"Sight triangle area" means:
A. The area within the three (3) points forming a triangle described as follows:
1. The point required for a safe stopping distance based on line of sight, determined by the posted speed for the roadway where a vehicle approaching an intersection is not required to obey a stop or yield sign, aligned using the most conservative of:
a. Three feet (3') off center line paint toward the curb in the direction of vehicular travel;
b. Three feet (3') off perceived centerline of traveled path toward the curb in the direction of vehicular travel; or
c. Five feet (5') off of fog line paint toward the center of the road;
2. The point where the vehicle approaching the intersection would collide with a vehicle or pedestrian entering the intersection from the cross street; and
3. The point on the pavement where the vehicle or pedestrian on the cross street connecting to the intersection is directed to stop or yield or, if the cross street lacks pavement marking, the point five feet (5') off the edge of gutter for the approaching vehicle.
B. The minimum sight triangle distance where curbs are installed is that portion of a corner lot lying within a triangular area formed by measuring back along each of the curb lines to a point forty feet (40') from the intersection of said curb lines, and then connecting the two (2) points thus established with a third line. An example of a "sight triangle area" at an intersection where curbs are installed is marked off by the shaded area in the following illustration:
C. The minimum sight triangle distance where no curbs are installed is that portion of a corner lot lying within a triangle area formed by measuring back along the property lines adjacent to the intersecting streets to a point on each property line twenty feet (20') back from the intersection of said property lines and then connecting the two (2) points thus established with a third line. An example of a "sight triangle area" at an intersection where curbs have not been installed is marked off by the shaded area in the following illustration:
