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

What makes an area a 'built-up area' for the purposes of the default 50 km/h speed limit?

The answer

  • Any area where houses are visible from the road
  • Any area inside a city or town boundary
  • Street lights and buildings next to the road less than 100m apart Correct
  • Any road with a footpath on at least one side

Why that's the answer

The handbook defines a built-up area as one with street lights and buildings next to the road less than 100m apart. That is the cue to apply the 50 km/h default when no sign is posted.
