Scott McKnight has worked in the field of transportation safety research for over 35 years. In this time, he has participated in studies of vehicle operators including motorcycle operators, commercial vehicle operators, recreational boaters, novice drivers, distracted drivers, aggressive drivers, and elderly drivers.
