A. The city commission, by motion or resolution, may designate any street or part of street a through street.
B. Whenever the city commission so designates and describes a through street, it shall be the duty of the chief of police to have placed and maintained a stop sign, or, if deemed more appropriate at any intersection, a yield sign, on each and every street intersecting such through street unless traffic at any such intersection is controlled at all times by traffic control signals; provided, however, that at the intersection of two (2) such through streets or at the intersection of a through street and a heavy traffic street not so designated, stop signs shall be erected at the approaches of either of said streets as may be determined by the chief of police if deemed desirable.
