6-1-4: PASSING AND TURNING RESTRICTIONS:
   A.   General Restrictions: Every person operating or driving a vehicle of any character upon a public street, alley, highway or bridge in the city must observe the following traffic regulations:
      1.   Traffic must everywhere and at all times keep to the right, except as hereinafter provided. Vehicles moving in the opposite direction must pass each other by turning to the right, and must each be to the right of the centerline of the street, alley, highway or bridge. Vehicles moving in the same direction must pass by turning to the left on the part of the one passing and turning to the right on the part of the one being passed. At all turns, curves, corners, crossings and intersections, and particularly where the view is in any manner obstructed, vehicles must slow down and be under complete control, and must keep to the right so that if the width of the street, alley, highway or bridge permits, there is room on their left for the passing vehicle that may at any time suddenly or unexpectedly appear.
      2.   Where traffic is heavy, slow moving traffic must keep as near as possible to the curb. Vehicles turning corners to the right must keep close to the right hand curb; in turning to the left, vehicles must keep to the right and swing full around the intersection of the centerlines of the intersecting streets and avenues. The operator or driver of any vehicle desiring for any reason, either at or between intersections, to turn, must warn all oncoming and following traffic by giving the following hand and arm signal from the left side of the vehicle in the following manner: left turn, hand and arm extended horizontally; right turn, hand and arm extended upward, for a period of not less than two (2) seconds and sufficiently in advance of turning to enable any oncoming car or following car to stop and make the necessary change in course; provided, however, that if the motor vehicle operated and driven is equipped with directional turn indicators on the front and rear of the vehicle which will indicate clearly and positively the direction the operator or driver desires for any reason to turn, the warning herein described may be made by means of such directional turn indicator, provided such signal is exhibited for a period of not less than two (2) seconds prior to a change in course, and sufficiently in advance of turning to enable any person in an oncoming car or a following car to stop and to make the necessary change in course.
      3.   The operator of any vehicle upon any street, alley, highway or bridge within the city, upon being overtaken by another vehicle and receiving a signal or notice from the operator or driver of the vehicle in the rear, that he desires to pass, must without unnecessary delay make every reasonable effort to permit him to do so. (Ord. A-85, 12-5-1955; amd. Ord. A-216, 3-5-1973)
   B.   Turning Between Street Intersections: No automobile or other vehicle shall turn in the streets or avenues in the city between the street intersections except for the purpose of entering or emerging from an alley, and when making turns for the purpose of entering or emerging from an alley, the driver of such vehicle shall give notice of his intention to make such turn either by proper manual signal or by signal by directional turn indicators on the vehicle, all to be done sufficiently in advance of making the same to properly warn all traffic of his intention. (Ord. A-85, 12-5-1955)
