What risk does hypothermia pose to motorcyclists?

Answer: C — Reduced reaction time

Hypothermia poses a significant risk to motorcyclists by reducing their reaction time. When a motorcyclist is exposed to cold temperatures for an extended period, their body loses heat, leading to a drop in core body temperature. This physiological change can impair cognitive functions, including decision-making, attention, and the speed at which a person can respond to situations. When riding, quick reactions are essential for safe navigation, especially in emergency scenarios. A delayed reaction due to hypothermia can increase the likelihood of accidents, making it crucial for riders to recognize the signs of cold fatigue and take appropriate measures to stay warm and alert while on the road.
