(a) It shall be unlawful to stand or park any vehicle, except for a motorcycle or motor scooter, in a roadway other than parallel with the edge of the roadway headed in the direction of lawful traffic movement and with the curbside wheels of the vehicle within 12 inches of the curb or edge of the roadway; provided, however, this prohibition shall not apply to the parking of any vehicle in a designated diagonal parking zone or space.
(b) It shall be unlawful to stand or park any vehicle upon any street in such a manner or under such conditions as to leave available less than 18 feet of the width of the roadway for free movement of vehicular traffic on a two-way street or less than ten feet of the width of the roadway for free movement of vehicular traffic on a one-way street.
(c) It shall be unlawful to park any motorcycle or motor scooter other than perpendicular (meaning at a 90-degree angle) to the curb or edge of the roadway; provided, however, if such perpendicular parking of a motorcycle or motor scooter would violate subsection (b) of this section, then such motorcycle or motor scooter shall be parked diagonally within the pavement markings, at an angle that is as close as possible to a 90-degree angle to the curb or edge of the roadway while still complying with subsection (b) of this section.
