Evidence After a Car Accident: Police Reports and Dashcam Video
Presented by @franciscowmzw340
The evidence in a car crash claim starts to scatter within hours. Cars are 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 police report
When officers respond to a crash, they 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 https://caraccidentlawyers.wiki/reference/lost-income/ 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 are usually available from the agency that responded, whether that is 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. Rules on using an officer's opinions at trial vary by state. When a report has a factual error, such as a wrong plate number, the agency may accept a request to correct or supplement it. A car crash attorney will check the report against the photos and statements.
Video and photo evidence
Dashcam video can show the moments before a crash better than a witness can. Save the original file with its date and time stamp, rather than a phone recording of the screen, and make a backup copy. Traffic cameras and nearby businesses may also have recorded the crash, 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.
The car's own black box
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, measured in seconds, not minutes, surrounding a crash. Depending on the vehicle, the data may include speed and brake application as well as 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 an automobile accident attorney may send a preservation letter asking that the vehicle be held until the data is downloaded.
Witness statements 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.
