Question 5383

When driving while drowsy, fatigued, or under the effects of alcohol, can it affect the driver's ability to react in an emergency situation?

  1. Yes, by decreasing the reaction distance.
  2. Yes, by increasing the reaction distance.
  3. No.
Show answer and explanation

Correct answer: Yes, by increasing the reaction distance.

Yes. Drowsiness, fatigue, and alcohol increase your reaction time. While you take longer to respond, the car keeps moving, so your reaction distance increases. In the image, the driver is yawning while the car ahead is braking. Fatigue can increase reaction time by more than 50%, and alcohol can double it.
