Amend paragraphs 10 and 12 of MUTCD Section 3B.16 to read:

If used, stop line should be placed a minimum of 4 feet in advance of the nearest crosswalk line at controlled intersections. Yield lines at roundabout intersections as provided in Section 3C.04. In the absence of a marked crosswalk, the stop line or yield line should be placed at the desired stopping or yielding point, in no case less than 4 feet from the nearest edge of the intersecting roadway.

If used at an unsignalized midblock crosswalk, stop lines should be placed adjacent to the Stop Here for Pedestrians sign located 20 to 50 feet in advance of the nearest crosswalk line, and parking should be prohibited in the area between the stop line and the crosswalk (see Figure 3B-17).
