Final answer:
Most fatigue-related collisions occur late at night, specifically between midnight and dawn. Drivers are more likely to be tired and sleepy during these hours, increasing the risk of accidents.
Step-by-step explanation:
Most fatigue-related collisions occur late at night. The hours between midnight and dawn are particularly dangerous for drowsy driving. This is because our natural sleep patterns are aligned with nighttime darkness, making it more difficult to stay awake and focused during these hours.
For example, studies have found that the peak times for fatigue-related collisions are between 2 a.m. and 4 a.m., and between 12 a.m. and 6 a.m. Overall, driving during these late-night hours increases the risk of accidents due to driver fatigue.
It's important to note that fatigue-related collisions can occur at any time of the day, but the highest risk is during late-night hours when drivers are more likely to be tired and sleepy.
