Los Angeles Municipal Code § 62.94 Protection of Sidewalks

No person shall drive any wagon or any other vehicle over, along or across any cement or other improved sidewalk or curb, unless planking is laid thereon in such a manner as to protect such sidewalk or curb. No person shall remove any such planking, except the person by, or for whom it was laid, unless permission therefor is granted by the Board. Provided, however, that the provisions of this section shall not apply to the driving of vehicles over sidewalks and curbs, at places where cement or asphalt crossings are constructed across such sidewalks or curbs.

No person shall operate upon, or permit to be on or operated upon the improved portion of any concrete, asphalt, rock and oil, or oiled street or public way in the City of Los Angeles any vehicle having thereon a tire or tires, on the periphery of which there is or are any block, stud, flange, cleat, ridge, bead or any other protuberance of metal or wood which projects beyond the tread of the traction surface of the tire. This section shall not prohibit the use of tire chains of reasonable size to prevent skidding when upon wet or slippery surfaces, nor shall the restrictions of this section apply to such a vehicle when its operation on any street or road is necessary in the construction or repair thereof.
