   (a)    No operator of a vehicle shall stop, stand or park any vehicle upon a street, other than an alley, in such a manner or under such conditions as to leave available less than ten feet of the width of the roadway for free movement of vehicular traffic, except that an operator may stop temporarily during the actual loading or unloading of passengers or when necessary in obedience to traffic regulations or traffic signs or signals of a police officer.
   (b)   No operator shall park a vehicle within an alley in such a manner or under such conditions as to leave available less than ten feet of the width of the roadway for the free movement of vehicular traffic.
   (c)    No vehicle shall be parked upon any street which is not more than sixteen feet from curb to curb. Upon streets from sixteen to twenty-eight feet, parking shall be permitted on one side only; upon any streets in excess of twenty-eight feet, parking shall be permitted upon both sides. When parking is limited to one side of the street, the Director of Public Safety shall designate the side upon which parking is permitted and shall properly mark the same.
   (d)   On narrow streets, signs may be placed by the Director within a reasonable distance of the edge of the roadway or curb as he may designate, facing oncoming traffic, and on the side of the street where such sign is placed. No person shall stop, stand or park any vehicle along the edge of such roadway or curb within a distance of twenty feet in both directions from such sign, measured from a point on the edge of the roadway or curb at right angles to such sign.
