In the picture, the blue car is following the red car. What minimum gap should the blue car's driver keep?
Correct answer: A gap of at least 3 seconds.
Answer options
AA gap of at least 3 seconds Correct
BA gap of 1 second
CA gap of 2 seconds
Why
Use the 3-second rule: once the red car passes a fixed landmark, the blue car should take at least three seconds to reach that same spot, so a 1- or 2-second gap is too short. On slippery roads, in darkness or bad weather, or when following a motorcycle or a large vehicle, Delaware advises a 4-second gap.
