§ 158.09 CORNER ISLAND.
   (A)   When the effective intersection radius is:
      (1)   40 feet, or less, the beginning of the approach radius shall be at least 20 feet from the angular bisector as measured along the face of curb or pavement edge, except:
         (a)   Where a sidewalk exists, the beginning of the approach radius shall not begin nearer the roadway intersection than the back edge of the sidewalk.
      (2)   Greater than 40 feet, the beginning of the approach radius shall not be closer to the roadway intersection than a distance equal to one-half the effective intersection radius as measured from the angular bisector along the face of curb or pavement edge, except:
         (a)   When the highway intersection is 120 or greater, the beginning of the approach radius may begin 20 feet from the angular bisector, as measured along the face of curb or pavement edge.
         (b)   When the highway intersection radius is greater than 80 feet, the beginning of the approach radius may begin 40 feet from the angular bisector.
   (B)   At channelized intersections, the above conditions shall apply unless their use would encourage "wrong-way" operation along a directional portion of the intersection, in which case the corner island control would be determined by factors consistent with § 158.07.
