Nicodemus asked: Let’s say I have my moped, and I turn off both the gas motor AND the electric motor, meaning the vehicle is now propelled exclusively by human power. Now is my moped allowed on the sidewalk/bike path?
Sidewalks are for the use of pedestrians.
s. 316.003 – Definitions
(47) Sidewalk—That portion of a street between the curbline, or the lateral line, of a roadway and the adjacent property lines, intended for use by pedestrians.
Persons operating human powered vehicles may use a sidewalk unless prohibited by local ordinance.
s. 316.2065 – Bicycle Regulations
(9) A person propelling a vehicle by human power upon and along a sidewalk …. has all the rights and duties applicable to a pedestrian under the same circumstances.
Bicycle paths are roadways open for the use of bicyclists and are frequently used by pedestrians.
(63) Bicycle Path – Any road, path, or way that is open to bicycle travel, which road, path, or way is physically separated from motorized vehicular traffic by an open space or by a barrier and is located either within the highway right-of-way or within an independent right-of-way.
Except for a few limited exceptions, such as motorized wheelchairs, vehicles on sidewalks and bike paths may be propelled only by human power.
s. 316.1995 – Driving Upon Sidewalk or Bicycle Path
(1) …. a person may not drive any vehicle other than by human power upon a bicycle path, sidewalk, or sidewalk area ….
Seemingly, the only restriction to use of your vehicle on a sidewalk or bike path is that it must be propelled only by human power.
