Helmet laws vary by state, but the majority of states have laws that mandate helmet use for all riders or impose specific requirements based on age or experience.
It's important to note that laws can change over time, and there may be updates or revisions to helmet laws in different states since my last knowledge update. Therefore, it is always recommended to consult the current laws and regulations of the specific state in question or contact the appropriate authorities for the most up-to-date information regarding helmet requirements for children operating motorcycles.
