    (a) The Oklahoma Department of Highways or other designated
authorities are hereby authorized to determine those portions of any
highway where overtaking and passing or driving to 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 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.
    (b) Where signs or markings are in place to define a no-passing
zone as set forth in paragraph (a) no driver shall at any time drive
to 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.
