California Statute of Limitations for Car Accidents: How Long Do You Really Have to File?

If you were hurt in a car accident in California, a hard deadline started counting down the moment of the crash. Miss it, and it usually will not matter how serious your injuries were or how obviously the other driver was at fault. Your claim is gone. That deadline is called the statute of limitations, and for most car accident injury cases the California statute of limitations gives you two years to file a lawsuit.

Two years sounds like plenty of time. That is exactly why it catches people. The two-year rule is the part everyone half-remembers, but the exceptions are where real cases die. Some situations quietly cut your window down to six months. Others can pause the clock for years. And a few common assumptions, like thinking that opening an insurance claim protects your rights, are flat wrong and have cost people their entire case.

Here is how the deadlines actually work, which one applies to your situation, and the traps that send otherwise strong claims straight into the trash.

How the California Statute of Limitations Works for Car Accidents

A statute of limitations is a legal filing deadline. For personal injury, it is set by California Code of Civil Procedure section 335.1, which gives you two years from the date of the accident to file suit for injuries caused by someone else’s negligence. This covers the vast majority of crashes: rear-end collisions, intersection wrecks, pedestrian and bicycle injuries, motorcycle accidents, and multi-car pileups.

The clock is precise. If your crash happened on a Tuesday, your two years run out on that same calendar date two years later. File one day late and the defense will move to throw the case out, and the court almost always grants it. The deadline is jurisdictional, which is a formal way of saying the judge has no sympathy to give even when your injuries are severe and the other driver was clearly reckless.

Not every claim runs on the same two-year track, though. The deadline depends on what was damaged, who caused the harm, and who you are suing.

The Basic Filing Deadlines

Here are the core deadlines that come up after a California car accident.

Type of Claim	Deadline	Statute	When the Clock Starts
Injury to you or a passenger	2 years	CCP § 335.1	Date of the crash
Vehicle or other property damage	3 years	CCP § 338(c)	Date the property was damaged
Wrongful death	2 years	CCP § 335.1	Date of death, not the crash
Claim against a government agency	6 months to file the claim	Gov. Code § 911.2	Date of the crash
Injury from later medical treatment	1 year from discovery / 3 years outer limit	CCP § 340.5	When you discover the harm

A few of these deserve a closer look. Property damage gets a longer three-year window, but you should almost never wait that long to settle it. Because your injury claim expires first, and because filing your car repair claim and your injury claim separately can create legal problems, both are usually handled together inside the two-year window.

Wrongful death is measured differently. If a loved one survives the crash and passes away later from those injuries, the two years run from the date of death, not the date of the accident. That gives grieving families the full period to decide what to do.

The medical malpractice line matters more than people expect. If you are hurt in a crash and then a hospital or doctor makes your injuries worse through negligent treatment, that separate claim runs on a shorter, stricter clock under CCP section 340.5. It can expire well before your two-year car accident deadline, so it needs to be spotted early.

The Six-Month Government Deadline That Quietly Kills Cases

This is the single most common way people accidentally destroy their own case, so read it carefully.

If a government vehicle or agency played a role in your crash, the two-year rule does not apply to the first and most important step. Instead, the California Government Claims Act requires you to file a formal written claim with the correct agency within six months of the accident under Government Code section 911.2. Six months, not two years. Miss that window and your right to sue can vanish before you even realize a deadline was running.

When does this apply? More often than you would guess:

• A city bus, county vehicle, or Metro train was involved
• The other driver was a police officer, a city worker, or a state employee on the job
• A Caltrans truck or a government maintenance vehicle hit you
• A dangerous road condition, a broken traffic signal, a missing sign, or a pothole contributed to the crash
• A public school or transit district vehicle was at fault

The government claim is not a lawsuit. It is a written notice you must send before you are even allowed to sue. Once you file it, a specific sequence of shorter deadlines kicks in.

