Question 4421

Sleepiness and fatigue — how do they affect driving?

  1. They increase reaction distance.
  2. They increase the ability to react.
  3. They reduce reaction time.
Show answer and explanation

Correct answer: They increase reaction distance.

When you're drowsy or fatigued, you take longer to react between seeing a hazard and pressing the brake pedal. The car keeps moving during that time, so at the same speed you travel more meters before you start braking. That is your reaction distance, which is why it increases. Your reaction time gets longer, and your ability to react decreases.
