Evidence After a Car Accident: Police Reports and Dashcam Video
By @mariotdkt975
The evidence in a car crash claim starts to scatter within hours. https://gunnerzuez228.dovetailscope.com/posts/who-is-liable-in-a-car-crash Vehicles get towed and repaired, video gets recorded over and witnesses become harder to find. An auto accident lawyer 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.
The crash report
Officers who respond to a crash usually prepare a crash report, often called a police report. It typically lists the drivers and vehicles involved, with insurance details for each, 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, such as a city police department, a sheriff's office or the state highway patrol, sometimes for a fee.
Insurers rely heavily on the crash report, but it does not decide 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 check the report against the photos and statements.
Video and photo evidence
Dashcam footage can capture the seconds before a crash more clearly than any witness. Keep the original file with its timestamp, rather than a phone recording of the screen, and store a backup copy. Nearby businesses, buses and traffic cameras may have recorded the crash too, though many systems record over footage within days or weeks. Scene photos can show where the vehicles stopped and the debris and skid marks around them, and photos of injuries taken over several weeks can show how they changed.
What the vehicle itself recorded
Many cars and light trucks carry an event data recorder (EDR). NHTSA describes an EDR as a device that records technical vehicle and occupant information for a brief period, seconds rather than 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 access by others is limited to situations such as owner 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 motor vehicle accident lawyer may send a preservation letter asking that the vehicle be held until the data is downloaded.
Witnesses and medical records
Witnesses with no stake in the claim often carry weight. Collect their names and phone numbers at the scene when it is safe. Medical records connect 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.
