What is a partially controlled intersection?

Answer 1

Controlled intersections have traffic lights, yield signs or stop signs to control traffic. At a controlled intersection where you face a green light, drive carefully through the intersection at a steady speed. If the light has been green for a while, be prepared to stop when it turns yellow. However, if you are already so close that you cannot stop safely, drive through the intersection with caution. Where you face a red light, come to a complete stop and wait until the light turns green.

When you approach an intersection on a main road, and the intersection is blocked with traffic, stop before entering the intersection and wait until the traffic ahead moves on. This does not apply if you are turning left or right.

At a controlled intersection where you face a yield sign, slow down or stop if necessary and wait until the way is clear before driving through the intersection. At a controlled intersection where you face a stop sign, come to a complete stop. Drive through the intersection only when the way is clear (Diagram 2-15).

Answer 2

A partially controlled intersection is an intersection in which some, but not all of the approaches are controlled by traffic signals/signage. A very common example of this is when a minor street crosses a major street. Often the minor approaches will have stop signs that force road users to stop before entering or crossing the major roadway, but does not have any form of control on the major approaches allowing road users on the major roadway to proceed freely through the intersection.
