A controlled intersection is an intersection where there are Give Way signs, Stop signs, roundabouts or traffic signals to tell you who has to give way.
Note: double yellow lines at Stop signs and double white lines at Give Way signs and traffic signals are in the process of being replaced with single lines. Also, at Give Way intersections, the words 'Give Way' painted on the road will be replaced by a white triangle.
At an intersection controlled by a Give Way sign:
Single or double white lines are marked on sealed roads to help you stop where you can best see other traffic.
