What to Do After a Car Accident: A Complete Accident Checklist
Car accidents happen every day on California roads—from busy freeways like I‑5 and Highway 99 to neighborhood streets and parking lots. Knowing what to do after a car accident in California can help protect your health, your legal rights, and your insurance claim.
This California car accident checklist outlines the essential steps drivers should take immediately after an auto accident anywhere in the state.
Step 1: Check for Injuries and Call 911
Your safety comes first after any car accident. Check yourself, your passengers, and others involved for injuries. If anyone is hurt, call 911 right away and request medical assistance.
Under California law, accidents involving injury or death must be reported, and prompt medical attention can also help document injuries for insurance or legal purposes.
Step 2: Call the Police and Stay at the Scene
In California, you should contact local law enforcement after an accident—especially if there are injuries, significant damage, or disputes about fault. A police report can be critical when filing an auto insurance claim or pursuing a legal case.
Remain at the scene until police arrive unless it is unsafe to stay.
Step 3: Make the Scene Safe
Turn on your hazard lights to alert other drivers. If available and safe to use, set out flares or warning triangles to help prevent secondary accidents—especially on highways or busy roads.
Step 4: Stay Calm and Do Not Admit Fault
California is a comparative fault state, meaning liability can be shared. Avoid admitting fault, apologizing, or speculating about what caused the accident. Let insurance companies and, if necessary, legal professionals determine responsibility.
Step 5: Exchange Information as Required in California
California drivers are required to exchange certain information after an accident. Be sure to collect and share:
- Full names
- Addresses, email addresses, and phone numbers
- Driver’s license numbers
- Vehicle license plate numbers
- Vehicle make and model
- Auto insurance company names and policy numbers
This information is essential for complying with California insurance requirements and filing a claim.
Step 6: Gather Witness and Passenger Information
If there are passengers or witnesses, ask for their names and contact details. Independent witnesses can be especially helpful if fault is disputed or if the accident occurred in heavy traffic or a busy intersection.
Step 7: Document the Accident Scene
If possible, sketch the accident scene or make notes about:
- Vehicle positions
- Directions of travel
- Traffic signals or stop signs
- Road and weather conditions
This documentation can support your insurance claim or legal case later.
Step 8: Record Vehicle and Property Damage
Carefully inspect and note damage to all vehicles involved, as well as any surrounding property such as guardrails, signs, or fences. California insurance claims often rely heavily on detailed documentation.
Step 9: Take Photos at the Scene
Photos can provide powerful evidence after a car accident in California. Use your phone to take pictures of:
- The accident scene from multiple angles
- Damage to all vehicles
- License plates
- Driver’s licenses
- Insurance cards
Take photos before vehicles are moved, if it’s safe to do so.
Step 10: Limit What You Say or Sign
Do not discuss the accident with anyone other than law enforcement or your insurance company. Avoid signing documents at the scene unless instructed by police.
Step 11: Report the Accident to Your Insurance Company
Contact your auto insurance company or agent as soon as possible after the accident. California insurers typically require prompt notice, even if you were not at fault.
Provide accurate details and submit photos, notes, and the police report when available.
