(a) 
No person shall place, maintain or display upon or in view of any road, street or highway any unauthorized sign, signal, marking or device which purports to be or is an imitation of or resembles an official traffic-control device or railroad sign or signal, or which attempts to direct the movement of traffic, or which hides from view or interferes with the effectiveness of any official traffic-control device or any railroad signal or sign, and no person shall place or maintain nor shall any public authority permit upon any highway or street any traffic signal or sign bearing thereon any commercial advertising.
