What denotes a controlled intersection?

A controlled intersection is characterized by the presence of traffic signals or signs that regulate the flow of traffic. This means that vehicles and pedestrians must obey the instructions given by these signals or signs, which helps to organize the right-of-way and maintain order at the intersection. When traffic signals or signs are in place, they provide clear guidance on when to stop, yield, or go, contributing to safer and more efficient traffic management.

In contrast, an intersection marked with a roundabout does not necessarily indicate a controlled intersection in the same manner as traffic signals or signs, as roundabouts operate on a flow-control principle where yielding is based on traffic approaching the roundabout. Similarly, intersections with wooden barriers do not directly serve to control traffic and may be more about physical obstruction rather than regulation. Finally, an intersection with no traffic signs at all would be classified as an uncontrolled intersection, where drivers must navigate without specific signals guiding their actions. This can lead to ambiguity and increased risk of accidents.
