A controlled intersection is characterized primarily by the presence of traffic signals or signs. These signals and signs are designed to manage the flow of traffic and ensure that vehicles and pedestrians can navigate the intersection safely and efficiently. Traffic signals, such as stoplights, dictate when vehicles must stop or go, while signs provide additional guidance on the right-of-way and any necessary stopping conditions. The other options, while they may contribute to the overall traffic management of a roadway, do not specifically indicate that an intersection is controlled. The number of lanes available pertains more to the road's capacity rather than its control mechanisms. The type of pedestrian crossings is related to pedestrian safety but does not alone define whether an intersection is controlled. Speed limit signs inform drivers of the maximum speed allowed but do not manage traffic flow at intersections directly. Thus, the presence of traffic signals or signs is the definitive factor in identifying a controlled intersection.
