What is a common sign of fatigue while driving?

Frequent yawning or heavy eyes is a well-known indicator of fatigue while driving. When a driver is feeling tired, the body often exhibits signs of drowsiness, which can manifest as yawning, blinking frequently, or having difficulty keeping the eyes open. This is a critical signal that the driver may not be fully alert, increasing the risk of falling asleep at the wheel or experiencing decreased reaction times. Recognizing these symptoms is essential for maintaining safety on the road, as it is advisable for fatigued drivers to pull over and rest or find a safe place to take a break to ensure they remain vigilant and capable of operating the vehicle safely.

In contrast, increased speed may indicate a lack of attention to speed limits but does not inherently signal fatigue. Listening to loud music might be an attempt to stay awake, but it doesn't directly correlate with signs of tiredness. Consistent navigation through traffic demonstrates alertness and engagement in driving, which would not typically happen if a driver were fatigued.
