What characterizes a controlled intersection?

A controlled intersection is characterized by the presence of traffic lights or signs that determine the right of way for vehicles and pedestrians. This system of control is essential for managing the flow of traffic at busy intersections, helping to reduce conflicts and accidents by clearly indicating to drivers when to stop and when to proceed. Traffic signals and signs provide structured guidance, making it clear who has the right of way, which is crucial for maintaining order on the road.

The other options describe aspects that may occur at intersections but do not adequately define a controlled intersection. For instance, while yielding to pedestrians is important at any intersection, it does not signify control in the same manner; yielding needs to happen whether the intersection is controlled or not. The indication that no vehicles are allowed to stop at an intersection contradicts the fundamental nature of traffic control devices, which sometimes require vehicles to stop. Additionally, stating that only one direction has traffic signals does not provide the complete picture of a controlled intersection, where typically all directions must be signaled for effective operation.
