Under normal conditions, what following distance is safe?
Correct answer: At least 3 seconds.
Answer options
AHalf a second
BAt least 3 seconds Correct
C1 second
Why
A gap of at least 3 seconds gives you time to notice a problem ahead and stop: count the seconds from when the vehicle ahead passes a fixed point until you reach it. A gap of 1 second or less is too short to react, and in poor conditions you should leave even more space.
