Sounds and noise

Vermont sound ordinances include: Sound systems

  • It is unlawful to make unreasonable noise between sunset and sunrise. What constitutes unreasonable noise is that which annoys or disturbs others.

Mufflers

  • All vehicles must have mufflers that prevent unusual or excessive noise.

Tip: Always check with local county laws in Vermont to make sure you are following any municipal noise ordinances that may be more stringent than state-level laws.

Frame and suspension

Vermont does not have regulations on frame, suspension lift or bumper height limits.

  • Vehicles can be no taller than 13 feet 6 inches.

Engine

Vermont does not require emissions testing and does not list any engine modification or swap regulations.

Lights

  • After-market lamps must have “DOT” stamped on the lens if used on the roadways.
  • No undercarriage or glow lights are permitted.
