Slow Down, Don't Drink and Live to Enjoy Michigan's Winter Wonderland. The State of Michigan, including every available branch of law enforcement, thoroughly enforces all snowmobile laws.
Fines are substantial.
A snowmobile is any motor driven vehicle designed primarily for travel on snow or ice utilizing sled type runners or skis, or an endless belt tread or similar means to contact the surface upon which it is operated. A snowmobile shall not be operated by a Michigan resident unless the owner first obtains a certificate of registration and a registration decal. A snowmobile owned by a non-resident, before operation in Michigan, must display a valid registration from their home state or province, or be registered in Michigan. The registration cycle begins on October 1 and expires on September 30 of the third year following registration. Any time a registered snowmobile is sold to another person, the registration must also be transferred.
