What are the signs of drowsy driving?

Frequent yawning, trouble focusing, and heavy eyelids are clear indicators of drowsy driving because they are physical manifestations of fatigue. Yawning often signals that the body is trying to get more oxygen or is on the verge of sleep. When a driver experiences difficulty focusing, it suggests that their attention is waning, which can impair their ability to respond to changing conditions on the road. Heavy eyelids can be a strong sign that the driver is struggling to keep their eyes open, highlighting a significant risk factor for falling asleep at the wheel. Recognizing these signs is crucial for maintaining road safety, as they indicate the need for rest before continuing to drive.

The other choices include behaviors that might indicate a loss of control or distractions while driving, but they do not specifically point to the signs of drowsiness. Increased speed and swerving may suggest impairment or reckless driving, while frequent lane changes and aggressive driving indicate a different type of risk behavior. Listening to loud music may help some drivers stay awake, but it isn't a recognized symptom of drowsiness and doesn't capture the physical signs of fatigue that are essential for identifying drowsy driving.
