:Lawyers litigating vehicular crashes often face questions related to how a driver’s actions contributed to a crash. The proliferation of event data recorders (EDRs) and dash or windshield mounted cameras has provided a clearer picture of driver actions preceding crashes. These systems provide a window into the specific actions a driver took prior to the crash, enabling those actions to be evaluated. But the meaning of the data from these EDRs and video systems is not always obvious on the surface. The data needs to be interpreted using methods that will be admitted at the time of trial. This presentation presents a series of real-world case studies in which event data and video were analyzed to reveal driver actions that caused a crash. Attorneys attending this presentation will leave with an understanding of the crash data available on newer vehicles and after-market dash cams and how this data can be used to evaluate a driver’s role in causing a crash.
