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

If you’ve been injured in a car accident in California, the answer most people get is “two years.” That’s mostly right — but it’s also where most people stop, and it’s where serious mistakes happen. The two-year rule has critical exceptions that can shorten your deadline to as little as six months, or extend it well beyond two years. This guide explains the actual rules, the exceptions, and what to do if you’re worried you may be running out of time.

California’s Standard Two-Year Statute of Limitations

Under California Code of Civil Procedure section 335.1, you generally have two years from the date of the accident to file a personal injury lawsuit against the at-fault driver. The clock starts on the date of the crash itself, not the date you finished medical treatment, not the date the insurance company denied your claim, and not the date you decided to hire a lawyer.

“Filing a lawsuit” means filing a formal civil complaint with the appropriate California Superior Court. It does not mean negotiating with the insurance company, sending a demand letter, or filing an insurance claim. Pre-lawsuit negotiations do not stop the statute of limitations from running. Many people lose their right to sue while waiting on a settlement that never comes.

Critical Exceptions That Shorten Your Deadline

Government vehicles and public entities — six months. If your accident involved a city bus, a county fire truck, a state highway maintenance vehicle, a public school bus, or any other publicly owned vehicle, you do not have two years. Under the California Government Claims Act (Government Code section 911.2), you must file an administrative tort claim with the appropriate public entity within six months of the date of the accident. If the entity denies the claim or fails to respond, you then have a separate, shorter deadline to file a lawsuit. Missing the six-month deadline almost always means losing your claim entirely, regardless of how serious your injuries are.

Wrongful death — two years from date of death. If a loved one died as a result of an accident, the wrongful death statute of limitations runs for two years from the date of death, which may be different from the date of the accident if the victim survived for a period of time before passing.

Property damage — three years. California gives a longer window for property damage claims (three years from the date of the accident). However, most accident-related property damage claims are resolved through insurance long before the deadline becomes relevant.

Exceptions That Can Extend Your Deadline

Minors. California’s statute of limitations is “tolled” — paused — while the injured person is under 18. The two-year clock does not start until the minor’s 18th birthday. A child injured at age 12 has until age 20 to file suit.

Mental incapacity. If the injured person is legally incompetent at the time of the accident or becomes so as a result, the statute of limitations is tolled until competency is restored.

Defendant out of state. If the at-fault driver leaves California after the accident, the time they spend out of state generally does not count toward the two-year period.

Delayed-discovery rule. If your injury was not — and could not reasonably have been — discovered immediately, the statute of limitations may begin running on the date of discovery instead of the date of the accident. This rule applies most often in cases involving latent injuries, internal trauma, or psychological harm. It is fact-specific and almost always requires legal analysis.

Why Waiting Hurts Your Case Even If You’re Within the Deadline

Even if you have time left on the clock, waiting to investigate or pursue a claim damages your case in real ways:

Evidence disappears. Vehicles get repaired or scrapped. Surveillance footage gets overwritten on a 30- to 90-day cycle. Skid marks fade. Roadway conditions change.
Witness memories fade. Eyewitnesses forget details, move away, or change their phone numbers. The longer you wait, the harder they are to find and the less reliable their testimony becomes.
Insurance companies lock in low settlements. Insurers know that a claimant who has been dealing with the case for a year is tired and more willing to accept a lowball offer.
Medical causation becomes harder to prove. If you delay treatment or have gaps in your medical records, defense attorneys argue that your injuries were caused by something other than the accident.

What to Do If Your Accident Was Months or Years Ago

If you’re reading this and the accident happened a while ago, do this immediately:

Calculate your deadline. Note the date of the accident, then count two years forward — or six months if a government entity was involved.
Write down everything you remember about the accident, your injuries, and the medical treatment you have received. Memory deteriorates fast.
Gather what you still have. Police reports, photos, medical bills, insurance correspondence, and any communications with the at-fault driver or their insurer.
Contact a California personal injury attorney for a free case evaluation. An attorney can quickly determine whether you still have a viable claim and what needs to happen to preserve it.

Frequently Asked Questions

Does negotiating with insurance count as “filing a claim” under the statute of limitations?
No. Pre-lawsuit insurance negotiations do not stop the two-year clock from running. Only a formal civil complaint filed with the appropriate court stops the statute.

What if I didn’t realize I was hurt until weeks after the accident?
California’s delayed-discovery rule may help, but it is fact-specific and not automatic. Speak with an attorney as early as possible if you have late-emerging injuries.

Can the deadline be extended if the insurance company is still actively negotiating?
Generally, no. Some insurers will offer a written tolling agreement that pauses the deadline, but they are under no obligation to do so. Never assume good-faith negotiation will protect your filing rights.

What if the at-fault driver was uninsured or fled the scene?
You may still have rights against your own insurance company under uninsured motorist (UM) coverage, but most policies require prompt notice. UM claims are subject to their own deadlines, often shorter than the standard two-year personal injury statute.
