Impaired drivers are involved in more than 7,000 crashes in Wisconsin each year. If these drivers don't understand how impaired they are because of their impairment, how can we get them to make better choices?
Associate Professor Heather Barkholtz is working to answer that question. Using driving simulators and clinical research, she's studying how THC and alcohol impair drivers' ability to even recognize that they're impaired — a critical gap in our understanding of road safety.
Her research, conducted in collaboration with the Wisconsin State Laboratory of Hygiene and colleagues across campus, could shape public health messaging and save lives.
