Final answer:
Arizona law requires only riders under the age of 18 to wear helmets on motor-driven cycles, not those over 18. The statement is False.
Step-by-step explanation:
The statement that Arizona requires all riders of motor-driven cycles over the age of 18 to wear a helmet is FALSE. In Arizona, only riders under the age of 18 are legally required to wear a helmet while operating or riding on a motor-driven cycle. While it's true that helmets can help protect against head injuries and prevent nervous system injuries, Arizona law does not mandate helmet use for all riders.
However, safety experts strongly recommend the use of helmets for riders of all ages to reduce the risk of injury. helmet laws only apply to riders under the age of 18. According to Arizona Revised Statute 28-964, any person under 18 years old who is operating or riding as a passenger on a motorcycle or motor-driven cycle must wear a protective helmet. So, the statement is False.
