What to Do After a Rear-End Accident: Step-by-Step Guide
The decisions you make in the first 48 hours after a rear-end collision directly affect both your health and the value of any legal claim. Follow these 10 steps.
Rear-end collisions are the most common type of car accident in California — and the steps you take in the minutes, hours, and days after the crash directly affect both your health and the value of any legal claim. Follow these steps in order.
Check for injuries and call 911
Check yourself and all passengers for pain, numbness, or disorientation. Call 911 immediately — even if injuries seem minor. A police report documenting the rear-end collision is one of the most important pieces of evidence in your claim. Do not skip this step because the damage looks minor.
Stay at the scene — and stay calm
Do not leave the scene of the accident. Move vehicles out of traffic if it is safe to do so. Do not apologize, admit fault, or speculate about what happened — even casually. Anything you say at the scene can be used against you later.
Exchange information with the other driver
Get the following from the at-fault driver: full name and contact information, driver's license number, vehicle make, model, and license plate, insurance company name and policy number. Also note the responding officer's name and badge number, and ask for the police report number.
Document everything at the scene
Use your phone to photograph both vehicles from multiple angles, the road conditions, any skid marks, the positions of both vehicles, traffic signals or signs, and any visible injuries. Get the names and contact information of any witnesses — bystanders who saw the collision can be critical if liability is later disputed.
Seek medical attention within 24–48 hours — even if you feel fine
This is the single most important step after leaving the scene. Whiplash and soft tissue injuries are medically documented to produce peak symptoms 24 to 72 hours after impact — not at the scene. Adrenaline suppresses pain. If you do not seek treatment promptly, insurance companies will argue that you were not seriously injured.
Tell your doctor everything. Describe every area of pain, stiffness, numbness, or tingling — including symptoms that feel minor. Your medical record from this visit becomes the foundation of your claim. Gaps in treatment or vague initial complaints are the primary tools insurers use to minimize payouts.
Notify your own insurance company
Report the accident to your own insurer as required by your policy. Provide basic factual information about the accident. Do not volunteer opinions about fault or describe your injuries in detail at this stage.
Do not give a recorded statement to the other driver's insurer
The at-fault driver's insurance company — whether it is Geico, State Farm, Progressive, or any other carrier — will likely call you within 24 to 72 hours. As a third-party claimant you are not obligated to give them a recorded statement. Recorded statements taken before you know the full extent of your injuries are routinely used to minimize claims.
What to say: "I am in the process of consulting an attorney and will have my attorney contact you. I am not prepared to give a recorded statement at this time." That is a complete and legally appropriate response.
Preserve your vehicle — do not repair it yet
Do not authorize repairs to your vehicle until it has been photographed and documented. Vehicle damage is physical evidence. Your attorney may need it inspected before it is altered. Photograph all damage thoroughly before any repairs begin.
Keep a daily pain journal
Starting the day after the accident, write down your symptoms each day — pain levels, areas of discomfort, limitations on your ability to work or carry out daily activities, sleep disruption, and emotional impact. A consistent pain journal is powerful evidence of the ongoing effect of your injuries.
Consult a personal injury attorney before accepting any settlement offer
Insurance companies often make early settlement offers — sometimes within days of the accident — before the full extent of your injuries is known. Once you accept a settlement and sign a release, that is final. There is no recourse if your injuries prove more serious. Eagan Law offers free consultations and handles rear-end accident claims on a contingency fee basis — no fee unless a recovery is made. See our full guide to rear-end collision claims in California.
Statute of Limitations: California personal injury claims are generally subject to a two-year statute of limitations under CCP § 335.1. Claims against a government entity require a tort claim within six months. If the accident occurred in the course of employment, workers' compensation deadlines are shorter — notify your employer within 30 days. Eagan Law does not handle workers' compensation matters. Consult an attorney immediately.
Frequently Asked Questions
Yes. Whiplash and soft tissue injuries are medically documented to peak 24 to 72 hours after a rear-end collision — not at the scene. If you do not seek treatment promptly, insurers will argue you were not injured. A same-day or next-day medical visit protects both your health and your legal claim. See our detailed guide to whiplash and soft tissue injuries after a rear-end collision.
Do not give a recorded statement before consulting an attorney. Tell them you are consulting legal counsel and will be in touch. See our guide on what to know when an insurer calls after a rear-end accident.
The steps are the same regardless of carrier. See our guide to what to do when the driver who hit you has Geico insurance for carrier-specific guidance.
Low vehicle damage does not mean low injury. California courts have consistently recognized that low-speed impacts can cause significant soft tissue injuries to unbraced occupants. The "low-impact defense" used by insurers has been successfully challenged with biomechanical expert testimony. Do not assume you have no claim because your car looks fine.
