How long you have, in plain terms
- Most states give you two years from the date of the accident.
This is the most common deadline — the "statute of limitations" — for filing an injury claim.
- But it varies: some states give only one year, others three or more.
Kentucky and Tennessee are as short as one year; Maine and North Dakota allow up to six.
- Some deadlines are much shorter.
If a government vehicle was involved, you may have only a few months to give formal notice — far less than the usual limit.
- The clock usually starts the day of the accident.
Waiting eats into your time and makes evidence harder to gather. There's rarely an upside to delay.
"How long do I have?" is one of the first practical questions after an accident, and the honest answer is: it depends on where you live and what kind of claim it is. Below is how the deadline works, the situations that change it, and why filing isn't the same as settling.
A deadline you don't know about is the one that hurts you. If there's any chance you'll make a claim, it's worth knowing your state's limit early.
What a "statute of limitations" actually is
A statute of limitations is simply a legal deadline. Each state sets its own time limit for filing a personal-injury lawsuit after an accident. If you miss it, the court can dismiss your case no matter how clearly the other driver was at fault — so the deadline matters as much as the facts.
It depends on your state
The single biggest factor is which state's law applies — usually the state where the accident happened. Two years is the most common limit, but it ranges from one year to six. Our by-state guide breaks down the deadlines and the exact statutes:

In most cases the clock starts on the date of the accident. There's a limited exception — the "discovery rule" — for injuries that genuinely couldn't have been known right away, where the clock may start when the injury is (or reasonably should have been) discovered. It's narrower than people hope, though: if a reasonable person would have seen a doctor and connected the injury to the crash, courts generally expect that. The safe assumption is that your time runs from the day of the accident.
Situations that change the deadline
- Claims involving a government vehicle. If a city, county, state or federal vehicle was involved, a much shorter notice deadline often applies — sometimes just a few months — before you can even bring a claim. These are strict.
- Injured minors. For a child, many states "pause" (toll) the clock until they turn 18, though the rules differ and it's not a reason to wait.
- Wrongful death. Claims after a fatal accident usually run on their own separate deadline, often from the date of death.
Because these can shorten your window dramatically, they're exactly the situations where it's worth getting advice early.
Filing isn't the same as settling
An important point that catches people out: you don't have to have finished treatment or know the final value of your claim to file. Many claims are settled through negotiation without ever going to trial — but the lawsuit is often filed shortly before the deadline to protect your rights while those negotiations continue. In other words, the deadline is about preserving the option, not forcing a courtroom.

- Most states give two years from the accident; some give one, some up to six.
- Government-vehicle claims can have a notice deadline of only a few months.
- The clock usually starts the day of the accident; the discovery rule is narrow.
- Filing protects the deadline — you can still settle by negotiation.
- If there's any chance you'll claim, check your state's deadline early.
