Which of the following is a sign of fatigue while driving?

  1. Increased focus on the road

  2. Heavy eyelids and day-dreaming

  3. Feeling restless and motivated

  4. Sharp reflexes and quick decision making

The correct answer is: Heavy eyelids and day-dreaming

Heavy eyelids and day-dreaming are indeed signs of fatigue while driving. Fatigue can impair a driver’s ability to concentrate and maintain attention on the task at hand, leading to symptoms such as feeling heavy-eyed or experiencing a wandering mind. This state can significantly decrease a driver's awareness of their surroundings, resulting in slower reaction times and a higher risk of accidents. Recognizing these signs is crucial for drivers to ensure their safety and that of others on the road. The other options reflect positive signs of alertness and focus, which are contrary to the effects of fatigue. Increased focus, feeling restless and motivated, and having sharp reflexes indicate a driver is alert and engaged, not fatigued. Therefore, the presence of heavy eyelids and day-dreaming effectively illustrates the diminishing cognitive and physical capabilities associated with fatigue.
