How Long Do You Have to Sue After a Car Accident?

What is the statute of limitations for a car accident?

The statute of limitations for a car accident is a hard legal expiration date on your right to sue. It doesn’t matter how serious your injuries were, how clear the other driver’s fault is, or how much evidence you have — miss this deadline and a judge will dismiss your case without looking at a single fact. Every state sets its own car accident filing deadline, ranging from as short as one year (Kentucky, Louisiana, Tennessee) to as long as six years (Maine, North Dakota).

Here’s the mistake people make most: this deadline is about filing a lawsuit in civil court. It has nothing to do with your insurance claim. Insurance companies have their own deadlines — usually 30 to 90 days — for reporting accidents and submitting claims. You can be actively negotiating a settlement and have the statute of limitations clock running against you the entire time.

The table below covers standard adult personal injury claims. The “Government vehicle notice” column is a completely separate, shorter deadline — missing it bars your claim even if the regular filing deadline hasn’t expired.

When does the car accident statute of limitations clock start?

In almost every state, the car accident filing deadline starts on the date of the accident itself — not when you discovered your injuries, not when the insurance company denied your claim, and not when you hired a personal injury attorney. The accident date is day zero.

There is a limited exception called the “discovery rule” — it can delay the start date if your injuries genuinely couldn’t have been discovered until later. But courts apply this very narrowly for car accidents, since the crash is usually an obvious event you know about immediately. Don’t assume this applies to your situation without consulting an attorney.

Five situations where the car accident filing deadline can change

• The victim was a minor at the time. Most states start the statute of limitations clock on the victim’s 18th birthday rather than the accident date, giving them until age 19 or 20 in a 1-year state. A parent’s separate claim for medical expenses, however, often still starts from the accident date.
• The at-fault driver left the state. Some states pause the personal injury lawsuit deadline while the defendant is absent, since you can’t easily serve them. This rule is less reliable than it sounds — verify with an attorney before counting on it.
• Legal incapacity. If the victim was in a coma or legally incompetent at the time of the accident, most states delay the start date until competency is restored.
• Wrongful death. The wrongful death statute of limitations usually starts from the date of death — which may be days or weeks after the accident date itself.
• Fraudulent concealment. If the at-fault driver actively hid their identity or the facts of the crash, courts in some states will extend the car accident lawsuit deadline. This is uncommon and hard to establish.

Government vehicles and a completely separate (shorter) deadline

This is the one that catches people off guard most. If a city bus, police car, mail truck, school bus, or any government-owned vehicle caused your accident, you face two deadlines: the standard car accident statute of limitations and a separate “notice of claim” deadline that is far shorter — typically 90 to 180 days.

Missing the government notice deadline doesn’t reduce your recovery — it completely bars your claim, even if the regular 2-year or 3-year car accident filing deadline hasn’t expired. If a government vehicle was involved in any way, treat this as urgent and contact a personal injury attorney within weeks.

Fault rules by state — why they affect your car accident claim

The statute of limitations tells you how long you have. Your state’s fault system determines whether you can recover anything at all if you were partially responsible.

Pure comparative negligence (about 12 states)

You can recover even if you were 99% at fault — your payout is reduced by your fault percentage. States include: Alaska, Arizona, California, Florida, Kentucky, Louisiana, Mississippi, Missouri, New Mexico, New York, Rhode Island, Washington.

Modified comparative negligence (most states)

You can recover only if you were less than 50% or 51% at fault (varies by state). At or above that threshold, you recover nothing — regardless of the other driver’s fault.

Contributory negligence — the strictest rule (5 jurisdictions)

Alabama, Maryland, North Carolina, Virginia, and Washington D.C. use the harshest standard: even 1% fault can bar your recovery entirely. In these states, having an attorney who can clearly argue fault is especially important.
