Transportation: authorities; public transportation authority millages; modify, and end the ability of political subdivisions to opt out of membership in public transportation authorities. Amends secs. 8, 18 & 29 of 1986 PA 196 (MCL 124.458 et seq.).

This bill modifies Michigan's Public Transportation Authority Act to change how local governments can leave these regional transit organizations. It removes the ability of cities, villages, or townships to simply vote to opt out of membership, requiring them to either pay off all financial debts or go through a public vote by registered electors to withdraw. Additionally, the legislation prevents local units from leaving an authority once they have already agreed to pay a specific tax, ensuring that financial commitments are honored even if the community later decides to exit the system.
