Police Reports, Dashcam Video and Car Crash Evidence
The evidence in a car crash claim starts to scatter within hours. Cars are towed and repaired, video is overwritten and witnesses become hard to reach. A car accident attorney usually looks first at the police report and any photos or video, then the data stored in the vehicles. Here is how each source fits into a claim.
What the police report contains
When officers respond to a crash, they usually prepare a crash report, sometimes called a police report. It usually records who was driving each vehicle and which insurer covers it, along with a diagram, a short narrative and any citations issued. Many states also require drivers to report crashes that involve injury, death or property damage above a set amount. Copies usually come from the responding agency, whether that is a city police department, a sheriff's office or the state highway patrol, often for a small fee.
A crash report is influential in insurance claims, but it is not the final word on fault. States differ on whether an officer's opinions can be used at trial. When a report has a factual error, such as a wrong plate number, the agency may accept a request to correct or supplement it. An auto accident attorney will compare the report with the photos and statements.
Dashcam video and photographs
Dashcam footage can capture the seconds before a crash more clearly than any witness. Save the original file with its date and time stamp, rather than a phone recording of the screen, and make a backup copy. Nearby businesses, buses and traffic cameras may have recorded the crash too, but many systems overwrite footage within days or weeks. Photos taken at the scene show vehicle positions, debris, skid marks and road signs, and photos of injuries taken over several weeks can show how they changed.
What the vehicle itself recorded
Many passenger vehicles have an event data recorder (EDR). NHTSA describes an EDR as a device that records technical vehicle and occupant information for a brief https://waylonkvcp837.lakeviewbrief.com/posts/how-crash-reports-and-dashcam-video-shape-an-auto-accident-claim-2 period, measured in seconds, not minutes, around the time of a crash. Depending on the vehicle, it may record speed and braking, along with seat belt use. NHTSA's rule in 49 CFR Part 563 sets requirements for EDRs in light vehicles that have them. Under the Driver Privacy Act of 2015, EDR data generally belongs to the vehicle owner or lessee, and others may access it only in limited situations, such as with the owner's consent or a court order.
EDR data can be lost when a car is repaired or sold for salvage. Total loss vehicles are often moved to salvage auctions within weeks, so a car accident attorney may send a preservation letter asking the insurer or tow yard to hold the vehicle until the data can be downloaded.
Witnesses and medical records
Independent witnesses carry weight because they have no stake in the claim. Collect their names and phone numbers at the scene when it is safe. Medical records link the injuries to the crash, and gaps in treatment are often used by insurers to dispute a claim. A simple file with the claim number and a log of every call with the adjuster makes later questions easier to answer. Pain levels, missed work and appointments are worth noting in a journal while the details are fresh. This is general information rather than legal advice, and it does not predict the result of any claim.
