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 harder to find. A car accident attorney typically starts with the police report, photos, video and 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, sometimes called a police report. It typically lists the drivers and vehicles involved, with insurance details for each, and it often includes a diagram, a short narrative and any citations. 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.
A crash report is influential in insurance claims, 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 accident lawyer will check the report against the photos and statements.
Video and photo evidence
Dashcam footage can capture the seconds 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 event data recorder
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, 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. Insurers often move a total loss vehicle to a salvage auction quickly, so an automobile accident attorney may send a preservation letter asking that the vehicle be held until the data is 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.
