Evidence After a Car Accident: Police Reports and Dashcam Video
By @mariotdkt975
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 attorney 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.
The crash report
When officers respond to a crash, they usually prepare a crash report, often 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, 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 is not the final word on fault. Rules on using an officer's opinions at trial vary by state. 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 check the report against the photos and statements.
Photos and dashcam footage
Dashcam video can show the moments before a crash more clearly than any witness. Keep the original file with its timestamp, instead of a phone recording of the screen, and store a backup copy. Traffic cameras and nearby businesses may also have recorded the crash, but many systems overwrite 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.
What the vehicle itself recorded
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, surrounding 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 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. Collect their names and phone numbers at the scene when it is safe. Medical records link the injuries to the crash, and https://emilianocttq868.lakeviewbrief.com/posts/nhtsa-traffic-crash-statistics-on-speeding-and-drunk-driving 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 is general information rather than legal advice, and it does not predict the result of any claim.
