§ 6.1.6 SPECIAL STOPS REQUIRED.
   (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 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 upon the basis of an engineering and traffic survey.
   (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 one or more entrances to any such intersection and shall erect a stop sign at every such place where a stop is required; provided said Chief of Police may, in their discretion, establish “yield right-of-way” signs at such intersections as 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.
   (C)   Signs to bear the word “stop”. Every stop sign erected shall bear the word “Stop” in letters not less than eight inches in height and such sign shall at night time be rendered luminous by steady or flashing internal illumination or by a fixed floodlight projected on the face of the sign or by efficient reflecting elements on the face of the sign. Every stop sign shall be located as near as practicable at the nearest line of the crosswalk on the near side of the intersection or at the nearest line of the roadway.
   (D)   Vehicles to stop at stop signs. When stop signs are erected as herein authorized at or near the entrance to any intersection, every driver of a vehicle shall stop before entering the crosswalk on the near side of the intersection or in the event there is no crosswalk shall stop at a clearly marked stop line, but if none, then at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway before entering the intersection except when directed to proceed by a law enforcement officer or traffic-control signal.
   (E)   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.
   (F)   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 being operated without obstructing the passage of other vehicles or pedestrians, notwithstanding any traffic-control signal indication to proceed.
   (G)   Obedience to signal indicating approach of railroad train.
      (1)   Whenever any person driving a vehicle approaches a railroad grade crossing under any of the circumstances stated in this section, the driver of such vehicle shall stop within 50 feet but not less than 15 feet from the nearest rail of such railroad and shall not proceed until they can do so safely.
      (2)   The foregoing requirements shall apply when:
         (a)   A clearly visible electric or mechanical signal device gives warning of the immediate approach of a railroad train;
         (b)   A crossing gate is lowered or when a human flagger gives or continues to give a signal of the approach or passage of a railroad train;
         (c)   A railroad train approaching within approximately 1,500 feet of the highway crossing emits a signal audible from such distance and such train by reason of its speed or nearness to such crossing is an immediate hazard; or
         (d)   An approaching railroad train is plainly visible and is in hazardous proximity of such crossing.
      (3)   It shall be unlawful for any person to drive any vehicle through, around or under any crossing gate or barrier at a railroad grade crossing while such gate or barrier is closed or is being opened or closed. (1985 Code, § 10.02.060)