Step	Deadline
File your written claim with the agency	Within 6 months of the crash
Agency accepts, rejects, or stays silent	45 days to respond
If it mails a proper written rejection, you file suit	Within 6 months of that notice (Gov. Code § 945.6)
If it never sends proper written notice, you file suit	Within 2 years of the crash
Missed the 6-month claim? Ask permission to file late	Within 1 year of the crash (Gov. Code § 911.4)
Late request denied? Petition the court for relief	Within 6 months (Gov. Code § 946.6)

Notice the trap buried in that second-to-last row. If the agency mails you a rejection with the right warning language, your window to actually file the lawsuit shrinks to six months from the date of that letter, even if the two-year mark is still far away. People see “two years” in their head, set the letter aside, and blow the real deadline by months.

When the Clock Can Pause: Tolling and Exceptions

California law does recognize situations that pause, or “toll,” the statute of limitations. Courts read these narrowly, and you should never assume one applies to you without legal advice. Still, they are worth understanding.

The discovery rule. Some injuries do not show up right away. A traumatic brain injury can surface as memory and mood problems weeks later. Internal damage can stay hidden. When an injury is genuinely not discoverable at first, the clock may not start until you knew, or reasonably should have known, that you were hurt and that someone else caused it. This is not a loophole for waiting around. If you felt symptoms and ignored them, the rule will not save you. Serious injuries that take time to fully reveal themselves are also a big reason that a case can take longer to resolve than people expect.

Injured minors. If the injured person was under 18 at the time of the crash, the deadline for a standard claim against a private driver is generally paused until they turn 18, giving them until their 20th birthday to sue under CCP section 352(a). One massive exception, though: this protection does not extend the six-month government claim deadline. A child hurt by a city bus or on public property still has to meet that six-month requirement. The California Supreme Court made this painfully clear in J.M. v. Huntington Beach Union High School District (2017), where a student athlete’s serious injury claim was permanently dismissed because the government deadlines were missed, even though he was a minor the whole time.

Mental incapacity. If an injury or condition leaves someone legally unable to manage their own affairs, the clock can pause until that incapacity lifts, though it takes real medical proof.

Incarceration. A person in custody may get the deadline tolled for up to two years under CCP section 352.1.

Two older tolling ideas are worth a quick warning. There used to be an argument that a defendant leaving California pauses the clock, and there was a special tolling rule during the height of the COVID-19 pandemic. Both are now unreliable or expired for a normal two-year car accident claim, and neither is something to build a late filing around.

Hit-and-Run: Does an Unknown Driver Stop the Clock?

No, and this surprises people. Marketing pages love to suggest that if the at-fault driver fled and was never identified, your deadline waits for you. It does not. The California Supreme Court held in Bernson v. Browning-Ferris Industries (1994) that simply not knowing who hurt you is not enough to stop the clock.

What you can do instead is file your lawsuit on time against a “Doe” defendant, which is a placeholder for the unknown driver, under CCP section 474. If the driver is later identified, you amend the complaint to add their real name, and it relates back to your original on-time filing. Just as important, a hit-and-run usually triggers your own uninsured motorist coverage, which has its own separate deadline covered next.

Uninsured and Underinsured Motorist Claims Have Their Own Deadline

If the driver who hit you had no insurance, too little insurance, or fled the scene, your recovery often comes from your own uninsured or underinsured motorist coverage. These claims do not follow the ordinary court deadline, and getting this wrong is a classic and costly mistake.

For an uninsured motorist claim under Insurance Code section 11580.2, you generally have to take one specific action within two years of the accident: file a lawsuit against the at-fault driver, reach a formal settlement with your carrier, or formally demand arbitration in writing. Politely negotiating with an adjuster does not count and does not stop the clock.

Underinsured motorist timing works differently and is less of a clean bright line. It generally turns on when the underlying claim against the at-fault driver is resolved rather than a flat two-year date from the crash. Because the rules split between these two coverages, and because your own policy language matters, this is an area where a quick call to a lawyer early is genuinely worth it.

