Northern Territory · Driver Knowledge Test · Road rules

What is the minimum gap you should keep behind the vehicle in front in good conditions?

The answer

  • Three seconds Correct
  • Half a car length
  • Four car lengths regardless of speed
  • Two seconds

Why that's the answer

The NT Road Users' Handbook asks for a three-second gap in good conditions, which gives you time to see a hazard, react and brake. Stretch it to at least six seconds on wet or slippery roads, on unsealed surfaces, or when dust or spray from a long vehicle ahead blocks your view.
