Which of the following actions is a sign of drowsy driving?

Absent-mindedness is a significant sign of drowsy driving because it indicates a lack of attention and focus that often accompanies fatigue. When a driver is drowsy, their mind may wander, leading to failures in concentration on the road, missed traffic signs, or an inability to react promptly to changing traffic conditions. This diminished awareness can be dangerous, as it increases the likelihood of accidents. Recognizing this behavior as a warning sign can prompt drivers to take necessary precautions, such as pulling over to rest or switching drivers when feeling tired.

Engaging in other activities like using cruise control, driving with the window down, or listening to loud music may not directly indicate drowsiness but are rather actions anyone might take while driving. However, these actions do not necessarily reflect attention or awareness levels. Therefore, identifying absent-mindedness as a sign of drowsy driving highlights the importance of being aware of one’s mental state while operating a vehicle.