One Dangerous Myth: An Insurance Claim Does Not Stop the Clock

This one is worth saying plainly because it ends cases every year. Opening a claim with an insurance company, reporting the crash, and going back and forth with an adjuster for months does nothing to pause the statute of limitations. The court deadline runs on its own.

Insurers are not required to remind you that time is running out, and a settlement that feels close can fall apart the week before your two years expire. If that date passes without a signed settlement or a filed lawsuit, your leverage disappears completely, because the insurer knows you can no longer sue. Suddenly the “fair offer” evaporates. The deadline is what gives your claim its teeth.

What Happens If You Miss the Deadline

If the statute of limitations passes, your claim is barred. The other side files a motion, the court dismisses the case, and the strength of your injuries or the clarity of the other driver’s fault no longer matters. There is no appeal to fairness that fixes a missed deadline. This is also why the value of a strong claim, something we break down in our guide to what a California car accident case is worth, only exists while the deadline is still alive.

One related point for families. When someone passes away from crash injuries, California distinguishes between a wrongful death claim, brought by the family for their loss, and a survival action, brought by the estate for what the victim went through. As of January 1, 2026, a change in the law means survival actions filed on or after that date can no longer recover the deceased person’s pre-death pain and suffering. That shift makes acting promptly, rather than sitting on a potential claim, more important than ever in these cases.

How to Protect Yourself

You do not need to memorize statutes. You need to respect the calendar. A few habits go a long way:

• Assume the shortest possible deadline applies until a lawyer confirms otherwise, especially if any government vehicle, public road condition, or public agency might be involved.
• Get medical care right away and keep going, both for your health and because gaps in treatment let insurers argue you were not really hurt.
• Do not treat an open insurance claim as protection. It is not.
• Talk to a lawyer early, while there is still time to investigate, identify every possible defendant, and preserve your options.

Every case is different, and the deadline that governs yours depends on the specific facts. The safest assumption is that your window is shorter than you think.

Frequently Asked Questions

How long do I have to file a car accident claim in California?

For most car accident injury claims, you have two years from the date of the crash to file a lawsuit under CCP section 335.1. Claims for vehicle or property damage alone get three years. But if a government agency was involved, you may have only six months to file a formal claim, so the safe answer is to check your specific situation quickly.

What happens if I miss the statute of limitations in California?

Your claim is permanently barred. The defense will ask the court to dismiss it, and the court will, regardless of how serious your injuries are or how clearly the other driver was at fault. Once the deadline passes, you also lose all leverage to negotiate a settlement, because the other side knows you can no longer sue.

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

The two-year deadline applies to filing a lawsuit in court. It does not pause just because you opened an insurance claim or are negotiating with an adjuster. You must either settle or file suit before the deadline. Simply having an open claim does not protect your rights, and many people learn this the hard way.

Can I still file a claim if the at-fault driver fled and is unidentified?

Yes, but the clock does not wait for you. You generally file your lawsuit on time against a “Doe” defendant and substitute the driver’s real name if they are later identified. A hit-and-run also usually triggers your own uninsured motorist coverage, which carries its own two-year action requirement, so both deadlines need attention.

How long do I have to sue a city, the county, or a state agency?

You must file a written government claim within six months of the crash. If the agency rejects it in writing, you then generally have six months from that rejection notice to file your lawsuit. These deadlines are strict, and even injured minors are held to the six-month claim requirement.

Is there any way to extend the two-year deadline?

Sometimes. California recognizes limited exceptions, including delayed discovery of a hidden injury, tolling for minors, and tolling for legal incapacity. Courts apply these narrowly and you should never assume one applies without legal advice. Treat the standard deadline as firm and get your situation reviewed early.

Talk to a Lawyer Before the Clock Runs Out

The California statute of limitations is unforgiving, and the shorter deadlines are the ones that catch good people off guard. If you were injured in a car accident anywhere in Los Angeles or Southern California, the smartest move is to find out which deadline applies to you now, while you still have every option open.
