Gov. Snyder signed a helmet law repeal bill on Thursday making Michigan the 31st state with an optional helmet law.
Motorcyclists can forgo a helmet if they are at least 21 years old, carry at least an additional $20,000 in medical insurance and have either passed a motorcycle safety course or had their motorcycle endorsement for at least two years. Passengers also must be 21 or older to go helmetless, and there has to be an additional $20,000 in insurance for the passenger, bought either by the passenger or the motorcycle driver.
