In what kind of motorcycle crash can wearing a helmet reduce the chance of a fatal head injury?

Wearing a helmet can significantly reduce the risk of fatal head injuries in any motorcycle crash, regardless of speed. Helmets are designed to absorb the impact of a collision and protect the head from severe trauma.

Whether a crash occurs at low speeds—where a rider might fall off or be thrown from the motorcycle—or at high speeds, where the impact is more severe, a helmet acts as a crucial line of defense. Studies have shown that helmets can decrease the likelihood of both head injuries and fatalities in motorcycle accidents, emphasizing the importance of helmet use in providing life-saving protection.

In crashes with no impact, the helmet would not be relevant since there is no collision to mitigate. Therefore, while helmets are essential safety gear in all riding situations, their effectiveness is particularly evident in the context of impact-related crashes.
