A person with a medical exemption must wear headgear when riding a motorcycle under what condition?

A person with a medical exemption is required to wear headgear when riding a motorcycle at all times if they are under 21. This requirement is in place to ensure safety for younger riders, who may be more vulnerable to injuries in the event of an accident. The law emphasizes protecting individuals who might not yet have developed sufficient riding skills and experience. By mandating headgear, the regulations aim to reduce the risk of head injuries, which is especially critical for younger riders who may struggle more with balance and judgment on the road.

This condition highlights the importance of safety precautions for those who are still in a developmental stage and helps establish a standard that prioritizes the well-being of young motorcycle operators. In contrast, factors such as age or the duration of the ride do not dictate the necessity of headgear for those under 21 with a medical exemption.
