What is the primary benefit of wearing a helmet while riding?

Answer: B — To protect against head injuries

Wearing a helmet while riding is primarily beneficial because it provides significant protection against head injuries. In the event of an accident, a helmet can absorb impact forces, reducing the severity of head trauma. Helmets are designed with materials that cushion the skull and brain, offering a critical layer of safety that can prevent or lessen the severity of concussions, skull fractures, and other life-threatening injuries. While looking cool, reducing wind noise, and complying with traffic laws may have their own merits, they do not address the essential purpose of a helmet, which is to safeguard the rider’s head and enhance overall safety on the road.
