No driver of a two- or three-wheel motor vehicle shall carry any other person on,
upon or within such vehicle on any street or highway, except as hereinafter provided.
If a two- or three-wheel motor vehicle with a wheel diameter of 12 inches or greater
shall have either a double seating device with double foot rests, or a side car attachment
providing a separate seat space within such side car attachment for each person riding
therein so that such person shall be seated entirely in the body of said side car,
then it shall be permissible for an operator who attained the age of 16 or older to
carry a passenger. A demonstration ride by a licensed dealer or his employee is excepted
from the provisions hereof.
