Which factor can lead to drowsy driving?

Inadequate rest before driving is a significant factor that can lead to drowsy driving. When a driver fails to get enough sleep, their ability to concentrate, react quickly, and make sound judgments is severely compromised. Sleep deprivation impacts cognitive function, slowing reaction times and impairing decision-making skills, much like alcohol intoxication. This lack of alertness can result in decreased awareness of surrounding traffic and an increased likelihood of falling asleep at the wheel, making it essential for drivers to prioritize adequate rest and avoid long periods of driving when fatigued.

Other factors, such as high energy levels or listening to music, may not directly contribute to drowsiness and can even enhance alertness under certain conditions. Taking frequent breaks can also help combat fatigue rather than induce it, promoting greater focus and preventing the onset of tiredness during long drives. Thus, ensuring adequate rest is the most critical step in preventing drowsy driving.
