It happens fast. One moment you’re on the 405 or the 10, the next there’s impact, the smell of deployed airbags, and a strange stillness that follows the chaos. What you do in those first minutes and hours matters far more than most drivers realize — not just for your safety, but for any insurance claim or legal action that comes after.
California sees roughly 200,000 injury crashes every year. Here’s what to do if you’re in one.
Step 1: Prioritize Safety at the Scene
If your car is drivable and you can safely move it out of traffic, do so. Turn on your hazard lights. If anyone appears seriously injured, call 911 immediately and do not move them unless there is an imminent danger, oncoming traffic, fire that makes staying in place more dangerous than moving.
Once the immediate safety picture is under control, call the police. California law requires you to report any accident involving injury, death, or property damage over $1,000. Even in minor crashes, a police report creates an official, time-stamped record that both insurers and attorneys will rely on later. Do not let the other driver talk you out of filing one. “Let’s just handle this between us” is almost never in your interest.
Step 2: Document Everything Before Anyone Moves
Before any vehicle is moved, photograph the scene from multiple angles. Take wide shots showing both vehicles’ positions relative to the road, close-ups of all damage on both vehicles, and shots of the surrounding context, skid marks, road conditions, traffic signals, weather. Screenshot your phone’s clock, weather app, and GPS location. These details feel trivial in the moment. They become critical weeks later when memories have faded and the other driver’s account has shifted.
Photograph the other driver’s license and insurance card rather than copying the information by hand. Get the names and contact information of any bystanders before they leave, witnesses have a way of disappearing within minutes.
Step 3: Watch What You Say
Do not apologize. Do not say “I didn’t see you” or “I should have braked sooner.” These are natural human responses to a stressful moment, but in California, any statement suggesting fault can be used against you in a claim or lawsuit. Stick to facts when speaking to the other driver, witnesses, and police: what happened, where, when. Let the investigation determine fault — that’s its job.
This applies to social media as well. Do not post anything about the accident until the matter is fully resolved.
Step 4: Get Medical Attention the Same Day
Go to urgent care or your primary care physician even if you feel fine. Adrenaline is a powerful pain mask. Whiplash, soft tissue injuries, and concussions frequently do not present symptoms for 24 to 72 hours. If you wait until symptoms appear to seek treatment, an insurer will argue that your injuries predated the accident, were not serious, or resulted from something else entirely.
The medical record created on the day of the accident is one of the most important documents in any injury claim. Do not skip this step.
Step 5: Notify Your Insurance Company
California insurers generally require prompt notification of accidents. Review your policy, many specify a reporting window. When you call, give your insurer the same factual account you gave the police. Do not speculate about fault, minimize injuries, or make promises about what treatment you will seek. Your initial statement is on record.
Step 6: Know When to Call an Attorney
If the accident involved any injuries to you, your passengers, or anyone else, or significant property damage, consult a California car accident attorney before you give a recorded statement to the other driver’s insurer or accept any settlement offer.
This matters more than most people expect. Insurers are motivated to close claims quickly and for as little as possible. They are skilled at it. An attorney who handles these cases regularly can assess what your claim is worth and whether the offer on the table reflects that reality. Most California personal injury attorneys work on contingency: no upfront fees, no costs to you unless they recover compensation on your behalf.
A phone call costs nothing and can clarify your position before you commit to anything.
The 24-Hour Window Is the Foundation
The first 24 hours after an accident set the foundation for everything that follows — the insurance claim, potential litigation, and your own recovery. Evidence disappears. Witness memories fade. Surveillance footage gets overwritten. Injuries that seem manageable in the immediate aftermath sometimes turn out to be significant.
The drivers who navigate this best are the ones who document thoroughly, speak carefully, get medical attention that same day, and understand their rights before signing anything. California’s roads are some of the busiest in the country. Knowing these steps before you need them is one of the more practical things any driver can do.
