Section 39-10-15 - No-passing zones1. The director and local authorities are hereby authorized to determine those portions of any highway under their respective jurisdiction where overtaking and passing or driving on the left side of the roadway would be especially hazardous and may by appropriate signs or markings on the roadway indicate the beginning and end of such zones and when such signs or markings are in place and clearly visible to an ordinarily observant person, every driver of a vehicle shall obey the directions thereof.2. Where signs or markings are in place to define a no-passing zone as set forth in subsection 1, no driver may at any time drive on the left side of the roadway within such no-passing zone or on the left side of any pavement striping designed to mark such no-passing zone throughout its length.3. This section does not apply under the conditions described in section 39-10-08 nor to the driver of a vehicle turning left into or from an alley, private road, or driveway.
