A. Authority To Erect Stop Signs: Whenever any of the laws of the City designate and describe a through street, it shall be the duty of the Chief of Police to place and maintain a stop sign on each and every street intersecting such through street or intersecting that portion thereof described and designated as such, unless traffic at any such intersection is controlled at all times by traffic-control signals; provided however, that at the intersection of two (2) 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 upon the basis of an engineering and traffic study. (1980 Code § 10.7.1)
B. Intersections Where Stop Required: The Chief of Police is hereby authorized to determine and designate intersections where particular hazards exist upon other than through streets and to determine whether vehicles shall stop at every such place where a stop is required; provided, that said Chief of Police may, at his discretion, establish "yield right-of-way" signs at such intersections as it is deemed advisable. Such signs shall indicate that an intersection may be entered without stopping if no vehicles are approaching along the street whereon the yield right-of-way signs control entering traffic. (1980 Code § 10.7.2)
C. Emerging From Alley, Driveway Or Building: The driver of a vehicle within a business or residence district emerging from an alley, driveway or building shall stop such vehicle immediately prior to driving onto a sidewalk or onto the sidewalk area extending across any alleyway or driveway, yielding the right of way to any pedestrian as may be necessary to avoid collision and, upon entering the roadway, shall yield the right of way to all vehicles approaching on said roadway. (1980 Code § 10.7.3)
D. Stop When Traffic Obstructed: It shall be unlawful for any driver to enter an intersection or a marked crosswalk unless there is sufficient space on the other side of the intersection or crosswalk to accommodate the vehicle he is operating without obstructing the passage of other vehicles or pedestrians, notwithstanding any traffic-control signal indication to proceed. (1980 Code § 10.7.4)
