California Is a “Comparative Fault” State—Here’s What That Means

California follows a comparative fault-based system when it comes to car accidents and other injuries, which means determining who caused the crash is essential. This decision influences how claims are handled and how compensation is awarded. 

How it works in practice:

At-fault drivers are financially responsible

Under California law, if it is determined that a party is 100% liable for the crash, then they are responsible for covering the resulting damages. This includes vehicle repairs, lost wages, and medical expenses tied to a personal injury claim.

Insurance claims depend on fault 

After an accident, the at-fault party’s insurance is usually the first to pay for injuries and property damage.

Comparative negligence applies

California allows you to recover damages even if you were partly at fault. However, your compensation will be reduced by your percentage of fault under the pure comparative negligence rule.

How Fault Is Determined in a California Auto Accident

When it comes to proving fault in car accidents, evidence is everything. Attorneys and insurance companies rely on various forms of documentation to piece together what happened and who’s responsible. The stronger your evidence, the stronger your accident claim.

Here are the most common sources used to determine fault under California auto law:

Police reports and citations:

Officers who respond to the scene will document their observations, interview drivers and witnesses, and may issue citations for traffic violations. These reports often carry significant weight when determining fault.

Eyewitness statements

Testimony from bystanders, other drivers, or passengers can help clarify what happened, especially if there are conflicting versions of events.

Photos, videos, and vehicle damage

Visual evidence, like pictures of the vehicles, road conditions, skid marks, and intersection layout, can help reconstruct the accident and support your side of the story.

Traffic or surveillance camera footage:

 In some areas, public or private cameras may have recorded the collision, providing clear proof of how the crash occurred.

Dashcam recordings:

Footage from your own or another driver’s dashcam can offer an unbiased, real-time view of the moments leading up to the accident.

Accident reconstruction experts:

In more serious or disputed cases, experts may be brought in to analyze crash dynamics and determine fault based on vehicle positioning, impact points, and physics.

Medical records:

These help link injuries directly to the crash and provide a timeline that may support or challenge other evidence.

💡Tip: If you’re ever in a crash, take as many photos as possible and request a copy of the police report. These can be vital if a fault is disputed.

Negligence and Fault in California Car Accidents

In California auto accidents, assigning fault often hinges on whether a driver acted with reasonable care. If someone’s careless or reckless behavior caused the crash, they may be legally considered negligent, and that plays a major role in how much compensation is available to everyone involved.

Here’s how negligence fits into your accident claim:

  • Negligence is just a legal word for being careless or reckless behind the wheel: When someone’s carelessness causes an accident, that driver might be considered negligent for speeding, ignoring traffic signals, driving under the influence, or texting while driving.

  • Proving negligence is key to your accident claim: To succeed in your claim, you must show that the other driver breached a legal duty to drive safely, and that breach directly caused your injuries or losses.

  • Negligence impacts your compensation: You can still recover compensation even if you were partly at fault, but your payout will be reduced by the percentage of blame assigned to you. Don’t wait too long to act.

Even a small percentage of negligence assigned to you can significantly affect your payout. Consult our lawyers before you talk to an insurer or admit fault.

Building a Strong Accident Claim

The steps you take after a car accident can directly affect the strength of your claim. Acting quickly and strategically not only helps prove fault but also protects your right to full compensation under California law.

Here’s how to build a solid foundation for your accident claim:

  • Gather evidence immediately: Snap photos, collect contact information from witnesses, and save any dashcam footage. If you’re unsure what to do in the moments after a crash, check out our guide on what to do after a car accident in California.

Frequently Asked Questions

How is fault determined in a car accident under California auto law?

Fault in car accidents is determined by examining all available evidence, including police reports, witness statements, video footage, vehicle damage, and sometimes expert analysis. California auto law follows a comparative fault-based system, meaning each party may be found liable for a certain percentage, and that percentage makes a huge difference in compensation. Our team of lawyers knows what insurance companies think and what they look for when determining fault. We use this expertise to make sure our clients’ rights are protected and they receive the compensation they deserve.

How do you prove you are not at fault in a car accident?

To prove you were not at fault, gather solid evidence like dashcam footage, eyewitness statements, photos of the scene, and a copy of the police report. You may also refer to California traffic laws to show how the other driver acted negligently. Our experienced attorney at Court House Lawyers can help organize this evidence to support your claim.

Can I still file an accident claim if I was partially at fault?

Yes. California follows a pure comparative negligence rule. This means you can still file an accident claim and recover compensation even if you were partially at fault. However, your settlement will be reduced by your percentage of responsibility.

What qualifies as negligence in a car accident case?

Negligence refers to a driver’s failure to use reasonable care while driving. Common examples include speeding, distracted driving, failing to yield, or running a red light. Proving negligence is essential to holding the other party legally accountable in an accident claim.

What happens if both drivers are at fault in a California car accident?

If both drivers share fault, compensation is divided based on each party’s percentage of negligence. For example, if you are found to be 30% at fault, your total compensation will be reduced by that amount. This is part of California’s comparative fault system.

Is a police report required to file an accident claim in California?

While not required, a police report can strongly support your accident claim. It provides an official and impartial third-party account of the incident, which can be helpful when proving fault. You can request a copy from the law enforcement agency that responded to the scene.

How long do I have to file a car accident claim in California?

Under California auto law, you generally have two years from the date of the accident to file a personal injury claim and three years for property damage. However, exceptions may apply, so it’s best to speak with a personal injury attorney as soon as possible.
