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

When may you use your fog lights?

The answer

  • Only in fog or heavy rain, or when smoke or dust limits your vision Correct
  • Only between sunset and sunrise
  • Only on motorways
  • Any time you want extra visibility

Why that's the answer

Fog lights may only be used in fog or heavy rain, or when other conditions such as smoke or dust limit your vision — and you must switch them off once conditions improve. If your vehicle has no fog lights you can use low beam headlights.
