Police Reports, Dashcam Video and Car Crash Evidence

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 lawyer usually looks first at the police report, photos, video and the data stored in the vehicles. This article explains how each source fits into a claim.
What the police report contains
Officers who respond to a crash usually prepare a crash report, often 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 usually come from the responding agency, 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. 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 accident lawyer will compare the report with the photos and statements.
Dashcam video and photographs
Dashcam video can show the moments before a crash better than a witness can. Save the original file with its date and time stamp, instead of 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 event data recorder
Many passenger https://jaidengvnd210.theglensecret.com/who-can-be-held-responsible-for-an-auto-accident 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 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 an automobile accident attorney 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
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. Keeping the claim number in one place, with a log of each call to 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 no result can be predicted from it.
