Evidence After a Car Accident: Police Reports and Dashcam Video
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. A car accident lawyer usually looks first at the police report and any photos or video, then 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 typically lists the drivers and vehicles involved, with insurance details for each, 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.
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. A car accident lawyer will check the report against the photos and statements.
Dashcam video and photographs
Dashcam footage can capture the seconds before a crash more clearly than any witness. Save the original file with its date and time stamp, instead of a phone recording of the screen, and make 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. Photos taken at the scene show vehicle positions, debris, skid marks and road signs, while photos of injuries taken over several weeks can document healing.
The car's own black box
Many passenger vehicles have an event data recorder https://cesarcopv777.unionquill.com/posts/who-is-liable-in-a-car-crash (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, 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 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. 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 is general information rather than legal advice, and it does not predict the result of any claim.
