Children's Life Jackets - Michigan
All children in Michigan, under the age of 6, are required to wear a U.S. Coast Guard approved life jacket or life vest when onboard a boat.
The life vest should always be in good condition and fit the child properly. The exception to this rule is when the child is below deck.
Ultimately it is up to the Parents, who are responsible for keeping their children protected by requiring them to wear life jackets. The USCG and your boat insurance company will expect everyone to comply with the state boating safety regulations.
