This Act and other applicable laws of this State govern the operation, equipment, numbering and all other matters relating thereto whenever any snowmobile is operated within this State; but this Act does not prevent the adoption of any ordinance or local law by any political subdivision of the State relating to the operation and equipment of snowmobiles which is not inconsistent with this Act, amendments hereto or regulations issued hereunder. Such ordinances or local laws shall be operative only so long as they continue to be not inconsistent with this Act, amendments hereto or regulations issued hereunder. However, this Act is not a limit upon any home rule unit.
