When do most tiredness-related accidents occur?

Most tiredness-related accidents occur between 11:00pm and 6:00am because this time frame coincides with the natural circadian rhythm of human bodies, during which people are typically meant to be asleep. The body experiences a decrease in alertness and an increase in fatigue during the late night and early morning hours.

At this time, drivers are more likely to experience lapses in concentration, slower reaction times, and decreased decision-making skills, all of which significantly increase the risk of accidents. Awareness of this peak period for tiredness-related incidents reinforces the importance of adequate rest before driving, particularly during the times when fatigue is most likely to impair one's ability to operate a vehicle safely.
