Which human factor is a sign of potential drowsiness while driving?

• A. Increased energy
• B. Frequent yawning
• C. Heightened alertness
• D. Concentration

Answer: (B)

Frequent yawning is a well-recognized indicator of drowsiness while driving. It often reflects the body's natural response to fatigue, indicating that the brain is not receiving enough stimulation or rest. When someone is yawning frequently, it is a signal that they may be struggling to maintain alertness and focus, which are critical for safe driving. In contrast, increased energy, heightened alertness, and concentration are signs of an engaged and alert driver. These states imply that a person is alert, active, and capable of reacting appropriately to their driving environment. Therefore, recognizing frequent yawning as a sign of potential drowsiness can help drivers take necessary actions to prevent accidents, such as pulling over to rest or taking a break before continuing their journey.
