Kevin asked: I know that there are some areas (usually city centers/downtown) that ban bicycle riding on sidewalks altogether but have been having trouble finding local laws concerning bicycle riding. Is it legal to ride a bicycle on sidewalks in downtown Fort Lauderdale?
Unless there is a local ordinance to the contrary, it is legal to ride on sidewalks.
s. 316.2065 – Bicycle Regulations
(9) A person propelling a vehicle by human power upon and along a sidewalk, or across a roadway upon and along a crosswalk, has all the rights and duties applicable to a pedestrian under the same circumstances.
(10) A person propelling a bicycle upon and along a sidewalk, or across a roadway upon and along a crosswalk, shall yield the right-of-way to any pedestrian and shall give an audible signal before overtaking and passing such pedestrian.
I can find no such prohibition in Broward County.
There are certain restrictions in the City of Fort Lauderdale, most notably these,
Sec. 26-182. – Riding on city property.
(a) No person shall ride a bicycle or skateboard or rollerskate or in-line skate upon a sidewalk or any city property where signs are erected prohibiting such activity. The areas where such activities are prohibited shall be designated by resolution of the city commission, and such areas shall be posted accordingly.
Also note that city residents must register bicycles.
Sec. 26-183. – Bicycle registration.
(c) It shall be the duty of any person residing within the city who owns any bicycle to register such bicycle with the police department in accordance with the provisions of this section.
