Evidence After a Car Crash: Police Reports and Dashcam Video
The evidence in a car crash claim starts to scatter within hours. Vehicles get towed and repaired, video is overwritten and witnesses become hard to reach. An auto accident lawyer usually looks first at the police report, photos, video and the data stored in the vehicles. This article explains 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 usually records who was driving each vehicle and which insurer covers it, and it often includes a diagram, a short narrative and any citations. Many states also require drivers to report crashes Learn here 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, sometimes for a fee.
A crash report is influential in insurance claims, but it is not the final word on fault. car accident lawyer Rules on using an officer's opinions at trial vary by state. If the report contains a factual error, such as a wrong plate number, the agency may accept a request for a correction or a supplement. A car crash 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. Keep the original file with its timestamp, instead of a phone recording of the screen, and make a backup copy. Traffic cameras and nearby businesses may also have recorded the crash, but many systems overwrite footage within days or weeks. Photos taken at the scene show vehicle positions, debris, skid marks and road signs, while photos of injuries taken over several weeks can document healing.
The car's own black box
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 period, measured in seconds, not minutes, around the time of 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 a motor vehicle accident lawyer may send a preservation letter asking that the vehicle be held 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 insurers often point to gaps in treatment 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. A short journal of pain levels and missed work, written while the details are fresh, can also help.
