Or cut out the section of window that has the sticker on it. Cut it large enough so you can drill a hole to mount it in one of the shield screws. Also what was stated above they will replace the sticker for a few dollars.
Which is why I don't put the sticker on the windshield.
According to the Michigan DNR site the sticker "must" be permantly affixed to the sled. screws can be removed. Removing the sticker will bring a void embedded message to be seen, thus voiding the trail permit. You want to see a grown person cry. I lost a windshield a few yrs. back. Canada permit was $230, Michigan permit was $25, Wyoming permit was $25. windshield was $90.
In michigan do you always have to put the sticker on your windshield i have been putting my wyoming non resident stickers on my tunnels and never had a problem
I just place mine on my helment so I'm always covered.
