What is a common symptom of fatigue while driving?

• A. Increased concentration
• B. Difficulty in maintaining speed
• C. Frequent yawning
• D. Clear vision

Answer: (C)

A common symptom of fatigue while driving is frequent yawning. Yawning is a natural physiological response that indicates a lack of alertness and can signal that the brain is not receiving enough stimulation or oxygen. When drivers experience fatigue, their body's need for rest manifests physically, making them more likely to yawn as their eyes and brain struggle to stay awake. This behavior serves as a warning sign that the driver may be at risk of decreased attention and slower reaction times, which can lead to dangerous driving conditions. Increased concentration typically does not occur in fatigued drivers; instead, fatigue usually leads to a decline in focus. Difficulty in maintaining speed may be a consequence of fatigue, but frequent yawning serves as a more direct indicator of sleepiness. Clear vision remains unaffected by fatigue, as it pertains more to eye health than to alertness or cognitive ability, which can deteriorate when a driver is overly tired.
