        (a)  Establishment and marking.--The department and local
     authorities may determine those portions of any highway under
     their respective jurisdictions where overtaking and passing or
     driving on the left side of the roadway would be especially
     hazardous and shall by appropriate signs or markings on the
     roadway indicate the beginning and end of such zones and when
     the signs or markings are in place and clearly visible to an
     ordinarily observant person every driver of a vehicle shall obey
     the directions of the signs or markings. Signs shall be placed
     to indicate the beginning and end of each no-passing zone.
        (b)  Compliance by drivers.--Where signs and markings are in
     place to define a no-passing zone as set forth in subsection
     (a), no driver shall 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 a no-passing zone throughout
     its length.
        (c)  Application of section.--This section does not apply
     under the conditions described in section 3301(a)(2) and (5)
