What are the signs of a fatigued driver?

Identifying the signs of a fatigued driver is crucial for maintaining road safety. The correct response highlights typical behaviors associated with fatigue, such as yawning, drifting out of lanes, and difficulty concentrating. Yawning often signals a lack of alertness, as it is a physiological response to tiredness. When a driver drifts out of lanes, it indicates a loss of focus and control, which are common symptoms of fatigue. Additionally, difficulty concentrating can lead to an increased risk of accidents, as it compromises a driver's ability to react to changing road conditions and traffic situations. Recognizing these signs can help prevent dangerous situations on the road, prompting either the driver or others to take action to improve safety.
