What effect can drowsiness have on driving?

  1. Increase in speed limit

  2. Improved reflex time

  3. Slower reaction time

  4. Higher risk of collision

The correct answer is: Higher risk of collision

Drowsiness can impair a person's ability to drive safely, making them less alert and attentive while driving. This can lead to slower reaction times, making it difficult for drivers to respond quickly to changes on the road, such as sudden stops or lane changes. This puts them at a higher risk of collision, as they may not be able to avoid potential hazards or obstacles in a timely manner. Therefore, drowsiness can have a negative effect on driving and increase the chances of getting into an accident. Options A and B are incorrect because they suggest positive effects, which are not true for drowsiness. Option C may seem like a possible answer since drowsiness can result in slower reaction time, but it is not the specific and direct effect of drowsiness on driving.
