LANSING, Mich. -

The latest attempt by Michigan lawmakers to repeal the state's law requiring use of helmets by motorcycle riders has passed the state House.

The measure approved by a 69-39 vote Wednesday returns to the Senate. If the Senate approves the House-backed changes, the legislation would be sent to Gov. Rick Snyder.

It's unclear what Snyder will do if the bill reaches his desk. The bill would allow riders 21 or older to go without helmets if they meet certain insurance and experience conditions.

The Legislature has passed bills to repeal the state's mandatory motorcycle helmet law before, but the bills were vetoed twice by then-Gov. Jennifer Granholm.
