What to do after a car crash in California

1. The first few hours after a car accident can significantly affect both your health and your personal injury claim.
Taking immediate steps such as seeking medical attention, documenting the accident scene, gathering witness information, and preserving evidence can strengthen your case and help protect your legal rights.

2. Small mistakes after a collision can have lasting consequences.
Delaying medical treatment, failing to document the scene, or speaking with insurance companies before understanding your legal options may make it more difficult to recover the compensation you deserve.

3. Every California car accident is different, but having experienced legal guidance early can make a meaningful difference.
An attorney can help preserve critical evidence, communicate with insurance companies, explain your legal rights, and guide you through the claims process while you focus on your recovery.

No two car accidents are exactly alike. Every collision presents its own unique facts, injuries, insurance issues, and legal considerations. For that reason, there is no single answer that applies to every personal injury case.

There are, however, important steps that nearly every accident victim should consider in the minutes, hours, and days following a car accident, truck accident, motorcycle accident, pedestrian accident, or another serious incident. Understanding the risks of common post-crash mistakes and conflicting advice before it ruins your claim is the first step toward protecting your recovery. 

The actions you take immediately after an accident can affect your physical recovery, the evidence available to support your claim, the insurance company’s investigation, and ultimately your ability to recover fair compensation. While every situation is different, understanding what to do, and what to avoid, can help protect both your health and your legal rights.

Below are several practical steps that Senior Trial Attorney Anson Bui recommends following after a car accident.

The First Hours after an Accident Can Be Critical

The moments immediately following a collision are often chaotic. It is understandable to feel overwhelmed or uncertain about what to do next. However, many of the decisions made during this time—from documenting the accident scene to seeking medical attention—may become important later if an insurance claim or lawsuit arises.

The Core Principle: Although every case is unique, one principle remains the same: the actions you take immediately following an accident may have lasting consequences for both your health and your personal injury claim.

Approaching the situation methodically can help preserve important evidence and protect your legal rights. When the unexpected happens on California roads, keep these strategic steps in mind.

7 Critical Steps to Protect Your Rights After a California Accident 

Steps To Protect Your Rights After A California Accident	Timeline	Additional Information
Prioritize Safety and Medical Checkpoints	Minutes 1–15	The absolute first priority after any collision is establishing physical safety before addressing legal or insurance considerations: Check for Injuries: Assess yourself and your passengers immediately. If anyone exhibits signs of distress or trauma, call 911 without delay. Move to a Secure Location: If the vehicle is operable and it is safe to do so, move completely to the shoulder of a California freeway or near the curb of a surface street. Trial Attorney Insight: Under California Vehicle Code § 20002(a), drivers are legally required to clear active traffic lanes if an accident involves only property damage and the vehicle is operable.  The statute explicitly protects your legal rights, stating that “moving the vehicle in accordance with this subdivision does not affect the question of fault.”  Protecting lives always comes before preserving a scene.  Doing so protects lives and complies with the law—it will never hurt your legal claim.
Document the Scene and Preserve Volatile Evidence	Minutes 15–30	Accident scenes change rapidly as vehicles are towed and debris is cleared. Capture the physical facts before they disappear: The Vehicles: Take clear photos of your vehicle and the adverse vehicle, documenting the exact point of impact and the severity of property damage. The Roadway: Document skid marks, broken glass, scattered debris, and the layout of traffic signals or signs. Unmoved Positions: In low-speed or parking lot accidents, take photographs before moving the vehicles to help accident reconstruction experts establish the exact mechanics of the collision.
Secure Independent Witness Verification	Minutes 15–30	Unbiased, third-party testimony carries immense weight with insurance adjusters and juries. Identify Eyewitnesses: If a bystander or trailing driver stopped to help, ask for their name and phone number before they leave. Mitigate Liability Disputes: Independent witnesses have no financial stake in your recovery, making their statements the ultimate defense if the other driver later changes their story or denies fault.
Exchange Information Methodically	Minutes 30-45	Interact with the other driver with a focus entirely on objective fact-gathering. Remain polite and brief—avoid discussing fault, arguing, or apologizing, as simple expressions of regret can be twisted by insurers as admissions of liability. Under California Vehicle Code § 16025, every driver involved in an accident is legally required to exchange specific information at the scene (unless rendered physically incapable).  California Vehicle Code § 16025: (a) Every driver involved in the accident shall, unless rendered incapable, exchange with any other driver or property owner involved in the accident and present at the scene, all of the following information: (1) Driver’s name and current residence address, driver’s license number, vehicle identification number, and current residence address of registered owner. (2) Evidence of financial responsibility, as specified in Section 16020. If the financial responsibility of a person is a form of insurance, then that person shall supply the name and address of the insurance company and the number of the insurance policy. (b) Any person failing to comply with all of the requirements of this section is guilty of an infraction punishable by a fine not to exceed two hundred fifty dollars ($250). In other words: You cannot simply swap phone numbers and leave. Unless you are physically unable due to injury, California law requires a complete exchange of names, home addresses, driver’s licenses, insurance policy numbers, and even the Vehicle Identification Number (VIN). If the driver doesn’t own the car, you must get the registered owner’s address too. Refusing to hand this over isn’t just unhelpful—it is a legal infraction punishable by a fine of up to $250.
Request Law Enforcement to Establish an Official Record	Minutes 30–60	Contact local law enforcement (CHP or local police) to dispatch an officer to the scene if there are injuries, significant property damage, or an immediate dispute over fault. The Police Report: While a police report usually cannot be used as direct evidence in a California courtroom trial, adjusters rely on it when deciding who was at fault during early settlement talks.
Seek Prompt Medical Evaluation	Within 24 Hours	Adrenaline and shock routinely mask severe musculoskeletal pain, whiplash, soft-tissue damage, or internal trauma. Eliminate “Gaps in Treatment”: Seeking a prompt evaluation from a medical professional protects your physical health and establishes a clean, chronological timeline. Defeat Insurer Denials: Delaying medical care gives insurance companies a legal opening to claim your injuries were caused by an unrelated event or are not as severe as documented.
Contact Cohn & Swartzon LLP	Days 1–3	Before giving a recorded statement to an insurance adjuster, speak with an attorney at Cohn & Swartzon LLP.
