SLCRO §716.078 bans operating an ATV on private property within 100 ft of another's residence or on any public paved road or sidewalk. Pocket bikes (≤49cc) are 'motor vehicles' subject to the county noise ordinance and require a driver's license and helmet.
The Disturbance of the Peace — ATV provision applies countywide to any three- or four-wheeled motorized vehicle designed for off-pavement use, with a 100-foot setback from neighboring residences and a complete ban on public paved roads and sidewalks. Pocket bikes (mini-motorcycles ≤49cc, max 30 mph) fall under SLCRO 1210.105 through 1217.010; operators must hold a valid driver's license, wear an approved helmet, and obey all traffic laws.
Citation, vehicle impoundment, and fines up to $1,000 per Municipal Court; repeated violations can lead to a permanent injunction against operating in the neighborhood.
