We've written before about an unintended consequences of state repeals of motorcycle helmet laws: more organs available for transplant. Here's one more consequence, from Michigan, which stopped requiring helmets last year:
State legislators changed the law last year so that only riders younger than 21 must wear helmets. The average insurance payment on a motorcycle injury claim was $5,410 in the two years before the law was changed, and $7,257 after it was changed - an increase of 34 percent, the study by the Highway Loss Data Institute found.
After adjusting for the age and type of motorcycle, rider age, gender, marital status, weather and other factors, the actual increase was about 22 percent relative to a group of four comparative states, Illinois, Indiana, Ohio and Wisconsin, the study found.
"The cost per injury claim is significantly higher after the law changed than before, which is consistent with other research that shows riding without a helmet leads to more head injuries," David Zuby, chief research officer for the data institute and an affiliated organization, the Insurance Institute for Highway Safety, said.
