(b) The Department with respect to highways under its jurisdiction or for the maintenance of which it is responsible may place signs prohibiting or restricting the stopping, standing or parking of vehicles on any highway where in its opinion such stopping, standing or parking is dangerous to those using the highway or where the stopping, standing or parking of vehicles would unduly interfere with the free movement of traffic thereon. Any such regulations adopted by the Department regarding the stopping, standing or parking of vehicles upon any specific street, streets or highways become effective at the time of the erection of appropriate signs indicating such regulations. Any such signs may be erected either by the Department or by a local authority with the approval of the Department.

The vehicle, in addition to having its hazard lights lighted at all times that it is engaged in stopping or standing, shall also use its amber oscillating, rotating, or flashing light or lights as authorized under paragraph 12 of subsection (b) of Section 12-215, if so equipped.
