I'd leave the stickers on except for the ones on the lower part of the windshield (v-opt style?

). People may not be a fan of them but the other stickers you have around your car aren't illegal. A cop tried to tell me that any stickers on Windows (even those on the back) warrants a $230 fine. Looked it up, no such law exists. H8rs B H8in
