What defines a controlled intersection?

Answer: B — An intersection regulated by traffic signals or signs

A controlled intersection is defined by the presence of traffic signals or signs which regulate the flow of vehicles and pedestrians. These signals or signs direct traffic, helping to establish the right-of-way and enhance safety for all road users. In such intersections, drivers are required to follow the signals or signs, ensuring a systematic approach to navigating the junction, which can prevent accidents and confusion. In contrast, intersections without any traffic signals or signs would be classified as uncontrolled intersections, where drivers must rely on their judgment to determine right-of-way. This lack of regulation can lead to increased hazards. Furthermore, intersections limited solely to pedestrian access or those with no markings or signs do not qualify as controlled intersections because they lack the necessary regulatory elements that define the flow of vehicle traffic in a structured manner.
