The 2 ft. distance behind stop line is typical depending on the intersection <br />geometrics; a loop can be in front of the stop line. <br />2. Loop(s) shall be centered transversely in the travel lane. <br />3. The saw slot for the line from detector housing to the circular loop shall be <br />approximately perpendicular to the tangent of the loop at the point of intersection.
