How is a controlled intersection defined?

A controlled intersection is defined as one that is regulated by traffic signs or signal lights. This means that there are specific rules or signals in place to manage the flow of traffic at that intersection. Traffic signals, like stoplights, or signs such as yield, stop, or even yield to pedestrians, provide clear instructions to drivers about when to stop, proceed, or yield. This regulation helps to ensure a safer traffic environment by organizing how vehicles and pedestrians interact at these intersections.

In contrast, an intersection with no signals or signs lacks this type of control, which can lead to confusion and increased risk of accidents. An uncontrolled intersection may rely solely on the driver's judgment, which can be particularly dangerous. A roundabout might have some traffic control features, but defining it solely as a roundabout with no control does not address the broader classification of intersections. Moreover, having stop signs for just one direction indicates an unbalanced control situation, which does not fully define a controlled intersection as it pertains to the regulation of all traffic at that juncture. Thus, option B accurately captures the essence of a controlled intersection, highlighting the presence of traffic management devices that direct vehicular and pedestrian flow.
