§ 71.047  NO-PASSING ZONES.
   (A)   The City Council is authorized to determine those portions of any highway within the city where overtaking and passing or driving on the left of the roadway would be especially hazardous, and may by appropriate signs or markings on the roadway indicate the beginning and end of the zones, and when signs or markings are in place and clearly visible to an ordinarily observant person, every driver of a vehicle shall obey the directions thereof.
   (B)   Where signs or markings are in place to define a no-passing zone as set forth in division (A) above, no driver may, at any time, drive on the left side of the roadway within the no-passing zone or on the left side of any pavement striping designed to mark the no-passing zone throughout its length.
   (C)   This section does not apply under the conditions described in § 71.040(A)(2) and § 71.042(E) of this chapter, nor to the driver of a vehicle turning left into or from an alley, private road or driveway. The pavement striping designed to mark the no-passing zone may be crossed from the left-hand lane for the purpose of completing a pass that was begun prior to the beginning of the zone in the driver’s direction of travel.
