What are the signs of drowsy driving?

Frequent yawning and drifting from lanes are clear signs of drowsy driving. When a driver experiences exhaustion, they may find it difficult to maintain concentration and stay within their lane, which increases the risk of an accident. Yawning is a physiological response to fatigue, indicating that the body is signaling a need for rest. This behavior is critical to recognize as it suggests the driver is not fully alert, which can lead to impaired reaction times and poor judgment on the road.

In contrast, increased speed and quick lane changes could suggest aggressive or distracted driving rather than drowsiness. Better focus and alertness would indicate a driver is fully awake, which directly contradicts the understanding of drowsy driving. Listening to loud music may keep a driver more engaged or awake, but it does not serve as a definitive sign of drowsiness. Therefore, recognizing frequent yawning and drifting is essential for identifying when a driver may be too fatigued to operate a vehicle safely.
