What are signs of drowsy driving?

Drowsy driving can greatly impair a driver's ability to focus, make decisions, and react effectively, leading to dangerous situations on the road. The signs of drowsy driving are bodily indications that a person is too fatigued to operate a vehicle safely. Constant yawning and heavy eyelids are classic symptoms of fatigue. These physical manifestations are clear indicators that the driver is struggling to stay alert and may fall asleep at the wheel.

The other options do not accurately reflect signs of drowsy driving. For example, consistently checking mirrors may indicate a conscientious driver but does not signify fatigue. Playing games on mobile devices could be a distraction rather than a sign of drowsiness, and increased speed on the highway may suggest aggressive driving behavior, not necessarily fatigue. Thus, recognizing yawning and heavy eyelids as signs of drowsiness is critical for ensuring the safety of the driver and others on the road.
