Which of the following increases the risk of drowsy driving?

Driving early in the morning is associated with an increased risk of drowsy driving due to several factors. Generally, people experience natural dips in alertness at different times of the day, and early morning hours often coincide with that period, particularly for those whose circadian rhythms are aligned with typical sleep schedules. Many individuals may not have gotten enough sleep the night before, leading to fatigue during these early hours.

Additionally, the early morning is a time when many drivers are just beginning their day and may not yet be fully alert, especially if they didn’t prioritize proper rest. As a result, cognitive functions, reaction times, and overall awareness can be significantly impaired, creating a higher risk of drowsy driving incidents.

In contrast, having a regular sleep schedule promotes better overall alertness, taking short breaks helps maintain focus and reduces fatigue, and consuming energy drinks may temporarily boost energy, although they should not replace adequate rest.
