Each city may regulate the transportation by motor-vehicles (not operated on tracks) of passengers or property, for pay, within the limits of the city, or from points in the city to points beyond the limits of the city. In such regulations the city may impose reasonable license fees, make regulations for the operation of vehicles, the rates to be charged for transportation and may designate certain streets upon which such vehicles, if operated, must be operated.
