A. Scott McKnight

Program Director

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. He has worked on numerous drinking-and-driving-related projects, including studies of the use of vehicle-related sanctions for drinking drivers, intensive supervision programs for drinking drivers, local DUI task forces, high-visibility DWI enforcement, issues surrounding delayed reinstatement of suspended drivers, state alcohol ignition interlock programs, youth and motorcyclist peer-intervention programs, responsible beverage service programs, use of passive breath-testing and transdermal alcohol monitoring devices, and the creation and evaluation of standardized field sobriety tests (SFSTs), including alternative tests for use in a marine environment and for detection of alcohol impairment at low BAC levels.
