An intersection is defined by which of the following?

The correct choice regarding the definition of an intersection pertains to the prolongation of lateral curb lines or boundaries of roadways. An intersection is essentially the area where two or more roadways meet or cross each other. This definition is crucial for understanding traffic management and driver behavior at such points.

When considering curb lines or roadway boundaries, they serve as the extendable lines that define the limit of roadway space. Where these lines intersect—whether at a right angle or an obtuse angle—the intersection is formed. This definition aids drivers and pedestrians in identifying where they are expected to yield or stop and facilitates the organization of traffic flow.

The other choices, while related to road use and pedestrian safety, do not capture the full legal definition of what constitutes an intersection. The mention of weight limits, pedestrian areas, or general highway openness lacks the specific reference to the intersection’s physical geometry that makes option B the most accurate. Understanding intersections is vital for safe navigation and adherence to motor vehicle laws, as they are often high-traffic areas where the potential for accidents increases.
