What effect does driving while drowsy have on a driver?

Driving while drowsy significantly affects a driver's ability to operate a vehicle safely. One of the primary consequences is a slower reaction time, which means a drowsy driver may not respond promptly to traffic signals, road hazards, or sudden changes in traffic conditions. This delay in reaction can lead to dangerous situations on the road.

Additionally, drowsiness can cause blurry vision, impairing the driver's ability to see clearly, which is critical for safe driving. When drivers do not have adequate clarity of vision, their ability to judge distances, speed, and the behavior of other drivers is compromised, increasing the risk of accidents.

In contrast, increased awareness of surroundings, improved focus on driving tasks, and heightened care for road rules are not outcomes associated with driving while drowsy. Instead, drowsiness typically leads to a decrease in these abilities, making it vital for drivers to prioritize alertness to safeguard their own safety and that of others on the road.
