(a) It shall be unlawful for any person to drive, or cause to be driven, any vehicle, including a motor vehicle, on or over any curb, sidewalk or drainage structure, except as provided in subsection (b) of this section and over driveways constructed for such purposes; provided, that this section shall not apply in emergencies where suitable provision is made, by the laying of planking or otherwise, for the bridging of such curb, sidewalk or drainage structure in such a way that no damage will be done thereto.
(b) Bicycles which are not motorized and special vehicles used by handicapped persons may be operated upon sidewalk areas and appurtenant drainage structures designed for pedestrian use except where, in the judgment of the county executive, it is necessary for the safety or control of vehicular and pedestrian traffic to prohibit riding of such vehicles. Whenever any person is riding upon a sidewalk, such person shall give an audible signal and yield the right-of-way to any pedestrian. The county executive may, by regulation adopted under method (3) of section 2A-15 of this Code, define "special vehicle" and "handicapped;" establish licensing requirements; and establish hours during which special vehicles may be operated upon sidewalk areas.
(c) The county executive shall provide for the erection of such traffic-control signs on sidewalk areas or bikeways as may be necessary to ensure the safety of bicyclists, pedestrians and operators of motor vehicles; provided that no sign shall be erected on state highways without the approval of the state highway administration.
