Police Reports, Dashcam Video and Car Accident Evidence
The evidence in a car crash claim starts to scatter within hours. Vehicles get towed and repaired, video gets recorded over and witnesses become hard to reach. An auto accident lawyer 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 police 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. 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.
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. An auto accident attorney will compare the report with the photos and statements.
Photos and dashcam footage
Dashcam video can show the moments before a crash better than a witness can. Keep the original file with its timestamp, instead of a phone recording of the screen, and store a backup copy. Nearby businesses, buses and traffic cameras may have recorded the crash too, 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). https://griffinbgcb514.clarionvale.com/posts/how-to-choose-a-car-accident-attorney 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. Total loss vehicles are often moved to salvage auctions within weeks, so a motor vehicle accident lawyer may send a preservation letter asking the insurer or tow yard to hold the vehicle until the data can be downloaded.
Witness statements 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 connect 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. 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.
