Which of the following statements is true regarding helmet laws for motorcycle riders?

In Indiana, the helmet law stipulates that riders and passengers under 18 years of age must wear a helmet that meets DOT (Department of Transportation) safety standards. This law aims to enhance safety for younger riders, who may have less experience and skill on the road. Additionally, riders operating on a motorcycle permit are typically required to wear a helmet and protective eyewear to ensure their safety while they gain experience riding.

Given this information, the statement that both groups—those under 18 and those on a permit—must adhere to specific helmet requirements aligns with Indiana law, making it true. The combination of these requirements underscores the importance placed on protective gear in order to reduce the risk of injury.

Thus, choosing the answer indicating that both statements A and B are correct reflects an understanding of the safety regulations in place for motorcycle riders in Indiana.
