Police Reports, Dashcam Video and Car Crash Evidence
By @jeffreyhaae289
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. An auto accident lawyer usually looks first at the police report and any photos or video, then 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, 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. In many states, drivers must also report crashes involving injury, death or property damage above a set dollar amount. Copies usually come from the responding agency, such as 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. 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 check the report against the photos and statements.
Video and photo evidence
Dashcam video can show the moments 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. Traffic cameras and nearby businesses may also have recorded the crash, though many systems record over 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.
The event data recorder
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, 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 if the car is repaired or crushed. Total loss vehicles are often moved to salvage auctions within weeks, so https://trevorbcxu211.nexorafield.com/posts/police-reports-dashcam-video-and-car-crash-evidence a car accident attorney 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. Their names and phone numbers should be collected at the scene if it is safe to do so. Medical records link the injuries to the crash, and insurers often point to gaps in treatment to dispute a claim. Keeping the claim number in one place, with a log of each call to 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 article is general information, not legal advice, and no result can be predicted from it.
