How can I remove my insurance sticker from my license plate withoute cracking it or damaging it?

How can i remove it and keep it intact in one peice?

What state do you live in?? I'm not sure if every state is the same, but in Illinois we have a small sticker that's good for (I think) a year - it is the registration sticker...it has a date on it (like 07/07. Is this the sticker you're referring to?? I've not heard of an insurance sticker. If it's the "registration" type, you can just put the new one over the old one. However, if that's not it, please describe why you 'need' to remove it.
