Which of the following is NOT true about helmet use?

The statement that helmets are equally effective in preventing neck and head injuries is not accurate. While helmets provide significant protection for the head and can reduce the severity of head injuries, they are primarily designed to absorb impact forces to protect the skull and brain. The effectiveness of helmets in preventing neck injuries is less clear; they do not provide the same level of protection for the neck as they do for the head. Factors such as the design of the helmet, the way it fits, and the conditions of the crash all affect the likelihood of neck injuries occurring.

In contrast, the other statements are based on well-supported evidence. Helmets can indeed reduce the severity of head injuries during low-speed crashes; they are designed to absorb impact energy and distribute forces away from critical areas. Research also shows that unhelmeted riders are at a much higher risk of fatal head injuries in the event of a crash. Additionally, wearing a helmet on highways is strongly advised as speeds tend to be higher, leading to more severe outcomes in the event of an accident.
