Evidence After a Car Accident: Police Reports and Dashcam Video
Evidence from a car crash starts to disappear within hours. Cars are towed and repaired, video is overwritten and witnesses become hard to reach. A car accident attorney 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 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, 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. 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 compare the report with the photos and statements.
Dashcam video and photographs
Dashcam video can show the moments before a crash more clearly than any witness. Save the original file with its date and time stamp, rather than a phone recording of the screen, and make a backup copy. Nearby businesses, buses and traffic cameras may have recorded the crash too, 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 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, surrounding a crash. Depending on the vehicle, it may record speed and braking, along with seat belt use. https://dominickaonf862.northcrestbrief.com/posts/nhtsa-traffic-crash-statistics-on-speeding-and-drunk-driving 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 when a car is repaired or sold for salvage. Total loss vehicles are often moved to salvage auctions within weeks, so a car 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. 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. 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.
