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.

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.
