What to Do After a Car Accident in California: Step-by-Step

A car accident can leave you dealing with injuries, vehicle damage, insurance questions, and deadlines that begin almost immediately. Taking the right steps at the scene helps protect your health, preserves important evidence, and can make the insurance claims process much smoother.

If you're reviewing your coverage after an accident or simply want to make sure you're protected before one happens, take a look at our Auto Insurance options. An independent TSM Insurance advisor can help you compare coverage and identify gaps before they become expensive claims.

The steps below explain what California drivers should do immediately after a collision, when state law requires reporting an accident, how comparative fault affects insurance claims, and when legal guidance may become necessary.

Stop and Check for Injuries (California Vehicle Code §20001)

California law requires every driver involved in an accident to stop immediately. Leaving the scene after an accident involving injury or death can result in serious criminal penalties under California Vehicle Code §20001. Even when a collision appears minor, drivers must stop, remain at the scene, and determine whether anyone needs medical attention.

Your first priority should always be safety. Check yourself, your passengers, and the occupants of the other vehicle for injuries before focusing on vehicle damage or insurance information. If someone appears seriously injured, avoid moving them unless remaining in the vehicle creates an immediate danger, such as fire or oncoming traffic.

If the vehicles can be moved safely, relocate them to the shoulder or another safe location to reduce the risk of another collision. Turn on your hazard lights and remain alert to surrounding traffic while waiting for emergency responders.

Adrenaline often masks pain after an accident. Neck injuries, back injuries, and concussions may not become obvious until hours later. Seeking medical evaluation promptly creates a clear record of your injuries while ensuring you receive appropriate treatment as soon as possible.

Call 911 and Report the Accident

After checking for injuries, contact emergency services if anyone has been hurt, if the roadway is blocked, or if the accident involves significant property damage.

A responding law enforcement officer will document the scene, speak with drivers and witnesses, and prepare an official accident report. That report often becomes valuable evidence during the insurance claims process, especially if liability is disputed later.

Remain calm while speaking with the responding officer and answer questions honestly. Stick to the facts about what happened without speculating about fault or making assumptions about the other driver's actions. The investigation will determine how the collision occurred based on the available evidence.

Even if another driver suggests handling everything privately without involving law enforcement, reporting the accident is usually the safest decision. Injuries and vehicle damage frequently become more apparent after everyone leaves the scene, and having official documentation can prevent disagreements later.

Some accidents may also require reporting to the California Department of Motor Vehicles, which is discussed later in this article.

Exchange Information With Other Drivers

California drivers should exchange information before leaving the accident scene. Collecting complete and accurate details helps your insurance company investigate the claim efficiently and reduces delays during the repair process.

Be sure to exchange:

• Full name and contact information

• Driver's license number

• Insurance company and policy number

• Vehicle registration information

• License plate number

• Vehicle make, model, and year

Take time to verify the information rather than relying solely on handwritten notes. Photograph insurance cards, driver's licenses when permitted, vehicle registrations, and license plates to reduce the chance of transcription errors.

Keep the conversation respectful and focused on exchanging information. Avoid discussing fault, apologizing, or making statements about who caused the accident. Insurance companies determine liability after reviewing all available evidence, including photographs, witness statements, police reports, and applicable California traffic laws.

Do not accept cash at the scene in exchange for avoiding an insurance claim. Damage that appears minor immediately after a collision can become substantially more expensive once repairs begin, particularly when hidden structural damage is discovered.

Document the Scene

Once everyone is safe and information has been exchanged, begin documenting the accident while the vehicles are still in their original positions, if it is safe to do so. The more evidence you collect immediately after the collision, the easier it becomes to support your version of events if questions arise during the insurance investigation.

Photographs are often some of the strongest evidence available after an accident. Capture wide-angle photos showing the entire scene before taking close-up images of vehicle damage. Include multiple angles of every vehicle involved, skid marks, traffic signals, lane markings, road signs, debris, weather conditions, and anything else that may have contributed to the collision.

