How Long After a Car Accident Can You Claim an Injury in California?

This question usually comes from a specific person: someone who walked away from a crash feeling shaken but okay, and now, a week later, cannot turn their neck or is waking up with numbness in an arm. The good news is that the law anticipates you. The caution is that the calendar contains more than one deadline, and the most dangerous ones are the short ones nobody mentions.

Delayed Injuries Are the Norm, Not the Exception

Crash physiology explains the gap: adrenaline and stress hormones suppress pain for hours or days, and the injuries most common in collisions, soft tissue damage, whiplash, disc injuries, mild concussions, are precisely the ones that surface gradually. Stiffness on day three, headaches in week two, radiating pain in week four: these patterns are medically documented and insurance adjusters know them perfectly well, which does not stop adjusters from arguing that a gap in treatment means you were never hurt. The answer to that argument is written in your medical records, which is why the single most important thing a delayed-symptom victim can do is see a doctor now and say clearly that the symptoms followed the accident.

The Two Year Rule, and What Can Shorten It

California’s statute of limitations for personal injury is generally two years from the date of injury. In limited situations where an injury genuinely could not have been discovered right away, the discovery rule can adjust the start date, though courts apply it narrowly in car accident cases, so treat the crash date as your clock. What matters more are the deadlines hiding inside the two years. If any public entity is involved, a city vehicle, a government employee driving for work, a dangerously designed or maintained road, California requires a formal government claim within six months, and missing it usually ends the case before it begins. Your own policy also imposes prompt notice requirements for reporting the crash and for uninsured motorist claims, and property damage claims run on their own schedule.

Why Waiting Costs Money Even When It Costs You Nothing Legally

Suppose you wait five months, safely inside every deadline. You have still paid a price. The insurer now has a five month treatment gap to wave at a jury. Witnesses have scattered and camera footage is gone. Your memory of the crash has softened. And the medical connection between accident and injury, the causation that is the spine of your claim, is now an argument instead of a record. Deadlines define when a claim dies; evidence defines what it is worth, and evidence decays much faster than two years. If an insurer senses you are approaching the deadline unrepresented, expect the lowball to arrive precisely then, a pattern we describe in our guide to insurance bad faith in California.

What to Do If Your Symptoms Just Appeared

See a doctor immediately and describe the accident and the timeline honestly. Follow the treatment plan without gaps. Gather what still exists: photos, the police report, the other driver’s information, repair records. Report the crash to your insurer if you have not, sticking to facts and declining recorded statements for the other side. Then have an attorney map your actual deadlines, because which clocks apply depends on who hit you and what coverage exists, and the answer changes the entire strategy. The first steps after any crash are covered in our step by step California car accident guide, and our personal injury practice offers free consultations, so finding out where you stand costs nothing.
