What the law says
Vermont law is qualitative rather than numeric: A muffler in good working order is required, exhaust may not produce excessive or unusual noise, and cutouts or bypasses are prohibited. Vermont enforces exhaust condition through its general 'properly equipped' requirement plus annual inspection. 66, which would have added statewide noise limits and an exhaust-modification ban, passed the Senate but died in House Transportation on May 29, 2026 — Vermont law is unchanged.
