(A) It shall be unlawful for any person to move or operate heavy equipment across any curb, gutter, bridge, culvert, sidewalk, crosswalk or crossing on any unpaved street without first having protected such curb, gutter, bridge, culvert, sidewalks, crosswalk or crossing with heavy plank sufficient in strength to warrant against the breaking or damaging of such curb, gutter, bridge, culvert, sidewalk, crosswalk or crossing.
(B) It shall be unlawful to run, drive, move, operate or convey over or across any paved street a vehicle, machine or implement with sharp discs or sharp wheels that bear upon the pavement; with wheels having cutting edges; with wheels having lugs, any protruding parts or bolts thereon that extend beyond a plain tire so as to cut, mark, mar, indent or otherwise injure or damage any pavement, gutter or curb, except that where heavy vehicles, structures and machines move along paved or unpaved streets, the city police are authorized and empowered to choose the route over which the moving of such vehicles, structures or machines will be permitted and allowed. This prohibition shall not apply to pneumatic tires with metal or metal-type studs not exceeding five-sixteenths of an inch in diameter, inclusive of the stud-casing with an average protrusion beyond the tread surface of not more than seven sixty-fourths of an inch between November 1 and April 1, except that school buses, mail carrier vehicles and emergency vehicles shall be permitted to use metal or metal-type studs at any time during the year.
