Whenever, by this article or any other ordinance of this City, any parking time limit is imposed or parking is prohibited on designated streets, no such regulations shall be effective unless appropriate signs giving notice thereof are erected and in place at the time of any alleged offense, except that no such signs need be erected to make effective ordinances regulating the stopping, standing or parking of vehicles when these ordinances do not differ from the provisions of Act No. 300, Public Acts of 1949, as amended. Further, there shall be no requirement for the posting of signs prohibiting commercial vehicles from being parked or stored on residentially zoned property.
