Police Reports, Dashcam Video and Car Accident Evidence
Presented by @troyubzw080
Evidence from a car crash starts to disappear within hours. Cars are towed and repaired, video is overwritten and witnesses become hard to reach. A car accident lawyer usually looks first at 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 crash report
Officers who respond to a crash usually prepare a crash report, sometimes called a police report. It typically lists the drivers and vehicles involved, with insurance details for each, along with a diagram, a short narrative and any citations issued. 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.
Insurers rely heavily on the crash report, but it does not decide 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. An auto accident attorney will check the report against the photos and statements.
Video and photo evidence
Dashcam video can show the moments before a crash better than a witness can. Keep the original file with its timestamp, instead of 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. 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.
The event data recorder
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, seconds rather than 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 when a car is repaired or sold for salvage. Total loss vehicles are often moved to salvage auctions within weeks, so an automobile accident https://shaneoxia807.talesignal.com/posts/what-nhtsa-data-show-about-traffic-deaths attorney may send a preservation letter asking the insurer or tow yard to hold the vehicle until the data is downloaded.
Witnesses 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.
