Approximately what percentage of bike crashes lead to head injury?

• A. 30%
• B. 50%
• C. 75%
• D. 90%

Answer: (C)

Head injuries are a frequent and serious outcome in bike crashes because the head is often the most exposed part of the body during a fall or collision. Safety education commonly uses the figure that about three-quarters of bicycle crash injuries involve the head, which highlights how common these injuries are and why wearing a helmet matters so much. A helmet isn’t foolproof, but it absorbs and distributes impact energy, substantially reducing the risk and severity of head trauma. That high proportion—around 75%—helps explain why this topic emphasizes helmet use: it addresses the biggest risk you face in many crashes. The other options underestimate or describe different contexts, whereas the 75% figure captures the general tendency observed in bike-crash injury patterns.
