Beginning July 1 2015, all snowmobiles operating on public trails in Wisconsin must display a trail pass. This is separate from the registration sticker. Registration stickers are now good for three years. The trail pass sticker must be purchased annually.
If you are a Wisconsin resident and a member of a snowmobile club that is part of the AWSC, then you can get a discounted trail pass for only $10. For Wisconsin residents that are not a member of an AWSC snowmobile club, the cost is $30. For non-residents, the cost is $50. The trail pass sticker is to be mounted to the bottom center portion of the windshield.
