Police Reports, Dashcam Video and Car Accident Evidence
By @mariotdkt975
Evidence from a car crash starts to disappear within hours. Vehicles get towed and repaired, video gets recorded over and witnesses become harder to find. 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 typically lists the drivers and vehicles involved, with insurance details for each, 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 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. Rules on using an officer's opinions at trial vary by state. When a report has a factual error, such as a wrong plate number, the agency may accept a request to correct or supplement https://johnathanafkw370.iamarrows.com/what-to-expect-from-the-insurance-adjuster-after-a-car-accident it. An auto accident attorney will compare the report with the photos and statements.
Photos and dashcam footage
Dashcam video can show the moments before a crash better than a witness can. Keep the original file with its timestamp, rather than a phone recording of the screen, and make a backup copy. Nearby businesses, buses and traffic cameras may have recorded the crash too, though many systems record over 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, seconds rather than 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 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. Insurers often move a total loss vehicle to a salvage auction quickly, so a motor vehicle accident lawyer may send a preservation letter asking the insurer or tow yard to hold the vehicle until the data is downloaded.
Witness statements and medical records
Independent witnesses carry weight because they have no stake in the claim. 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. A short journal of pain levels and missed work, written while the details are fresh, can also help.
