So dash cam footage can absolutely make or break a personal injury case, depending on the facts. Video evidence, a lot of the times, removes the guesswork and the he said she said narratives in a case. It shows exactly how the accident happened without question, and shows the position of the vehicles, the traffic signals, and any sort of behavior either driver, or any of the drivers, were exhibiting leading up to the crash. Sometimes it perfectly supports your version of events, and other times it raises some new questions.
The critical step is preserving that footage immediately before it gets lost, deleted, or overwritten, which is very common when it’s available. Clear video evidence drastically impacts how an insurance claim is evaluated and eventually resolved.
