The evidence in a car crash claim https://felixuguy069.clearhavendigest.com/posts/what-nhtsa-data-show-about-car-crashes starts to scatter within hours. Cars are towed and repaired, video gets recorded over and witnesses become harder to find. A car accident attorney typically starts with the police report and any photos or video, then the data stored in the vehicles. This article explains 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, 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 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 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 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, rather than a phone recording of the screen, and store a backup copy. Traffic cameras and nearby businesses may also have recorded the crash, though many systems record over footage within days or weeks. Scene photos can show where the vehicles stopped and the debris and skid marks around them, and photos of injuries taken over several weeks can show how they changed.
What the vehicle itself recorded
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, 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. 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 is 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. 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 no result can be predicted from it.
