Evidence After a Car Crash: Police Reports and Dashcam Video
Presented by @franciscowmzw340
Evidence from a car crash starts to disappear within hours. Vehicles get towed and repaired, video is overwritten and witnesses become harder to find. A car accident lawyer usually looks first at the police report, photos, video and the data stored in the vehicles. Here is how each source fits into a claim.
The crash 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, such as a city police department, a sheriff's office or the state highway patrol, often for a small 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 crash 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. Nearby businesses, buses and traffic cameras may have recorded the crash too, 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 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. 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
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 https://daltonczuy270.terracolumn.com/posts/who-is-liable-in-a-car-accident 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.
