§ 71.11 TRUCK PARKING.
   (A)   Public property. It is unlawful to park a detached semi-trailer upon any street, city-owned parking lot, or other public property.
   (B)   Residential district. It is unlawful to park a semi-trailer, whether or not attached to a truck-tractor, within an area zoned as a residential district, except for the purpose of loading or unloading the same.
   (C)   Commercial vehicles greater than one-ton capacity. It is unlawful to park a commercial vehicle of more than one-ton capacity upon any street in the business district which has been duly sign-posted prohibiting the same, but parking of such vehicle for a period of not more than 30 minutes shall be permitted in such space for the purpose of necessary access to abutting property for loading or unloading when such access cannot reasonably be secured from an alley or from an adjacent street where truck parking is not so restricted.
   (D)   Diagonal parking prohibited. It is unlawful to park a truck or other vehicle using or equipped with a trailer, or extended body or other extension or projection beyond the original length of such vehicle, or any passenger bus, diagonally along any street except for a time sufficient to load or unload, and in such case, only parallel parking shall be permitted; provided, however, that a truck may stand backed up to the curb if the weight or bulk of the load makes parallel parking impracticable, but then only for a period of time sufficient to load or unload.
   (E)   Loading zones and alleys. Parking of commercial vehicles is permitted in duly designated and sign-posted loading zones, and in alleys, for a period of up to 20 minutes, all of which shall be for the purpose of access to abutting or adjacent property while actively loading or unloading.
