This study compares head injury for motorcycle riders who were involved in traffic accidents in the States of Michigan or Illinois. Since most of the Michigan riders wore helmets because they were required to do so by law but most of the Illinois riders did not because helmet usage is not mandatory in Illinois, this comparison is made to estimate the differences in head injury resulting from compliance with the Michigan safety helmet law. Secondly, this study provides estimates of the actual effectiveness of safety helmets in reducing head injury in the more severe, higher speed accidents which occurred on Interstate highways and freeways in rural areas of Illinois. Finally, a comparison is made of the extent of helmet usage in a helmet-law State (Michigan) to that in a non-helmet-law State (Illinois).
