WASHINGTON — The average medical claim from a motorcycle crash rose by more than one-fifth last year in Michigan after the state stopped requiring all riders to wear helmets, according to an insurance industry study. Across the nation, motorcyclists opposed to mandatory helmet use have been chipping away at state helmet laws for years while crash deaths have been on the rise.
For more than 40 years, Michigan required all motorcycle riders to wear helmets. 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.
