TL;DR: There is no single deadline for every California car accident injury claim. You should notify the appropriate insurer as soon as possible because insurance policies may have their own notice requirements. If you need to file a personal injury lawsuit, you generally have two years from the date of injury, which is usually the crash date. Claims against public entities usually require an administrative claim within six months. Uninsured motorist and hit-and-run claims have separate deadlines and notice requirements.
Highlights:
- Report the accident to the appropriate insurer as soon as possible.
- Check your insurance policy for any claim notice requirements.
- File most personal injury lawsuits within two years of the injury date.
- Present most injury claims against public entities within six months.
- Follow separate notice rules for uninsured motorist and hit-and-run claims.
- Preserve photos, videos, witness details, and medical records early.
Tip: Different deadlines can apply to the same accident, so identify both insurance and legal filing requirements early.

A car accident injury claim in California does not have a single universal deadline. Still, in most cases, you should act quickly because insurance claims should be reported as soon as possible after the crash. Many insurance policies also include their own notice requirements that can affect coverage if you wait too long.
Different types of claims can have different deadlines. A claim against a public entity usually requires formal notice within six months. Uninsured motorist and hit-and-run claims also have separate statutory requirements that may require early reporting and specific steps to preserve coverage.
If the injury claim cannot be resolved through insurance and you need to file a lawsuit, California generally allows two years from the date of injury under Code of Civil Procedure § 335.1. In most car accident cases, that means two years from the date of the crash.
Because multiple deadlines may apply simultaneously, it is important to report the accident and begin the claims process promptly to protect your rights and avoid missing any applicable filing requirements.
Starting early also helps preserve the evidence that car accident claims lawyers will need to review your case. Medical records and crash scene photos can be lost or altered in the weeks after a crash.
How Soon Should You File An Insurance Claim?
You should report a car accident to the appropriate insurance company as soon as possible. Your policy may contain notice requirements that affect whether or how coverage applies.
The California Department of Insurance advises drivers to notify their insurance agent or company immediately after an accident.
Depending on the situation, you may file a claim with:
- Your own insurance company
- The at-fault driver’s insurance company
- Both insurers, in some cases
After you report the accident, the insurer may request information about your injuries and losses. This can include:
- Medical records and medical bills
- Proof of lost income
- Photographs of the accident and injuries
- Other supporting documentation
There is an important distinction between an insurance claim and a lawsuit:
- An insurance claim is handled through the insurer.
- A lawsuit is filed in court.
Reporting a claim to an insurance company does not automatically preserve your right to sue. If negotiations continue without a settlement, the separate deadline for filing a lawsuit can still expire.
In some situations, the deadline may be extended by:
- A written tolling agreement, or
- Other legal tolling rules that apply under California law
If an unrepresented injured person receives an advance or partial payment, California Insurance Code § 11583 may also apply. In that situation:
- The payer must provide written notice of the applicable filing deadline.
- If proper notice is not given, the deadline may be tolled until notice is provided.
Knowing what a car accident lawyer does can help you understand which deadlines may apply to your claim. An attorney can review insurance notice requirements, track filing deadlines, and determine whether your case involves a shorter time limit, such as a claim against a public entity.
How Long Do You Have To File A Lawsuit If The Claim Does Not Settle?
If your injury claim is not resolved through insurance or settlement negotiations, you generally have two years from the date of injury to file a personal injury lawsuit under California Code of Civil Procedure § 335.1.
In most car accident cases, the “date of injury” is the date of the crash. However, there are some important exceptions and variations to keep in mind.
The general rule (most injury cases):
- You typically have 2 years from the date of the accident to file a lawsuit.
- This deadline applies to filing in court—not just opening a claim or notifying an insurance company.
- If you miss this deadline, you may lose your right to pursue compensation through the court system.
What the deadline does not mean:
- It is not the deadline to report the accident to the insurer.
- It is not the deadline to start a claim.
- It is not the deadline for settlement negotiations.
You can still negotiate with the insurance company right up until the lawsuit deadline expires—but waiting too long can create serious risks.
Important exceptions where the two-year rule may not apply or may be adjusted:
- Claims against government entities
- You usually must file an administrative claim within 6 months of the injury.
- If that claim is denied, you may then have a shorter window to file a lawsuit.
- Delayed discovery of injury
- In rare cases, the clock may start when the injury is discovered (or reasonably should have been discovered), rather than on the accident date.
- Minors (under 18)
- The statute of limitations is typically paused until the child turns 18, giving them more time to file.
- Defendant leaves the state
- If the at-fault party leaves California, the time they are gone may not count toward the deadline.
Why timing still matters even if you are negotiating:
Even though settlement talks can continue during the two years, waiting too long can hurt your case because:
- Evidence can disappear or degrade over time.
- Witnesses may become harder to locate.
- Medical documentation may be incomplete or delayed.
- Insurance companies may be less motivated to settle as deadlines approach.
Why starting early helps:
Beginning the process as soon as possible gives you more control over your case. It allows time to:
- Preserve key evidence from the crash.
- Gather complete medical records.
- Track ongoing treatment and expenses.
- Evaluate whether filing a lawsuit is necessary.
In short, while you may have up to two years to file a lawsuit, acting early helps protect your rights and strengthens your ability to recover full compensation.
Frequently Asked Questions About Car Accident Deadlines
These common questions explain how California deadlines can change after a car accident. The right deadline depends on the claim, defendant, and insurance coverage involved.
Can I Make An Insurance Claim After Two Years?
Possibly, depending on the policy, the type of coverage, and the circumstances. However, waiting two years can create serious problems because the separate deadline for filing a personal injury lawsuit may already have expired.
Reporting a claim to an insurer does not extend the lawsuit deadline. If a substantial amount of time has passed, the applicable insurance and legal deadlines should be reviewed separately.
How Soon Should I Report The Accident To My Insurance?
Report the accident to your insurer as soon as possible. The California Department of Insurance advises drivers to notify their insurance company immediately after a crash.
Your policy may contain additional notice requirements. Prompt reporting can also give the insurer time to investigate the collision and evaluate your claim.
What Happens If The Other Driver Was Uninsured?
If the other driver had no insurance, your uninsured motorist coverage may apply. California Insurance Code § 11580.2 generally requires you to take one of several steps within two years of the accident to preserve a UM claim. You must file a lawsuit against the uninsured motorist, reach an agreement on the amount due, or formally institute arbitration as required by the statute.
UM coverage may be unavailable if the named insured validly rejected the coverage in writing.
How Long Do I Have After A Hit-And-Run Accident?
A hit-and-run claim can involve much shorter notice requirements than an ordinary injury lawsuit.
For an uninsured motorist claim involving an unknown driver, California generally requires you to report the accident to law enforcement within 24 hours. You must also provide your insurer with a sworn statement within 30 days after that report.
California law also generally requires physical contact with the unknown vehicle for this type of UM hit-and-run claim. These requirements are separate from the broader deadline for filing a personal injury lawsuit.
What If My Injuries Appear After The Accident?
You may still pursue compensation for injuries that become apparent after the crash. However, discovering or diagnosing an injury later does not automatically reset the two-year period.
In most car accident cases, the lawsuit deadline still runs from the date of injury, which is usually the crash date.
You should report new symptoms to your medical provider and insurer promptly and avoid assuming that a delayed diagnosis extends any applicable deadline.
