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

You are following another vehicle at night. When must you dip your high beam?

The answer

  • High beam is always permitted when following
  • When you are 200m or less behind it Correct
  • When you are 50m or less behind it
  • Only if the other driver flashes you

Why that's the answer

You must turn your headlights from high beam to low beam when driving 200m or less behind another vehicle, so you do not dazzle the driver in front through their mirrors.
