Evidence After a Car Accident: Police Reports and Dashcam Video
By @damiennuxl250
The evidence in a car crash claim starts to scatter within hours. Cars are towed and repaired, video gets recorded over and witnesses become hard to reach. An auto accident lawyer usually looks first at the police https://rafaelphnj532.focalledger.com/posts/uninsured-motorist-pip-and-medpay-coverage-after-a-car-crash report, photos, video and the data stored in the vehicles. Here is how each source fits into a claim.
What the police report contains
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, 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. An auto accident attorney will compare the report with the photos and statements.
Photos and dashcam footage
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. 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, 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 others may access it only in limited situations, such as with the owner's consent or a court order.
EDR data can be lost if the car is repaired or crushed. 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 can be 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. This article is general information, not legal advice, and no result can be predicted from it.
