Sec. 4-3.109.   Parking on County roads and highways and State highways affected by a labor controversy.
   (a)   It shall be unlawful for any person to park or leave standing any unattended motor vehicle at the localities designated as affected by a labor controversy in accordance with the provisions of subsection (b)of this section, and any vehicle so parked or left standing may be removed pursuant to Division 11 of the Vehicle Code of the State.
   (b)   After considering a recommendation thereon by the Sheriff-Coroner, the Director of Public Works may designate those portions of roads, streets, or highways as localities affected by a labor controversy if he finds as follows:
   (1)   A labor controversy exists; and
   (2)   That controversy affects a designated portion of a County road, street, or highway or a State highway in that parked motor vehicles impede the flow of traffic, block the vision of law enforcement personnel at the locality, diminish the safety of persons present at the locality, or otherwise constitute an invasion of the public health, safety, or general welfare at the locality.
   (c)   Parking restrictions shall be placed upon State highways only upon a request, made in writing, by the Board to the Department of Transportation of the State.
   (d)   Any provision of this section which regulates traffic or delegates the regulation of traffic upon State highways in any way for which the approval of the Department of Transportation of the State is required by State law shall cease to be operative six (6) months after the receipt by the County Director of Public Works of written notice of withdrawal of approval by the Department of Transportation of the State.
   (e)   Whenever the provisions of this section delegate authority to a County officer or authorize action by the Board to regulate traffic upon a State highway which, by State law, requires the prior approval of the Department of Transportation of the State, no such officer shall exercise such authority, nor shall such action by the County Director of Public Works be effective, with respect to any State highway without the prior approval in writing of the Department of Transportation of the State when and to the extent required by Division 11 of the Vehicle Code of the State.
   (f)   The provisions of this section shall be of no force or effect unless the localities designated by resolution of the Board, as provided in subsection (b)of this section, are either plainly signposted or appropriately marked in the manner provided by Section 21351 of the Vehicle Code of the State to give warning of the prohibition of such parking. Such signs shall give notice of removal. (§ 1, Ord. 872, eff. April 1, 1980)
