As of July 1, 2004, the metal traction device (stud) permit is no longer needed for snowmobiles registered in Minnesota.
However, you may not operate a snowmobile with metal traction devices on paved public trails, except when allowed by local government on trails under these jurisdictions or any portion of a paved state trail designated for such use by the commissioner.
