When are collisions involving drowsiness most likely to happen?

Collisions involving drowsiness are most likely to occur during early morning and late afternoon. During these times, many individuals experience natural dips in energy levels. Early morning hours can coincide with a lack of sleep from the previous night or the body's natural circadian rhythms, which can lead to decreased alertness. Similarly, late afternoon often presents a classic fatigue period stemming from a long day, making it a common time for drivers to feel drowsy. It is vital for drivers to be aware of these peaks in drowsiness to mitigate risks associated with driving while fatigued. Recognizing these high-risk times can help in planning trips more safely or in considering breaks when feeling tired.
