California accident laws determine fault and compensation after a motor vehicle collision. With 164,596 injuries and 3,751 fatalities from crashes in 2024 alone, understanding these rules is critical. Key principles include:
The aftermath of an accident is overwhelming, with injuries, insurance claims, and legal deadlines creating immense pressure. A misstep can jeopardize your right to fair compensation.
I'm Tim Burd, founder of Justice Hero. We specialize in helping accident victims understand their rights and connect with qualified legal help. This guide simplifies California's accident laws, explaining fault, deadlines, and the steps you must take to protect your claim.

California operates under an "at-fault" system, also known as a tort system. This means the driver who negligently caused the accident is legally responsible for covering the resulting damages, including injuries and property loss. This differs from "no-fault" states, where each party typically turns to their own insurance first.
However, fault is not always 100% on one driver. California uses a pure comparative negligence rule to handle situations of shared blame. This legal doctrine is a cornerstone of California accident laws. For a broader look at how these principles apply, see our guide on Motor Vehicle Accident Laws.

After a crash, insurance companies and courts determine fault by identifying which driver was negligent—meaning they failed to use reasonable care. The at-fault driver's insurance is then liable for the damages.
As the injured party, you will typically file a third-party claim with the at-fault driver's insurer. This is distinct from a first-party claim filed with your own insurer, such as for collision coverage. The burden is on you to prove the other driver's negligence caused your injuries, which is why understanding the Auto Accident Claims process is so important.
Under California's pure comparative negligence rule, you can recover damages even if you were partially to blame. Your total compensation is simply reduced by your percentage of fault.
For example, if another driver runs a red light and hits you, but you were speeding, a jury might find the other driver 80% at fault and you 20% at fault. If your total damages are $100,000, you would receive $80,000 ($100,000 minus your 20% share of fault).
What makes California's system "pure" is that there is no cutoff. Unlike in some states, you can recover damages even if you are found 99% responsible. This ensures shared fault doesn't automatically bar you from compensation. However, expect the other driver's insurer to try to assign you a higher percentage of fault to reduce their payout.

In California's at-fault system, determining who was negligent is the key to a successful claim. Insurance adjusters and, if necessary, courts will conduct a detailed investigation to reconstruct the accident and assign responsibility. To secure compensation, you must prove the other driver's negligence caused your losses. Our Car Accident Legal Advice resource offers guidance on building a strong case from the start.

A strong case is built on solid evidence. The following are crucial for proving fault:
Certain accident types have predictable fault patterns under California accident laws:
After a car accident, you're on the clock. Missing key deadlines under California accident laws can permanently bar you from receiving compensation. Understanding these time limits is essential to protecting your rights. For a full overview, our guide to the Car Accident Lawsuit Process details each step.

In California, you must report a crash to the DMV by filing an SR-1 form within 10 days if it resulted in any injury, death, or property damage over $1,000. This applies to all involved drivers, regardless of fault.
The official SR-1 form can be submitted online. Failure to file on time can lead to the DMV suspending your driver's license. This requirement is separate from reporting the accident to the police or your insurance company.
The statute of limitations is the legal deadline for filing a lawsuit. If you miss it, you lose your right to sue.
Key exceptions can alter these deadlines:
These deadlines are strict. Consulting an attorney promptly ensures all time limits are met. Our guide to Personal Injury Litigation provides more detail on the legal process.
The moments following a car crash are chaotic, but your actions can significantly impact your ability to recover compensation under California accident laws. Adrenaline can mask serious injuries like whiplash, so taking the right steps is crucial for both your health and your legal claim. Our guide on Whiplash Injury Compensation explains why immediate medical care is so important.
Under California accident laws, you are entitled to seek compensation to make you "whole" again after a crash caused by someone else's negligence. However, insurance companies are businesses focused on minimizing payouts. Understanding the damages you can claim and the value of legal help is key to a fair outcome. For insight into typical outcomes, see our resources on Motor Vehicle Accident Lawsuit Settlements.

Damages are categorized to cover all your losses:
Economic Damages: These are tangible financial losses with a clear monetary value. They include all past and future medical bills, lost wages and earning capacity, property damage (vehicle repairs or replacement), and other out-of-pocket expenses.
Non-Economic Damages: These compensate for the non-financial, personal toll of the accident. They include pain and suffering, emotional distress (anxiety, PTSD), loss of enjoyment of life, and loss of consortium (impact on a spousal relationship).
Punitive Damages: Reserved for rare cases of extreme recklessness or malice, such as a crash caused by a repeat DUI offender. These are intended to punish the defendant and deter similar conduct, not just compensate the victim.
The value of your claim depends on the severity of your injuries and the specific facts of your case. Our Car Accident Lawsuit Payout Guide offers more detail on how these values are determined.
While you can handle a minor claim alone, an attorney is essential when injuries are involved. A lawyer protects your interests by:
The aftermath of a car accident leaves most people with more questions than answers. Here are concise answers to some of the most common concerns regarding California accident laws.
California law requires all drivers to carry liability insurance. The minimums, often called "15/30/5 coverage," are:
These minimums are dangerously low and often insufficient to cover the costs of a serious accident. It is highly recommended to carry higher limits, as well as Uninsured/Underinsured Motorist (UM/UIM) coverage. The California Department of Insurance provides more details on coverage options.
This is a frustrating but common scenario. Your primary source of recovery will be your own insurance policy, provided you have the right coverage:
While you can sue the at-fault driver personally, collecting a judgment from someone without insurance or assets is often impossible. This is why carrying adequate UM/UIM coverage is critical.
No. You should politely decline to provide a recorded statement to the other driver's insurance company without first consulting an attorney. The adjuster's goal is to minimize their company's payout, and they are trained to ask questions that can be used to weaken your claim.
Anything you say can be taken out of context to argue that your injuries are not severe or that you were partially at fault. You may also be unaware of the full extent of your injuries when they call. It is best to let your attorney handle all communications with the opposing insurer. Our Auto Accident Legal Advice guide offers more tips on navigating these conversations.
