The ease with which sleepiness can occur is not the same throughout the day. The early morning hours (especially between 3 and 5) and the early afternoon hours (approximately between 14 and 16) are particularly conducive to the onset of drowsiness, even after having slept enough. If we are tired or sleepy, the best thing to do is to stop and rest in a suitable place. Every 2 hours or 200 km of driving, we should rest for at least 20-30 minutes to avoid having an accident due to fatigue or drowsiness.
