careful with all those stickers in your windows boys.. the fines are gonna come the moment you over do it, and some Metros will even fine for a Baby on board sticker etc .
Read:
Section 202(3)(c) of the National Road traffic act, which reads:
3) No person shall operate on a public road any motor vehicle –
c) if, after 1 January 2000, any material or film, with a textured, displaying a picture or graphics is applied to the rear window that covers more than one-sixteenth of such rear window, or windscreen or side window.
Don't say you haven't been warned.