If another driver admits responsibility at the scene, avoid relying on a verbal statement alone. Insurance companies evaluate claims using multiple sources of evidence, and statements made immediately after an accident may later be disputed. Physical evidence and official reports typically carry much more weight than conversations that cannot be verified.

Witnesses can also play an important role. If anyone saw the accident happen, politely ask for their name and phone number before they leave. Independent witnesses often provide valuable information when drivers have different accounts of how the collision occurred.

Finally, write down your own recollection while everything is still fresh. Record the time, location, direction each vehicle was traveling, traffic conditions, weather, and anything unusual you noticed immediately before the impact. Even small details can become important later.

Report the Accident to the California DMV

Reporting the accident to your insurance company is not always the same as reporting it to the California Department of Motor Vehicles.

California requires drivers to submit an SR-1 Report of Traffic Accident to the DMV within 10 days if the accident resulted in injury, death, or property damage exceeding $1,000. This requirement applies regardless of who caused the accident and even if law enforcement responded to the scene.

Failing to submit the required report can result in the suspension of your driving privileges until the reporting requirement has been satisfied.

The SR-1 form requests information such as:

• The date, time, and location of the accident.

• Driver and vehicle information.

• Insurance policy details.

• A description of injuries and property damage.

Submitting the SR-1 does not determine fault. It simply satisfies California's legal reporting requirement. Your insurance company can often answer questions about completing the form, but responsibility for filing it ultimately belongs to the driver.

Contact Your Insurance Company

Notify your insurance company as soon as reasonably possible after the accident. Most policies require prompt reporting, and delaying notification can complicate the claims process.

When speaking with your insurance representative, provide accurate information about the accident, explain what occurred, and share any documentation you collected at the scene. This may include photographs, witness information, the police report number, and contact information for the other driver.

Your claims representative may also ask for:

• Photos of vehicle damage.

• A copy of the police report when available.

• Medical documentation if injuries occurred.

• Repair estimates.

• Dash camera footage, if applicable.

If your vehicle cannot be driven safely, ask about towing coverage, rental car benefits, and the next steps for scheduling repairs. Depending on your policy, these coverages may already be included.

If your vehicle is declared a total loss during the claims process, our article What Happens When Your Car Is Totaled? explains how insurance companies determine vehicle value and what to expect during the settlement process.

If you're reviewing your coverage after the accident, this is also a good opportunity to compare your current protection with California's minimum insurance requirements. Our article Full Coverage vs. Minimum Auto Insurance explains the differences and why higher limits may provide better financial protection after a serious collision.

Understand California's Comparative Fault Law

California follows a pure comparative negligence system. That means more than one driver can share responsibility for an accident, and each person's compensation may be reduced based on their percentage of fault.

For example, imagine another driver runs a stop sign but you were driving above the speed limit. After investigating the accident, the insurance companies determine the other driver was 80% responsible and you were 20% responsible. If your total damages equal $20,000, you could still recover compensation, but it would be reduced by your share of fault.

Because fault directly affects claim payments, insurance companies carefully review every piece of available evidence. Police reports, photographs, witness statements, dash camera footage, vehicle damage, and even cell phone records may all be considered during the investigation.

Avoid assuming fault at the scene, even if you believe you could have done something differently. A simple apology or casual statement can later be interpreted as accepting responsibility before the facts have been reviewed. Stick to the facts when speaking with law enforcement, insurance adjusters, and the other driver.

If liability is disputed, continue documenting everything related to the accident, including repair estimates, medical records, correspondence with your insurance company, and any expenses resulting from the collision.

When to Hire an Attorney

Not every car accident requires legal representation. Minor collisions involving limited property damage and no injuries are often resolved directly through the insurance claims process.

An attorney may be worth considering if:

• You suffered significant injuries.

• Fault for the accident is disputed.

• Multiple vehicles were involved.

• The insurance company denies or delays your claim.

• Settlement offers do not cover your medical bills, lost income, or vehicle damage.

• A commercial vehicle or uninsured driver was involved.

An attorney can explain your legal options, negotiate with insurance companies, and protect your interests if the claim becomes more complicated than expected.

Even if you decide not to hire an attorney, keeping organized records throughout the claims process will make resolving your claim much easier.
