474.07   RIDING REGULATIONS.
   It shall be legal to ride a bicycle upon a sidewalk, street or public way, or upon any path set aside for the exclusive use of bicycles, except State, Federal or County highways, where sidewalks are available, subject to the following:
   (a)   Wherever a designated path for bicycles has been provided adjacent to a street, bicycle riders shall use such path and shall not use the street.
   (b)   Any person operating a bicycle may ride upon the sidewalk rather than the roadway when sidewalks are available and not congested with pedestrian traffic. If the sidewalk is congested with pedestrian traffic, the bicycle operator using the sidewalk shall walk the bicycle.
   (c)   No person shall ride a bicycle upon a sidewalk, upon or along which signs have been erected by authority of the Chief of Police prohibiting such bicycle riding.
   (d)   Whenever a person is riding a bicycle upon a sidewalk, street, roadway or any pedestrian way, such person shall yield the right-of-way to any pedestrian and shall give an audible signal before attempting to overtake and pass a pedestrian or another bicycle. This audible signal must be given only by a bell or other warning device capable of giving an audible signal, and shall be given at such a distance and in such a manner as not to startle any person being overtaken and passed.
   (e)   Whenever a person is riding a bicycle on a sidewalk, the rider shall dismount and shall walk the bicycle across an intersection or a street.
   (f)   Whenever a person is riding a bicycle upon a sidewalk, the person, before overtaking and passing a blind person carrying a white or metallic cane or guided by a dog, shall dismount and overtake or pass on foot.
   (g)   When a bicycle is operated on a street, the operator shall give hand signals before turning, changing lanes or stopping. Such signals shall conform to Section 432.14.
