What are the signs of drowsy driving?

The signs of drowsy driving primarily include frequent yawning, heavy eyelids, and difficulty keeping the eyes open. These physical indicators suggest that the driver is experiencing fatigue and may not be fully attentive to the driving task. When a driver is drowsy, their reaction times slow down, and their ability to make quick decisions is compromised, increasing the risk of an accident. Recognizing these signs is crucial for a driver's safety and the safety of others on the road, prompting them to take necessary actions, such as pulling over to rest or seeking a safer way to continue their journey.

In contrast, the other choices do not represent signs of drowsy driving. Driving without any distractions indicates attentiveness and focus rather than fatigue. Increased alertness and focus are the opposite of drowsiness, showing that the driver is fully engaged. Listening to loud music can sometimes help keep a driver awake, but it does not inherently indicate drowsiness.
