Which guideline gives the minimum space you should keep behind the vehicle in front of you?
Correct answer: A 3-second gap.
Answer options
AA 4-second gap
BA 5-second gap
CA 3-second gap Correct
Why
The commonly taught minimum is a 3-second gap, which you can check by counting from when the vehicle ahead passes a fixed object until you reach it. More space is wise in bad weather or heavy traffic, but 3 seconds is the basic minimum.
