States you have to wear a helmet in?

As of my last knowledge update in October 2023, several states in the U.S. require all motorcyclists to wear helmets, including California, New York, and Illinois. Some states, like Florida and Texas, have helmet laws that apply only to certain age groups or riders without specific safety training. It's important to check local laws, as helmet requirements can vary significantly by state. Always prioritize safety when riding regardless of legal requirements.
