According to the National Conference of State Legislatures, when Florida repealed its motorcycle helmet law for adults in 2000, motorcycle fatalities jumped from 259 in 2000 to 413 in 2009. More riders under the age of 21, who are still required to wear helmets, were also not wearing them because it is difficult to enforce a law when it applies to only one portion of the riding population, the group said.
Flannagan said the Office of Highway Safety Planning intends to do a survey this summer to get a better idea of how many riders are wearing helmets.
“I think the basic story from the crash data is pretty straight forward,” she said. “Wearing a helmet reduces the risk and when the helmet law was repealed fewer people wore their helmet.”
