Evidence After a Car Crash: Police Reports and Dashcam Video
By @milomujl986
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 attorney typically starts with the police report, photos, video and the data stored in the vehicles. Here is how each source fits into a claim.
What the police report contains
When officers respond to a crash, they usually prepare a crash report, sometimes 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. 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, 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 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 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 make 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.
The event data recorder
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, 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 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 motor vehicle accident lawyer may send a preservation letter asking the insurer or tow yard to hold the vehicle until the data can be downloaded.
Witnesses and medical records
Witnesses with no stake in the claim often carry weight. Their names and phone numbers should be collected at the scene if it is safe to do so. Medical records link the injuries to the crash, and insurers often point to gaps in treatment to dispute a claim. A simple https://daltonkzwx688.rivertonbrief.com/posts/uninsured-motorist-pip-and-medpay-coverage-after-a-car-crash 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 article is general information, not legal advice, and it does not predict the result of any claim.
