Section 1650. Traffic regulations on county roads

(a)  The  county
  superintendent of highways of a county with respect to county  roads  in
  such county, may by order, rule or regulation:
    1.  Upon  a  roadway  which  is divided into three lanes, allocate the
  center lane exclusively for traffic moving in a specified direction.
    2. Order signs erected directing slow-moving traffic, trucks, buses or
  specified types of vehicles to use a designated  lane,  or  with  signs,
  signals  or  markings designate those lanes to be used by traffic moving
  in a particular direction regardless of the center of the roadway.
    3. Determine those highways or portions of  highways  which  shall  be
  marked  to  indicate where overtaking and passing or driving to the left
  of or crossing such markings would be especially hazardous in accordance
  with the standards, minimum warrants and sign or marking  specifications
  established by the department of transportation.
    4. Temporarily exclude from any portion of any county road 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 his 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 such  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  as  directed  by  the  county
  superintendent  of highways. Upon written application by any operator of
  a vehicle subject to this section, the county superintendent of highways
  may issue a permit providing appropriate exemption to such  vehicle,  if
  it  is  deemed that said vehicle is performing essential local pickup or
  delivery service and that a failure to grant such  permit  would  create
  hardship.  Every such permit may designate the route to be traversed and
  contain other reasonable restrictions or  conditions  deemed  necessary.
  Every such permit shall be carried on the vehicle to which it refers and
  shall be open to inspection of any peace officer, acting pursuant to his
  special  duties,  or  police  officer.  Such  permits  shall  be for the
  duration of the restriction imposed under this section.
    4-a. Exclude trucks, commercial  vehicles,  tractors,  tractor-trailer
  combinations,  or  tractor-trailer-semitrailer combinations in excess of
  any designated weight, designated length, designated  height,  or  eight
  feet  in  width,  from  county highways, except for qualifying or access
  highways or set limits on hours of operation of  such  vehicles.    Such
  exclusion  shall  not  be construed to prevent the delivery or pickup of
  merchandise or  other  property  along  the  highways  from  which  such
  vehicles or combinations are otherwise excluded.
    5. Designate a portion of a slope as a path for the use of bicycles.
    6.  Order  signs or markings to identify the portion of the highway to
  be used for bicycle travel.
    * 7. Designate preferential use lanes for specified types  or  classes
  of vehicles.
    * NB There are two par 7's
    * 7.  Declare  a  snow  emergency and designate any highway or portion
  thereof as a snow emergency route.
    * NB There are two par 7's
    (b) Each such county superintendent of  highways  shall  cause  to  be
  determined,   for   all   bridges  and  elevated  structures  under  his
  jurisdiction, the capacity in tons of  two  thousand  pounds  which  the
  bridge  or  structure  will  safely  carry.  At bridges or structures of
  insufficient strength to carry safely the  legal  loads  permissible  by
  section   three   hundred   eighty-five  of  this  chapter,  the  county

  superintendent of highways shall cause signs to  be  erected  to  inform
  persons of the safe capacity.
    (c)  Each  such county superintendent of highways shall cause signs to
  be erected to inform persons of the legal  overhead  clearance  for  all
  bridges,  and  elevated  structures  on highways under his jurisdiction.
  The legal 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 legislative body of any county with respect to county roads  in
  such  county,  may  by  local law, ordinance, order, rule or regulation,
  provide for the removal and storage of vehicles parked or  abandoned  on
  highways during snowstorms, floods, fire or other public emergencies, or
  found  unattended where they constitute an obstruction to traffic or any
  place where stopping, standing or parking is  prohibited,  and  for  the
  payment  of reasonable charges for such removal and storage by the owner
  or operator of any such vehicle.
    (e) The legislative body of any county with respect to county roads in
  such county, may by local law or ordinance prohibit vehicles engaged  in
  retail  sales  of frozen desserts as that term is defined in subdivision
  thirty-seven of section  three  hundred  seventy-five  of  this  chapter
  directly  to  pedestrians from stopping for the purpose of such sales on
  any such road or on all such roads. Nothing herein shall be construed to
  prohibit the operator of such vehicle from stopping such vehicle off  of
  such  road,  in  a  safe manner, for the sole purpose of delivering such
  retail product directly to  the  residence  of  a  consumer  or  to  the
  business address of a customer of such retailer.
