A rear-end crash at a red light often looks simple from the driver’s seat. You were stopped, another vehicle hit you, and the damage should speak for itself. The claim can become less simple once the vehicles are moved and an adjuster starts asking about the light sequence, the force of impact, and when the first symptoms appeared.
The best response is a clear record of what actually happened. You do not need to turn yourself into an accident investigator. You do need to preserve the things that may disappear and avoid guessing about details you do not know.
Start with the scene, not a theory
If it is safe, photograph the resting positions of the vehicles before they are moved. Take wide photographs that show the traffic signal, stop line, lanes, nearby businesses, and the full intersection. Then take closer photographs of both vehicles, visible damage, debris, and license plates.
Get the names and telephone numbers of witnesses. Note which law-enforcement agency responded and keep the report number. If a business, home, or another vehicle may have recorded the crash, write down its location. Video is often overwritten long before an insurance dispute develops.
When Louisiana State Police handles a crash, its Traffic Records Unit explains how reports can be obtained. A crash report is useful, but photographs, witnesses, repair records, and video may answer questions the report does not.
Write down the sequence while it is still fresh
A short factual note is more useful than a dramatic retelling. Record where you were stopped, whether the light had changed, whether the impact pushed your vehicle forward, and whether another vehicle was involved. Do not estimate speed unless you actually know it. Do not fill in a gap just because an insurer asks for an immediate answer.
Keep the claim number, adjuster’s name, and dates of important conversations in the same place. If the insurer asks for a recorded statement or a broad medical authorization, understand the request before agreeing. Our guide to insurance negotiations after a Louisiana injury explains why the wording and timing of those communications matter.
Preserve the vehicle before the evidence changes
Exterior bumper photographs do not always show every damaged component. Keep the first estimate, later supplements, towing and storage records, rental paperwork, and photographs taken during disassembly. If the vehicle may be totaled or repaired quickly, ask before authorizing disposal of damaged parts that could matter to the claim.
Some vehicles contain an event data recorder. NHTSA describes an EDR as a device or function that records information related to a crash. Whether useful data exists depends on the vehicle, the event, and the issues in dispute. It should not be assumed that every vehicle recorded every fact.
Describe symptoms accurately
People do not always notice every symptom at the scene. Adrenaline, noise, and concern for passengers can distract from pain or confusion. If symptoms develop or worsen, tell the treating provider when they began and how they affect ordinary activities such as sleeping, driving, lifting, or working.
A short daily note can help you remember significant changes. It should be honest and balanced. Record improvement as well as difficulty. Medical records, diagnostic testing, and the provider’s opinions carry more weight than an attempt to diagnose yourself from the internet.
Different injuries require different evaluation. For example, our Louisiana shoulder-injury guide discusses the distinction between symptoms, diagnosis, and functional limits after a crash.
What the insurer may dispute
An insurer may argue that the first driver stopped suddenly, the collision caused little damage, a medical visit came too late, or the symptoms came from an earlier condition. None of those points should be answered with a slogan. They should be tested against the traffic sequence, witness accounts, repair file, medical history, and treating records.
A prior condition does not automatically end a claim, but it makes accuracy especially important. Give providers a truthful history and distinguish what existed before the crash from what changed afterward. Avoid discussing the claim on social media. Even an ordinary photograph can be taken out of context, as explained in our guide to social media and Louisiana injury claims.
Louisiana deadlines and fault rules
Louisiana Civil Code article 3493.1 establishes a general two-year prescriptive period for delictual actions and states when that period begins. The article became effective July 1, 2024. Earlier crashes, claims against government entities, and other special circumstances may require a different analysis, so the incident date and defendant matter.
For incidents governed by the rule effective January 1, 2026, Civil Code article 2323 bars recovery when the injured person’s assigned negligence is 51 percent or greater and reduces damages proportionally when it is below that threshold. A rear impact does not eliminate the need to preserve evidence about the entire sequence.
When to get help quickly
Prompt legal advice can be especially important when video may exist, a commercial or government vehicle was involved, the vehicle is about to be repaired or destroyed, the collision involved several impacts, or the insurer is pressing for a statement or release before the medical picture is clear.
Our rear-end collision practice page explains how these cases are investigated. Call (225) 500-5000 if you need help preserving evidence or evaluating an insurance request.
