New South Wales · Driver Knowledge Test (DKT) · Road safety

What following gap should you allow when travelling at higher speeds?

The answer

  • Keep the same 3 seconds
  • At least 5 seconds Correct
  • Reduce it to 2 seconds to keep traffic flowing
  • One car length for every 10 km/h

Why that's the answer

At higher speeds you should increase the gap to allow at least 5 seconds, so you have enough time to react and brake. Your speed directly affects the distance you need to stop safely.
