An intersection is where:

  • 2 or more streets or roads join or cross
  • a public entrance or exit joins a street or road.

Intersections can include entrances to and exits from supermarkets, petrol stations and other public parking areas, such as airports and hospitals. There are a number of different types of intersections, depending on how many roads meet at the intersection.
