Evidence After a Car Crash: Police Reports and Dashcam Video
Presented by @fernandosxop703
Evidence from a car crash starts to disappear within hours. Vehicles get towed and repaired, video is overwritten and witnesses become harder to find. An auto accident lawyer 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.
The police report
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. 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, often for a small fee.
A crash report is influential in insurance claims, but it is not the final word on 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.
Dashcam video and photographs
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. 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, while photos of injuries taken over several weeks can document healing.
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, measured in seconds, not 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, https://caidenkuvh475.fairmontdigest.com/posts/what-to-expect-from-the-insurance-adjuster-after-a-car-crash 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. Insurers often move a total loss vehicle to a salvage auction quickly, so a motor vehicle accident lawyer may send a preservation letter asking that the vehicle be held until the data can be 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 insurers often point to gaps in treatment 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 it does not predict the result of any claim.
