What constitutes a separate intersection on a roadway?

A separate intersection is defined as a junction where two or more roadways meet or cross each other. The specification of having the roadways be at least 30 feet apart is significant because it emphasizes physical separation, which has implications for traffic flow and safety. When intersections are spaced out sufficiently, they reduce the likelihood of accidents and allow for clearer traffic management, as drivers can more easily identify where one intersection ends and another begins.

Other choices, while they might relate to aspects of pedestrian movement or traffic control, do not accurately capture the definition of a separate intersection. The presence of a pedestrian crossing, traffic signals, or designated turn lanes can exist in various configurations but does not inherently define an intersection as separate from others on the roadway. The key factor here is the physical distance and configuration of the roadways involved.
