§ 72.08 NO-PASSING ZONES.
   (A)   Council is authorized to determine those portions of any highways within the village 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. Upon request of a local school board, Council shall determine whether a hazardous situation exists at a particular location and warrants a no-passing zone. If Council determines that a no-passing zone is warranted, the school board and Council shall share equally the cost of designating the no-passing zone by signs and markings. When such signs and 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 § 72.01 (A)(2), § 72.03(D-5), 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.
