The junction of an alley or driveway with a roadway or highway does not constitute an intersection unless the roadway or highway at the junction is controlled by a traffic control device.

   (b)   If a highway includes two roadways that are thirty feet or more apart, then every crossing of each roadway of such divided highway by an intersecting highway constitutes a separate intersection. If both intersecting highways include two roadways thirty feet or more apart, then every crossing of any two roadways of such highways constitutes a separate intersection.

   (c)   At a location controlled by a traffic control signal, regardless of the distance between the separate intersections as described in subsection (b) of this section:

      (1)   If a stop line, yield line, or crosswalk has not been designated on the roadway within the median between the separate intersections, the two intersections and the roadway and median constitute one intersection.

      (2)   Where a stop line, yield line, or crosswalk line is designated on the roadway on the intersection approach, the area within the crosswalk and any area beyond the designated stop line or yield line constitute part of the intersection.

      (3)   Where a crosswalk is designated on a roadway on the departure from the intersection, the intersection includes the area that extends to the far side of the crosswalk.
