  state, may by order, rule or regulation:
    1.  Designate  through highways and order stop signs, flashing signals

  like signs or signals at one or more entrances to such intersection.

  weight,  designated  length,  designated height, or eight feet in width,
  from  highways  or  set limits on hours of operation of such vehicles on
  particular state highways or segments of such highways.  Such  exclusion

  to inform persons of the legal overhead clearance for  all  bridges  and

  clearance shall be one  foot  less  than  the  measured  clearance.  The
  measured  clearance  shall  be  the  minimum  height  to  the  bridge or
  structure measured vertically from the traveled portion of the  roadway.
  On  bridges  or  structures  having  fourteen  feet  or more of measured
  clearance, no such signs shall be required.
    (d) The department of transportation may by order, rule or  regulation
  temporarily  exclude  from  any  portion  of  any  state highway and any
  highway and bridge constructed or to be constructed by the state on  any
  indian  reservation any vehicle with a gross weight of over four or more
  tons or any vehicle with a gross weight  in  excess  of  any  designated
  weight  on  any  wheel,  axle, any number of axles, or per inch width of
  tire when in its opinion such highway would be materially injured by the
  operation of any such vehicle thereon. Such exclusion shall take  effect
  upon the erection of signs on the section of highway from which vehicles
  are  excluded,  and  a  notice  that such vehicles are excluded shall be
  published in a newspaper in the county where the  highway  is  situated.
  The  exclusion  shall remain in effect until the removal of the signs is
  directed by the department of transportation.
