You can get them off with a hair dryer. Rub the leftover adhesive with a rag soaked in gasoline. Get the gasoline off with Dawn dish soap and water. Done.

That's the reason why the only bumper sticker that has graced any of my mother's cars is one I got in my first middle school for being an honor student.

I don't even know why she put it on in the first place. Woman goes apeshit if some asshat parks next to her and swings his door a little too close to her car...

Not if you put them on the back window. My friend makes me window stickers with her cricut.
