If you are involved in a car accident in Los Angeles, California, determining who is responsible for the collision can be one of the most important parts of your injury claim. Fault can affect whether you receive compensation, how much compensation you may recover, and how an insurance company evaluates your case.

California follows a pure comparative negligence system. This means you may still be able to recover damages even if you share some responsibility for an accident. However, your compensation can be reduced according to your percentage of fault.

Because fault is not always obvious, you should understand how responsibility is evaluated, what evidence can support your position, and what steps you can take after a crash.

What Does Fault Mean in a California Car Accident?

Fault generally means legal responsibility for causing an accident. In many California car accident cases, fault is based on negligence.

You may establish negligence by showing that another driver:

Had a responsibility to operate the vehicle safely.
Failed to use reasonable care.
Caused or contributed to the collision.
Caused injuries, property damage, or other legally recoverable losses.

For example, if another driver runs a red light and crashes into your vehicle, evidence showing that the driver ignored the traffic signal may support your claim that the driver was responsible.

However, some accidents involve several contributing factors. Another driver may have been speeding while you were changing lanes, or poor road conditions may have affected both drivers. That is why fault should be evaluated using the complete circumstances of the collision.

California Uses Comparative Negligence

California's comparative negligence rules allow you to seek compensation even when you are partly responsible for an accident.

For example, suppose you have $100,000 in legally recoverable damages and are found to be 20% responsible for the collision. Your potential recovery could be reduced by 20%, leaving $80,000.

This means you should not automatically assume that being partially responsible prevents you from pursuing compensation.

The percentage of fault assigned to each person can become an important issue when an insurance company disputes your claim. You should gather evidence that accurately explains what happened instead of accepting an unsupported percentage of responsibility.

Evidence Used to Determine Fault

Fault is usually determined by examining multiple sources of evidence. The more clearly the evidence establishes what happened, the easier it may be to evaluate responsibility.

Police Reports

A police report may contain information about the accident location, statements from drivers and witnesses, traffic violations, road conditions, and the responding officer's observations.

Although a police report can be valuable, it does not automatically determine legal liability. Additional evidence may change how responsibility is evaluated.

Photographs and Videos

If you can safely do so, take photographs of:

Vehicle damage
The accident scene
Road conditions
Traffic signals and signs
Skid marks
Debris
Visible injuries
Nearby vehicles or property damage

Dashcam recordings, traffic-camera footage, security cameras, and other video evidence may also help establish how the collision occurred.

You should preserve original photographs and videos whenever possible.

Witness Statements

Independent witnesses can provide important information about what happened before and during a collision.

A witness may have seen another driver speeding, using a cellphone, running a traffic signal, making an unsafe lane change, or failing to yield.

If you can safely obtain witness names and contact information, keep those details with your accident records.

Vehicle Damage

Damage to the vehicles can sometimes provide clues about the direction, speed, and manner of impact.

Photographs, repair estimates, inspection reports, and other documentation may help explain how the collision occurred. You should keep copies of repair estimates and invoices related to the accident.

Electronic Evidence

Modern vehicles and surrounding infrastructure may produce additional evidence. Depending on the circumstances, this can include dashcam recordings, surveillance footage, GPS information, and certain vehicle data.

You should act promptly when you believe relevant video or electronic evidence exists because some systems may automatically delete older recordings.

Traffic Violations Can Help Establish Fault

A driver's violation of California traffic laws may be important when determining responsibility.

Common examples include:

Speeding
Running a red light
Failing to yield
Following too closely
Making an unsafe lane change
Distracted driving
Driving under the influence
Ignoring traffic signs
Making an unsafe turn

A traffic citation can support your position, but it does not necessarily resolve every question about fault.

You should consider the entire sequence of events. Even when another driver violated a traffic law, evidence may show that additional factors contributed to the accident.

How Insurance Companies Determine Fault

After your accident, you may need to communicate with one or more insurance companies. An insurer will generally investigate the circumstances and decide how it believes responsibility should be allocated.

The investigation may include:

Police reports
Statements from drivers
Witness information
Photographs
Medical records
Vehicle damage
Video footage
Accident-related documents

You should remember that an insurance company's decision is not necessarily the final determination of legal fault.

If an insurer claims you caused the accident or assigns you a percentage of responsibility that you believe is inaccurate, you may need evidence to challenge that position.

You should also avoid guessing about facts you do not know. Statements made immediately after an accident can sometimes be misunderstood or used to dispute your claim.

What Happens When Both Drivers Are at Fault?

Some California accidents involve shared responsibility.

For example, imagine another driver was speeding while you were changing lanes. If both actions contributed to the crash, each driver could potentially be assigned a percentage of responsibility.

Under California's comparative negligence rules, your compensation may be reduced according to your percentage of fault.

This makes documentation particularly important. You should preserve evidence showing not only what the other driver did, but also the circumstances surrounding your own actions.

What Should You Do After a California Car Accident?

Your actions after a collision can help preserve evidence and protect your legal interests.

1. Move to Safety

If possible and safe, move away from active traffic. Call emergency services when necessary and avoid putting yourself in danger while documenting the scene.

2. Check for Injuries

Check yourself and others for injuries. If you are hurt or experience symptoms after the collision, seek appropriate medical attention.

Do not assume that you are uninjured simply because you feel fine immediately after the crash.

3. Photograph the Accident Scene

Take photographs of the vehicles, road, traffic signs, signals, debris, visible injuries, and other relevant conditions when it is safe.

4. Exchange Information

Obtain the other driver's identifying, vehicle, and insurance information. You should also provide your information as required.

5. Identify Witnesses

If people witnessed the collision, ask for their names and contact information if it is safe and practical to do so.

6. Report the Accident When Required

Depending on the circumstances, you may have legal obligations to report the accident. You should understand the applicable reporting requirements rather than assuming another person will handle them.

7. Preserve Your Records

Keep your photographs, videos, medical records, repair bills, insurance correspondence, witness information, and other accident-related documents in one location.

8. Be Careful With Insurance Statements

You should cooperate with legitimate insurance investigations, but you should avoid speculating about fault or minimizing your injuries.

If you do not know an answer, it is better to say that you do not know than to guess.

Why You Should Act Quickly

Evidence can become more difficult to obtain as time passes. Witnesses may forget important details, surveillance footage may be overwritten, vehicles may be repaired, and documents may become harder to locate.

For this reason, you should begin documenting your accident as soon as reasonably possible.

You should also be aware that California law establishes deadlines for pursuing certain legal claims. The applicable deadline can depend on the type of claim and circumstances involved. Waiting too long may affect your legal options.

How Fault Can Affect Your Compensation

The percentage of fault assigned to you can affect the amount you may recover.

Depending on the circumstances, recoverable damages may include medical expenses, lost income, property damage, and other losses recognized under California law.

For example, if you are awarded $75,000 in damages but are determined to be 10% responsible, your recovery could potentially be reduced by 10%.

The actual value of your claim depends on the evidence, severity of your injuries, financial losses, liability issues, insurance coverage, and other circumstances.

Common Mistakes That Can Complicate Fault Determination

You can make the process more difficult if you:

Admit fault at the accident scene without knowing all the facts.
Fail to photograph the vehicles or accident location.
Forget to collect witness information.
Delay medical evaluation despite experiencing symptoms.
Post statements or photographs about the accident on social media.
Give inaccurate or speculative information to an insurer.
Throw away accident-related documents.
Accept a settlement before understanding your losses.

You should focus on documenting facts and preserving evidence rather than trying to determine the entire legal case at the accident scene.
