Answer:
Each state has different laws pertaining to who must wear motorcycle helmets. The rationale behind teens only having to wear a helmet when an adult may not have to is because teens have a higher risk. Since teens are new drivers, they need to wear helmets to help protect them in case of a wreck. Seasoned drivers are more alert and know the roads and when to drive during certain types of weather. Since teens are new drivers, they may drive in bad weather, not be alert as older adults.
