A. Except when necessary in obedience to traffic regulations or traffic signs or signals, it is unlawful to stop, stand or park such vehicle in a roadway other than parallel with the edge of the roadway, headed in the direction of traffic, and with the curbside wheels of the vehicle within twelve inches of the edge of the roadway, except as provided in subdivisions (1) and (2) of this subsection:
1. Upon those streets which have been marked or signed for angle parking, vehicles shall be parked at the angle to the curb indicated by such marks or signs.
2. In places where, and at hours when, stopping for the loading or unloading of merchandise or materials is permitted, vehicles used for the transportation of merchandise or materials may back into the curb to take on or discharge loads, when the owner of such vehicle holds a permit granting him such special privilege; and provided further, that such permit shall be either in the possession of the operator or on the vehicle at the time such vehicle is backed against the curb to take on or discharge a load, and it shall be unlawful for any owner or operator to violate any of the special terms or conditions of any such special permit.
B. The city council shall determine upon what streets angle parking shall be permitted, after an engineering study to determine feasibility, and shall cause the same to be marked or signed.
C. The police department is authorized to issue, to any owner of a vehicle used to transport merchandise or materials, a special permit, renewable annually, and to state therein the terms and conditions thereof, allowing the operator of such vehicle the privilege of loading and unloading while the vehicle is backed against the curb, if in the opinion of the police department such privilege is reasonably necessary in the conduct of the owner's business and will not seriously interfere with traffic.
