New York Consolidated Laws, Vehicle and Traffic Law - VAT § 1274. Riding on roadways, shoulders and lanes reserved for non-motorized vehicles and devices

1. Upon all roadways, any electric personal assistive mobility device shall be operated either on a usable bicycle or in-line skate lane or, if a usable bicycle or in-line skate lane has not been provided, near the right-hand curb or edge of the roadway or upon a usable right-hand shoulder in such a manner as to prevent undue interference with the flow of traffic except when preparing to enter into a crosswalk to turn left at or to cross an intersection or when reasonably necessary to avoid conditions that would make it unsafe to continue along near the right-hand curb or edge of the roadway.  Conditions to be taken into consideration include, but are not limited to, fixed or moving objects, vehicles, bicycles, in-line skaters, pedestrians, animals, surface hazards and traffic lanes too narrow for an electric personal assistive mobility device and a vehicle to travel safely side-by-side within the lane.

2. Persons operating electric personal assistive mobility devices upon a roadway shall ride single file.  Persons operating electric personal assistive mobility devices upon a shoulder, bicycle or in-line skate lane, or bicycle or in-line skate path, intended for the use of bicycles, electric personal assistive mobility devices or in-line skates may ride two or more abreast if sufficient space is available, except that when passing a vehicle, bicycle, electric personal assistive mobility device, person on in-line skates or pedestrian standing or proceeding along such shoulder, lane or path, persons operating electric personal assistive mobility devices shall operate such devices in single file.

3. Any person operating an electric personal assistive mobility device who is entering the roadway from a private road, driveway, alley or over a curb shall come to a full stop before entering the roadway.
