How Crash Reports and Dashcam Video Shape an Auto Accident Claim

Evidence from a car crash starts to disappear 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, photos, video and the data stored in the vehicles. This article explains how each source fits into a claim.
What the police report contains
Officers who respond to a crash usually prepare a crash report, often called a police report. It usually records who was driving each vehicle and which insurer covers it, 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 usually come from the responding agency, such as a city police department, a sheriff's office or the state highway patrol, sometimes for a fee.
Insurers rely heavily on the crash report, but it is not the final word on fault. States differ https://stephenyptw868.vantagequill.com/posts/police-reports-dashcam-video-and-car-crash-evidence on whether an officer's opinions can be used at trial. 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 compare the report with the photos and statements.
Video and photo evidence
Dashcam video can show the moments 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 store a backup copy. Traffic cameras and nearby businesses may also have recorded the crash, 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 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, 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 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 an automobile accident attorney may send a preservation letter asking that the vehicle be held until the data can be downloaded.
Witness statements 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. A simple file with the claim number and a log of every call with the adjuster makes later questions easier to answer. A short journal of pain levels and missed work, written while the details are fresh, can also help. This is general information rather than legal advice, and it does not predict the result of any claim.
