Which of the following is a legal requirement for cycle riders in Texas?

In Texas, there is a legal requirement for certain motorcycle riders to wear a helmet. Specifically, riders under the age of 21 must wear a helmet in compliance with state laws. Additionally, it is recommended for all riders to wear helmets for safety reasons, as helmets significantly reduce the risk of head injuries in the event of an accident. While options like having a horn or a rearview mirror may contribute to a motorcycle’s safety and functionality, they are not mandated by Texas law in the same way that helmet use is for younger riders. Therefore, the requirement for helmet use stands out as a legal necessity for cycle riders in Texas.
