ABSTRACT
Motorcycle crashes are associated with a high incidence of head injuries and fatalities. Helmets have been shown to decrease the risk and occurrence of both head injuries and fatalities in motorcycle crashes, along with a decrease in hospitalizations and healthcare costs. Many states have laws in place requiring all motorcyclists to wear helmets and have shown that laws directly affect these outcomes. Wisconsin is a state in which there is a law regarding helmet use; however, there are contingents. It is required only in those who are younger than 18 years and those with an instructional permit.
