How Long Do You Have to File a Car Accident Lawsuit? Deadlines by State

Published: March 12, 2026 · Last updated: March 12, 2026

TL;DR: Every state sets a deadline — called a statute of limitations — for filing a personal injury lawsuit after a car accident. Most states give you two to three years. Louisiana changed from one year to two years effective July 1, 2024. Maine and North Dakota give you six. Miss the deadline and you lose your right to sue. Government-vehicle accidents have even shorter notice deadlines (60 to 180 days). Check your state below and consult an attorney well before the deadline. Deadlines are subject to change — verify with a licensed attorney in your state.

The clock starts the day of your accident — in most cases.

If you were hurt in a car crash and haven’t resolved your claim, you are working against a legal deadline called the statute of limitations. In most cases, once it expires, the court will refuse to hear your case. Courts generally do not make exceptions based on how badly you were injured, how clear the other driver’s fault was, or how much your medical bills total. A missed deadline is typically the end of the road.

This guide tells you the specific deadline in every state, explains the exceptions that can extend or shorten that window, and tells you why waiting until near the deadline is a strategy that reliably backfires.

Important: The deadlines below reflect the law as understood in early 2026. Statutes of limitations are subject to legislative change and court interpretation. Several states have changed their deadlines in recent years. Always verify your specific deadline with a licensed personal injury attorney in your state before relying on any figure in this table.

Statute of Limitations by State — Personal Injury (Car Accidents)

Important Exceptions That Can Shorten Your Deadline

Government Vehicles: Much Shorter Deadlines

If the other vehicle was operated by a government employee — a city bus, a county sheriff’s deputy, a postal worker in a federal vehicle, a state road crew — different rules apply, and the deadlines are far shorter.

Most states require you to file a formal notice of claim with the relevant government entity before you can sue. These notice deadlines are not the same as the statute of limitations:

• Federal government (USPS vehicle, military vehicle, federal agency): You must file an administrative claim under the Federal Tort Claims Act within 2 years of the accident before suing.
• State government vehicles: Most states require notice within 6 months to 1 year. Examples: California requires a government tort claim within 6 months. New York requires a notice of claim within 90 days for claims against municipalities.
• Municipal vehicles (city, county): Often the shortest notice periods. Some are as short as 30 to 180 days.

Missing a government notice deadline can permanently bar your claim against that entity, even if the standard statute of limitations hasn’t run. If the other vehicle was government-operated, treat this as an emergency and consult an attorney immediately.

Important Exceptions That Can Extend Your Deadline

The Discovery Rule

In most states, the statute of limitations begins running when you knew or reasonably should have known that you were injured and that the injury was caused by the accident. For most crash injuries, this is the date of the accident itself. But for delayed-onset injuries — internal injuries, spinal damage, TBI complications — a court may find that the clock didn’t start until the injury became reasonably discoverable.

The discovery rule is narrow. Courts don’t use it generously for common injuries that should have prompted a doctor visit. If you felt any symptoms after the crash but waited years to see a doctor, the rule is unlikely to save you. But if a serious injury genuinely couldn’t have been detected until a specific diagnostic finding, it may extend your window.

Minors (Under 18)

In virtually every state, the statute of limitations is tolled (paused) for minors until they reach the age of 18. A 15-year-old injured in a car accident typically has until their 20th birthday to file (age 18 + 2-year statute). Confirm the specific rule in your state, as a few states have their own minor-tolling formulas.

Mental Incapacity

If the injured person was legally incapacitated at the time of the accident, most states toll the statute of limitations until the incapacity is removed.

Defendant Left the State

In some states, if the at-fault driver leaves the state after the accident, the time they are absent is not counted against the statute of limitations. This tolling provision is not universal — check your state’s law.

Why Waiting Until Near the Deadline Is a Bad Strategy

The statute of limitations tells you when you can no longer file a lawsuit. It says nothing about when you should. Waiting until the last few months of your deadline creates serious practical problems:

Evidence degrades. Surveillance footage is overwritten within days or weeks. Witness memories fade. Skid marks wash away. The earlier you preserve evidence, the stronger your case.

Medical records take time to gather. Building a damages case requires organized medical records from every treating provider. Assembling those records can take months.

Attorneys need time to investigate. A case filed one week before the deadline forces your attorney to file a “protective” complaint — a bare-bones filing that preserves your rights but doesn’t give time for proper investigation, which weakens settlement leverage.

Settlement negotiations work better with time. Insurers know when your deadline is. If you’re negotiating two weeks before it expires, they know you have no time to litigate and may hold firm on low offers. With years left, you have real leverage to say no and wait for a better number.

The practical guidance: treat the deadline as a backstop, not a target. Consult an attorney within weeks or months of the accident, not weeks before the deadline.

Property Damage vs. Personal Injury: Different Deadlines

Most people focus on the personal injury statute of limitations, but note from the table above that property damage claims often have different — sometimes longer — deadlines. If you’re only pursuing a property damage claim (vehicle repair or replacement) and have already missed the personal injury deadline, check whether your state’s property damage window is still open.

That said, if you have personal injuries, the personal injury deadline is the critical one. Property damage claims are typically smaller and easier to resolve quickly with the insurer; it is personal injury claims that require legal attention and are most likely to end in litigation.

Frequently Asked Questions

Does the statute of limitations apply to insurance claims or only lawsuits?

The statute of limitations applies to filing a lawsuit in court. There is technically no legal deadline for filing an insurance claim — you could file a claim the day before the limitation expires. However, most insurance policies include their own “prompt notice” requirements, and unreasonable delays in reporting can give the insurer grounds to deny coverage. File your claim as soon as practicable.

What happens if I miss the deadline?

In most cases, the other party will file a motion to dismiss based on the statute of limitations, and the court will grant it. Rare exceptions may exist depending on your state and specific facts, but courts generally do not override a missed statutory deadline based on the merit of a claim, severity of injury, or financial hardship. Consult an attorney immediately if you are near or past the deadline.

I settled my property damage but not my injury — does the clock still run?

Yes. Accepting a property damage settlement does not stop or reset the personal injury statute of limitations. If you signed a property damage release that was overly broad (releasing all claims from the accident), consult an attorney immediately to review what you actually signed.

Can the insurance company waive the statute of limitations?

Generally no. An insurer cannot extend the statutory deadline through its own conduct. However, if an insurer’s misrepresentation or active concealment caused you to miss the deadline, some courts have recognized equitable estoppel arguments. These are narrow, difficult to establish, and vary by state. Do not rely on this possibility — consult an attorney well before the deadline.

The Bottom Line

Your deadline is real, and courts enforce it without flexibility. If you were injured in a car accident, find out exactly how much time you have in your state from the table above, and contact an attorney well before that date — not on it.
