An intersection is a junction or an area of the roadway where two or more roads cross or meet. An intersection can be four-way (or crossroads), three way (T-junction or Y-junction, sometimes refer to as a fork), or five or more ways.
How are intersections controlled?
- Intersections with less traffic or slow traffic are usually controlled by stop or yield sign.
- Intersections with heavy traffic or fast traffic are usually controlled by stop lights.
- Intersections in residential areas are usually controlled by stop or yield signs.
- Some intersections are controlled by roundabouts.
