What is the helmet law for motorcycle riders in Wisconsin?

In Wisconsin, the helmet law stipulates that motorcycle riders are required to wear helmets only until they reach the age of 18. This reflects the state's approach to motorcycle safety, which allows adults over the age of 18 the option to ride without a helmet. The rationale behind this law is rooted in the belief that individuals who are 18 or older can make their own decisions regarding safety equipment. However, this law does promote safety for younger riders, as their vulnerability to severe injury in the event of an accident is especially noted.

Considering the other options, the law does not mandate helmets for all riders or state that helmets are optional at all ages. Additionally, the requirement is not limited to passengers, as the law specifically pertains to riders under the age of 18, indicating a targeted approach rather than a blanket requirement for all individuals on a motorcycle.
