statute or a licensed attorney.

What happens if the deadline passes?

If you file after the statute of limitations has run, the other side can ask the court to dismiss the case as time-barred, and courts routinely grant that request. The strength of your evidence does not change the outcome once the deadline is gone. That is why preserving proof early is worth the effort long before any clock runs out. The official crash report is a core piece of that proof, and you can get your crash report from the investigating agency through the directory. Requesting it early keeps the facts of the collision documented while witnesses, photos, and records are still fresh.

What to do next

Find the crash report and request it early so the evidence is preserved before any deadline lapses. Then confirm the exact statute of limitations for your state and your type of claim, because the deadline for injury and the deadline for property damage can differ. This guide is general information, not legal advice, and the specific figures above apply only to the states named. For the deadline that governs your situation, read your state's statute directly or consult a licensed attorney in your state.
