Evidence After a Car Crash: Police Reports and Dashcam Video
By @alexisnsaj856
Evidence from a car crash starts to disappear within hours. Vehicles get towed and repaired, video gets recorded over and witnesses become hard to reach. An auto accident lawyer typically starts with 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 police report
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 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 is not the final word on fault. States differ 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. A car accident lawyer 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, rather than 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, and photos of injuries taken over several weeks can show how they changed.
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 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 https://damiennuxl250.northvaledigest.com/posts/who-is-liable-in-a-car-crash-2 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 link 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. 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.
