What to Do Immediately After a Car Accident in San Francisco

A car accident in San Francisco can happen in an instant — a sudden stop on Van Ness, a blind turn in the Sunset, a rear-end collision crossing the Bay Bridge. But what you do in the minutes, hours, and days afterward can shape your recovery for months or years to come. The right steps protect your health, strengthen your legal claim, and keep insurance companies from taking advantage of you when you’re at your most vulnerable.

Below, the attorneys at Tien Law Firm walk you through exactly what to do after a car accident in San Francisco, the California laws that affect your case, and how our San Francisco office helps injured drivers throughout the city and the greater Bay Area recover full and fair compensation.

1. Check for Injuries and Call 911

Your safety comes first, always.

• Check yourself and your passengers for injuries before doing anything else.
• Call 911 immediately. San Francisco Police Department (SFPD) response is required for any accident involving injury, death, or significant property damage, and the resulting police report becomes critical evidence for your claim.
• If your vehicle is drivable and it’s safe to do so, move it out of active traffic lanes. Never move a seriously injured person unless there’s immediate danger, like fire or oncoming traffic.

Adrenaline often masks pain. Whiplash, concussions, and soft-tissue injuries frequently don’t surface until hours or even days later — another reason to get evaluated even if you feel okay at the scene.

2. Document Everything at the Scene

San Francisco’s dense streets, frequent construction zones, and heavy pedestrian and cyclist traffic make thorough documentation especially important. While you wait for police:

• Photograph and video all vehicles involved, license plates, visible injuries, the road surface, traffic signals or signs, and the surrounding area.
• Exchange information — name, phone number, insurance details, and license plate — with every driver involved.
• Get witness contact information. San Francisco’s foot and bike traffic means there’s often someone nearby who saw exactly what happened.
• Note the precise location, including cross streets, nearby landmarks, and the time of day.
• Get the police report number before leaving, or ask the responding officer how to obtain a copy.

This evidence has a short shelf life. Traffic and business surveillance footage gets overwritten within days, and witnesses become harder to reach the longer you wait.

3. Don’t Admit Fault or Give a Recorded Statement

It’s instinctive to say “I’m sorry” or try to explain what happened — but avoid it. California follows a comparative negligence rule, meaning your compensation can be reduced by whatever percentage of fault is assigned to you. Casual statements at the scene can be twisted later to shift blame your way.

Be especially cautious with the other driver’s insurance company. Adjusters often call within 24–48 hours asking for a recorded statement. You are not required to give one, and it’s rarely in your interest to do so without an attorney. Tien Law Firm can communicate with insurers on your behalf so nothing you say is used against you.

4. Get Medical Attention Right Away

Even if you refuse transport by ambulance, see a doctor or visit urgent care within 24–48 hours of the accident. This matters for two reasons:

1. It protects your health. Some injuries — traumatic brain injuries, internal bleeding, spinal damage — aren’t obvious right away.
2. It creates a documented link between the accident and your injuries. Insurance companies look closely for gaps in treatment, and they routinely use those gaps as an excuse to deny or undervalue claims.

Follow through on every recommended treatment, referral, and physical therapy session. Stopping early, even if you’re feeling better, can weaken your case.

5. Notify Your Insurance Company

California law requires you to report the accident to your own insurer, but keep the conversation factual: date, time, location, and vehicles involved. Don’t speculate about fault, and don’t downplay your injuries (“I’m probably fine”) — even to your own insurance company.

6. Keep Detailed Records

Start building a file — physical or digital — with:

• The police report
• Photos and video from the scene
• All medical records and billing statements
• Vehicle repair estimates and damage photos
• Proof of missed work or lost income
• A personal journal tracking pain levels and how the injury has affected your daily life

This documentation is often the difference between a lowball settlement offer and one that reflects the true cost of what you’ve been through — including harder-to-calculate damages like future medical care and lost earning capacity.

7. Talk to a San Francisco Car Accident Attorney Before You Settle

Insurance adjusters are trained to close claims quickly and for as little as possible. An early settlement offer can look appealing when medical bills are piling up, but accepting it usually means giving up your right to pursue further compensation — even if your injuries turn out to be more serious than initially thought.

California’s statute of limitations for personal injury claims is generally two years from the date of the accident (Cal. Civ. Proc. Code § 335.1). If a government vehicle was involved — a Muni bus, a city or county vehicle — you may have as little as six months to file a claim. Missing these deadlines can permanently forfeit your right to compensation.

A San Francisco car accident lawyer can:

• Investigate the crash and gather evidence you may not have access to
• Handle every conversation with insurance adjusters
• Calculate the full value of your claim, including future medical needs
• Negotiate aggressively, and litigate if necessary, to maximize your recovery
• Make sure no deadline slips by while you focus on healing
