Under Maryland law, what is required for motorcycle riders?

In Maryland, motorcycle riders are required to wear a helmet and hold a motorcycle endorsement on their driver's license. This requirement is in place to enhance safety for motorcyclists, as helmets provide crucial protection in the event of an accident, significantly reducing the risk of serious head injuries. Additionally, the motorcycle endorsement signifies that the rider has completed the necessary training and has the skills required to operate a motorcycle safely, ensuring both rider and public safety on the road.

The other options do not reflect the comprehensive legal requirements that motorcycle riders must meet in Maryland. Wearing only sunglasses does not offer sufficient protection, and being allowed to wear a helmet only if under 18 ignores the safety benefits for all riders. Furthermore, while carrying a spare helmet for passengers might seem considerate, it is not a legal requirement for motorcycle operation in Maryland.
