Evidence After a Car Crash: Police Reports and Dashcam Video
The evidence in a car crash claim starts to scatter within hours. Vehicles get towed and repaired, video is overwritten and witnesses become hard to reach. A car accident attorney usually looks first at the police report, photos, video and the data stored in the vehicles. Here is how each source fits into a claim.
The crash report
When officers respond to a crash, they 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. Many states also require drivers to report crashes that involve injury, death or property damage above a set amount. Copies are usually available from the agency that responded, 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 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 check the report against the photos and statements.
Photos and dashcam footage
Dashcam footage can capture the seconds before a crash better than a witness can. 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, and photos of injuries taken over several weeks can show how they changed.
What the vehicle itself recorded
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, measured in seconds, not minutes, around the time of a crash. Depending on the vehicle, it may record speed and braking, along with 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 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.
Witnesses and medical records
Independent witnesses carry weight because they have no stake in the claim. Their names and phone numbers should be collected at the scene if it is safe to do so. Medical records connect the injuries to the crash, and gaps in treatment are often used by insurers 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.
