How far back should you stay behind the vehicle ahead of you while driving?

  1. Three seconds

  2. Five seconds

  3. Two seconds

  4. No more than one car length

The correct answer is: Three seconds

You should maintain a safe follow distance of at least three seconds behind the vehicle ahead of you while driving. Following too closely is dangerous as it reduces your reaction time and increases the risk of a collision. Option B and C do not provide a safe distance as they are too short, while option D does not accurately measure the distance and may lead to a rear-end collision. Therefore, option A is the best choice for maintaining a safe distance while driving.
