Section 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.
