After a crash, the deadline to take legal action is probably the last thing on your mind. You’re dealing with the car, the doctor, the insurance calls. But there’s a clock running from the day of the accident, and if it runs out, your right to compensation can vanish no matter how strong your case was. In California, the general rule for a car accident injury is two years. The full picture has more moving parts, and a few of them can shorten that window dramatically.
This guide lays out the deadlines that apply to California car accident claims, the exceptions that can lengthen or shorten them, and why waiting is risky even when you technically have time left. None of this is legal advice, and the right deadline for your situation depends on its specific facts.
The Two-Year Rule for Injuries
The core deadline is set by 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. That covers your bodily injuries, your pain and suffering, your lost wages, and your medical expenses. Miss it, and the court will almost certainly throw the case out, which is why two years is the number to keep in mind for most crashes.
It’s worth being clear about what the deadline governs. It’s the deadline to file a lawsuit in court, not the deadline to start a claim with the insurance company. You can and should open an insurance claim right away, long before the two years are up. People sometimes assume that because negotiations are ongoing, the deadline is on hold. It isn’t. The clock keeps ticking while you talk to the adjuster, and if those talks drag past two years without a lawsuit on file, you can lose your leverage entirely.
The Three-Year Rule for Property Damage
Damage to your vehicle is treated differently from damage to your body. Claims for property damage have a three-year deadline under Code of Civil Procedure section 338. In practice, the two often get resolved together, but if your injury claim and your car-repair claim somehow separate, they run on different clocks. The shorter one, your two-year injury deadline, is the one that usually matters most.
When the Deadline Is Much Shorter: Government Claims
Here’s the exception that catches people off guard. If a government entity contributed to your crash — you were hit by a city bus, a county truck, or a government vehicle, or a dangerous road condition played a role — you don’t get two years to start. Under the Government Claims Act, you generally must file a formal claim with the responsible public entity within six months of the accident. If that claim is denied, you then have a limited window to file suit. Six months is a fraction of the normal timeline, and missing it can end a government-related case before it begins.
Exceptions That Can Change the Deadline
The two-year rule has carve-outs. A few of the most common can move your deadline in either direction.
Injured Minors
When the injured person is a child, the clock generally doesn’t start until they turn 18. A minor hurt in a crash typically has until age 20 to file their own injury lawsuit. Claims tied to the child’s medical bills, which belong to the parents, can run on the ordinary schedule, so it’s not a reason to wait.
The Discovery Rule for Delayed Injuries
Sometimes an injury isn’t obvious right away. California’s discovery rule can delay the start of the clock until the date you discovered, or reasonably should have discovered, that you were harmed. This matters for injuries that surface late, but it’s narrower than people hope. Courts expect a reasonable person to investigate symptoms, so you can’t simply sit on a known injury and claim you discovered it later.
When the At-Fault Driver Leaves the State
If the person who hit you moves out of California before you can sue, the time they spend out of state may not count against your deadline. The clock can pause, or “toll,” while the defendant is absent. This is fact-specific, so it’s never something to rely on without checking.
What Happens If You Miss the Deadline
The consequence is blunt. If you file after the statute of limitations expires, the defendant will ask the court to dismiss your case, and the court almost always grants it. It doesn’t matter how clear the other driver’s fault was or how serious your injuries are. A late claim is usually a dead claim. This is the single most important reason not to let the deadline slip, and it’s why so many lawyers urge people to get advice well before the two years are up.
Why Waiting Hurts Your Case Even Before the Deadline
Even when you have time left, delay quietly weakens your claim. Evidence disappears. Skid marks fade, vehicles get repaired or scrapped, and surveillance footage gets overwritten, often within weeks. Witnesses move and memories blur. Insurers also read a long delay as a sign your injuries weren’t serious. There’s a practical side too: rushing a case together in the final weeks before a deadline leaves no room to investigate liability, line up medical opinions, or negotiate from a position of strength. The strongest claims are usually the ones where someone started gathering evidence early, well inside the deadline rather than racing against it.
Frequently Asked Questions About California Car Accident Deadlines
How long do I have to file a car accident lawsuit in California?
Generally two years from the date of the crash for injury claims, under Code of Civil Procedure section 335.1, and three years for vehicle property damage.
Does the two-year clock start at the accident or when I finish treatment?
Usually at the date of the accident. The discovery rule can sometimes delay the start for injuries that weren’t reasonably knowable right away, but that’s the exception, not the norm.
Is the deadline different if a city or government vehicle was involved?
Yes, and it’s much shorter. You typically must file a formal claim with the public entity within six months, then sue within a limited window after a denial.
What if the injured person is a child?
The deadline is generally tolled until the child turns 18, giving them until about age 20 to file. Parents’ claims for the child’s medical costs can run on the normal schedule.
Can I still negotiate with the insurance company after the deadline passes?
In practice, no leverage remains. Once you can no longer sue, the insurer has little reason to offer fair value, which is why the deadline protects your bargaining power, not just your day in court.
