ยง 2226. Licensing by municipalities. No municipality shall require
licensing or registration of snowmobiles which are covered by the
provisions of this article; nor shall it require possession of a valid
motor vehicle operator's license as a condition for the operation of a
snowmobile on lands owned or controlled by such municipality. Nothing
herein shall prohibit the requirement of a permit by the agency having
jurisdiction over any state or local park for use of snowmobiles on such
park lands. No charge for such use may be made, except the usual charge,
if any, for admission to such park, parking privileges or services
provided.
