§ 3-9-89. Visibility at road intersections.

(a)

Clear sight triangles shall be required at the intersection of all vehicular travel ways to maintain adequate visibility, safe sight distance, and safe movement of traffic. A sight triangle shall be considered the triangular area at the intersection of two (2) vehicular travel ways where a driver's vision of oncoming traffic must remain unobstructed. Such sight triangles shall consist of two (2) thirty-foot segments (Figure 1) running at the edge of the right-of-way, which meet at the intersection and the third side is the line connecting the ends of the thirty-foot segments farthest from the intersection. For driveways, sight triangles shall consist of two (2) twenty-foot segments (Figure 2) running at the property line, and the third side is the line connecting the ends of the twenty-foot segments farthest from the intersection. There shall be a clear space with no obstruction to vision between a height of two (2) feet and six (6) feet above grade. The county engineer may approve alternative sight triangles under circumstances where the requirements of this section cannot be met. The requirements of this section shall not be deemed to prohibit any necessary retaining wall.

(b)

Trees shall be permitted in the clear space if foliage is cut away within the prescribed heights. Lamp posts and sign posts shall be permitted if illuminating fixtures and sign faces are not within the prescribed clear space.
