Car Accident Lawsuit Process

One moment you are driving home, and the next you are looking at a crumpled bumper, a police report number, and a call from an insurance adjuster who has already decided what your pain is worth. California recorded 4,061 traffic deaths in 2023, the latest finalized statewide crash data, according to the California Office of Traffic Safety (updated July 2025). The car accident lawsuit process moves through medical treatment, evidence gathering, a demand letter, and, if the insurer does not pay fairly, a filed lawsuit that ends in settlement or trial.

At California Trial Law Group, founding attorney Ike M. Kaludi and our California car accident lawyer team offer a free case evaluation within 24 hours, begin preserving evidence immediately before crash footage disappears, and build the medical and financial record a court needs.

Key Takeaways

The table below summarizes each stage of the process covered in this guide.

What Happens Immediately After a California Car Accident

A California car accident starts the clock on a set of deadlines before any lawsuit exists. Medical treatment documents your injuries, a police report establishes an official record, and the state requires certain accidents to be reported directly to the DMV. Here is a quick summary of what to do after a car accident in California:

1. See a doctor the same day. Adrenaline masks pain, and a same-day exam ties your injuries to the crash on the record.
2. Get the police report number before you leave the scene. Officers who respond record fault-relevant observations that insurers request later.
3. File a Report of Traffic Accident (SR-1) with the California DMV within 10 days if the crash caused injury, death, or property damage over $1,000. The DMV requires this report regardless of fault, separate from the police report and any insurance claim.
4. Photograph the scene, the damage on all vehicles, and any visible injuries before repairs or medical treatment changes what the evidence shows.
5. Notify your own insurer with the basic facts, and route further conversation with any insurer through your attorney.

Avoid admitting fault at the scene. A reflexive apology or a guess about what happened can be used against you later, even when the crash was not your fault.

How Long You Have to File a Car Accident Lawsuit in California

California gives most car accident victims two years from the date of the crash to file a personal injury lawsuit. The deadline changes by claim type and by defendant, and missing any of these windows ends the right to recover before a case is heard.

A crash involving a city vehicle, a public bus, or a pothole on a state highway carries the six-month government claim window described above. These deadlines apply whether or not the crash caused a physical injury, and a property-damage-only claim still qualifies for a lawsuit under the three-year window above, separate from the personal injury track. A California personal injury lawyer confirms which deadline applies before it becomes the reason a valid claim gets dismissed, and identifying whether a government entity is involved changes who the claim needs to name as a defendant.

Who You Can Sue After a California Car Accident

A car accident lawsuit can name the at-fault driver, the vehicle's owner, an employer, or a government entity, depending on who caused the crash and why.

1. The driver who caused the crash. Most claims start and end with the at-fault driver, the party whose negligence caused the collision.
2. The vehicle's owner, when that person was not driving. California Vehicle Code §17150 holds an owner liable, up to statutory limits, for injuries caused by anyone driving the vehicle with permission, including a friend or family member.
3. An employer may be liable if the at-fault driver was working at the time. California's respondeat superior doctrine holds an employer liable for an employee's negligent driving during the course of employment, common in company-vehicle and commercial delivery crashes. Rideshare and app-based delivery drivers are classified as independent contractors under Proposition 22, so a claim against Uber or Lyft runs through a separate legal theory rather than respondeat superior.
4. A government entity, if a public employee or a dangerous road condition caused the crash. This is the claim type that carries the six-month deadline described above.
5. More than one defendant, in a multi-vehicle crash. Each defendant answers for their own share of fault, an outcome shaped by the comparative negligence rules covered later in this guide.

Identifying every liable party early shapes how your attorney builds the claim from day one.

More than one party may owe you compensation, and most people miss at least one. Reach out to us at (888) 238-7562, and our team identifies every liable party in your crash before the statute of limitations narrows your options.

Building Your Claim Before You Sue

Your claim is built long before a lawsuit is filed, through medical documentation, an investigation, and a demand letter sent to the insurer.

1. Continue medical treatment until your symptoms resolve or stabilize. Insurers read gaps in treatment as evidence that an injury healed, and TBI and spine trauma are especially prone to producing hidden injuries after a crash that don't surface for days or weeks.
2. Preserve evidence before it disappears. Dashcam and traffic camera footage is commonly overwritten within days, and witness memory fades faster than most people expect.
3. Ask what to ask your lawyer before you hire one, including how that attorney handles cases that go to trial rather than settle quickly.
4. Let your attorney send the demand letter. The letter states the facts of the crash, the basis for fault, and the compensation requested, and it opens the negotiation that resolves most claims without a lawsuit.
5. Route every insurer conversation through your attorney. Insurance adjusters record statements and monitor claims for any inconsistency that reduces payout.

Filing the Lawsuit: Court and Alternative Dispute Resolution

A car accident lawsuit begins when your attorney files a complaint in California Superior Court, after settlement talks with the insurer fail to produce a fair offer.

1. The complaint names the at-fault party, states the facts of the crash, and details the damages sought.
2. A process server delivers the summons and complaint to the defendant, an official step called service of process.
3. The defendant responds within 30 days of being served, either admitting, denying, or raising defenses to the claims.
4. Discovery follows, and both sides exchange interrogatories, requests for documents, and depositions taken under oath. Complex or disputed cases often call for the role of expert witnesses, including accident reconstructionists and treating physicians.
5. Many cases move to mediation for personal injury disputes, confidential under California Evidence Code §1119 and often scheduled once discovery narrows the disputed facts. Mediation is one form of alternative dispute resolution, a category that also includes binding and non-binding arbitration for cases where both sides agree to skip a jury entirely.

If Your Case Goes to Trial

Most California car accident cases resolve before trial, through a negotiated settlement or a result reached in mediation. A case proceeds to trial when the insurer refuses a fair settlement and mediation does not close the gap between the parties. Jury trials in busier California counties can take 18 months or longer to begin after a case is filed, a scheduling reality separate from how long the trial itself lasts. At trial, a judge or jury hears the evidence, decides who caused the crash, and sets the compensation owed. A verdict can be appealed if either side identifies a legal error in how the trial was conducted, adding months or years before the case reaches a final result.

What This Process Can Mean for Your Recovery

California's pure comparative negligence rule lets you recover compensation even when you share some fault for the crash. A jury or insurer reduces your award by your percentage of fault rather than barring recovery outright, no matter how large that percentage is.

The table above reflects California's pure comparative negligence rule, which applies at every stage of the process, from the first insurance offer through a jury verdict. Even a driver found mostly at fault keeps a share of the recovery, a rule some states do not follow.

Compensation in a car accident claim covers medical bills, lost wages, property damage, and pain and suffering, and the total value depends on how well each item is documented through the process described above.

If an insurer is already shifting blame onto you, the percentage they assign changes what your claim is worth in real dollars.
