The correct answer is based on the definition of intersections in the context of divided highways. When lanes are 30 feet or more apart, every crossing of each roadway is classified as a separate intersection. This measurement is critical because it emphasizes the level of separation between the directions of traffic, which affects how intersections are defined and understood in terms of traffic law.

In practical terms, the greater separation of 30 feet allows for clearer distinctions between the different roadways. This has implications for traffic management, safety regulations, and enforcement, as it helps in determining the rules that apply at these crossings. Therefore, when considering roadway traffic flow and legal definitions, this 30-foot threshold is significant in defining intersections.

Other options present different distances that do not meet the legal criteria set forth in motor vehicle laws concerning how intersections are delineated. Recognizing this threshold is fundamental to understanding traffic law related to divided highways.
