New data shows people who drink and drive motorcycles in Michigan were much less likely to wear helmets after the state repealed its mandatory helmet law.
Carol Flannagan, Research Director of the Center for the Management of Information for Safe and Sustainable Transportation within the University of Michigan’s Transportation Research Institute. She presented her findings to the Michigan Office of Highway Safety Planning this week.
“The story that I see in the data has to do with the combination of risky behaviors that are kind of all traveling together in the data or going together in some sense,” Flannagan said.
Particularly at risk are those motorcyclists who drink and drive. “Once they are in a crash their probability of dying is much higher,” she said.
