Michigan drivers who renew their registration would have to opt out to avoid paying an $11 fee that allows unlimited entry into state parks under a bill advancing in the Legislature.
Currently motorists must opt into paying the Recreation Passport fee when renewing their license plate annually.
The Republican-led Senate passed the bill on a 28-9 vote Thursday, sending it to the GOP-controlled House for consideration next week.
Supporters say switching to an opt-out participation model would generate more revenue to address a $260 million backlog in infrastructure needs in the state park system.
Nineteen Republicans and nine Democrats supported the measure, while seven Republicans and two Democrats opposed it.
