Police Reports, Dashcam Video and Car Crash Evidence
By @gregorylvgk597
The evidence in a car crash claim starts to scatter within hours. Vehicles get towed and repaired, video is overwritten and witnesses become harder to find. 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 usually records who was driving each vehicle and which insurer covers it, 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, 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. If the report contains a https://deanpatq247.solsticebrief.com/posts/questions-to-ask-before-hiring-an-auto-accident-lawyer-2 factual error, such as a wrong plate number, the agency may accept a request for a correction or a supplement. A car crash attorney 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, rather than a phone recording of the screen, and store 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, while photos of injuries taken over several weeks can document healing.
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, 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 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. Insurers often move a total loss vehicle to a salvage auction quickly, so a car accident attorney may send a preservation letter asking the insurer or tow yard to hold the vehicle until the data is downloaded.
Witnesses 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 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. 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 no result can be predicted from it.
