MICHIGAN -- Michigan could be making some changes on the state's mandatory helmet law.

The state house voted 69 to 39 to lift the legislation. If approved, the bill would allow motorcyclists 21 and older to ride without a helmet.

That's only if they meet specific safety and insurance restrictions. The change could mean big business for the state and its motorcycle shops.

"We may see more influx with possibly motorcycle rallies,” says Jennifer Loberman of MotorCity Harley-Davidson. "That has always been a big deterrent for Michigan having a successful motorcycle rally or a motorcycle week is our helmet law."

The change is not official just yet. If the senate approves the measure, it would then go to Governor Snyder for final approval.
