Evidence After a Car Accident: Police Reports and Dashcam Video
By @emilianodmbq904
The evidence in a car crash claim starts to scatter within hours. Cars are towed and repaired, video is overwritten and witnesses become hard to reach. An auto 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, sometimes called a police report. It usually records who was driving each vehicle and which insurer covers it, and it often includes a diagram, a short narrative and any citations. 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.
Insurers rely heavily on the crash report, but it does not decide fault. States differ on whether an officer's opinions can be used at trial. 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 crash attorney will check the report against 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 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. Scene photos can show where the vehicles stopped and the debris and skid marks around them, while photos of injuries taken over several weeks can document healing.
What the vehicle itself recorded
Many passenger vehicles have https://gunnerzuez228.dovetailscope.com/posts/car-accident-statistics-from-nhtsa-data 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, 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
Witnesses with no stake in the claim often carry weight. Their names and phone numbers should be collected at the scene if it is safe to do so. Medical records link the injuries to the crash, and insurers often point to gaps in treatment 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. This is general information rather than legal advice, and it does not predict the result of any claim.
