What’s in it

This bill prohibits local authorities from issuing a citation for a violation detected by an automated vehicle noise enforcement system, as defined in the bill, based on noise emitted from the use of a vehicle’s brake or exhaust system while the vehicle is reducing speed. A citation issued in violation of the bill is void and unenforceable.
