A. No person shall park a vehicle in any alley in the central traffic district, or in any business district, between the hours of eight a.m. and six p.m. of any day except Sunday; provided, however, this prohibition shall not apply to a commercial vehicle which is registered as such by the Department of Motor Vehicles, which is being used primarily for delivery, or any vehicle being used primarily for delivery in a business or by a certified carrier where the name of such business is painted on or permanently attached to both sides of the vehicle or the P.U.C. certificate or Cal T number is plainly shown on both sides or front and rear of the vehicle.

B. No person shall park any of the excepted vehicles specified in subsection A for a time longer than one hour in an alley which is within the central traffic district, or in any business district, between the hours of eight a.m. and six p.m. of any day except Sunday.

C. The traffic authority is authorized to prohibit the stopping, standing, or parking of vehicles on one side of an alley, provided curbs are painted or appropriate signs are placed and maintained to give notice thereof.

D. The traffic authority is authorized to make studies and surveys to determine whether or not parking may be permitted in certain alleys within the city. In making these surveys, the traffic authority shall consider the width of the alleys, whether or not the parking of private passenger vehicles within the alley would impede the traffic within the alley. Where the traffic authority finds as a result of its survey and study that it is reasonable to permit parking in an alley and that the public convenience would best be served by permitting parking in an alley, the traffic authority is authorized to designate the alleys or portions thereof for parking. Where the traffic authority has made such a survey and has made a determination that the public convenience would best be served by permitting private passenger vehicles to park in certain alleys and has therewith designated certain alleys or portions thereof for parking, subsections A and B of this section shall not apply.
