"Intersection" means more than the crossroads you picture — and that matters, because the give-way rules apply wherever one is.
What counts as an intersection
An intersection is anywhere two or more roads join or cross, or where a public entrance or exit joins a road. That includes the entrances and exits of supermarkets, petrol stations, and public car parks such as those at airports and hospitals — so the give-way rules apply there too, not just at street corners.
