Vermont proposes regulations for motorcycle exhaust noise and emissions standards

On February 11, 2025, the Vermont State Legislature introduced Senate Bill 66, aimed at regulating noise pollution and emissions from motor vehicles and motorcycles. The bill seeks to address growing concerns over excessive noise and environmental impact caused by modified exhaust systems.

Key provisions of Senate Bill 66 include a prohibition on the use of certain muffling devices, gutted mufflers, and modifications that amplify vehicle noise. Specifically, it mandates that motorcycles manufactured after December 31, 1985, must comply with federal noise regulations and be equipped with appropriate mufflers. Additionally, the bill prohibits operating vehicles with modified exhaust systems that increase emissions of fumes or smoke.

The legislation allows for exceptions during authorized public exhibitions, such as races or contests, where modified vehicles may be operated legally. However, vehicles that do not meet the outlined standards will fail mandatory inspections, reinforcing compliance with the new regulations.

Debate surrounding Senate Bill 66 has highlighted concerns from various stakeholders. Proponents argue that the bill is essential for public health and environmental protection, while opponents raise issues regarding the potential economic impact on vehicle enthusiasts and businesses that modify vehicles. Some critics also question the feasibility of enforcing the new regulations.

The implications of this bill are significant, as it aims to reduce noise pollution and improve air quality in Vermont. Experts suggest that if passed, the legislation could lead to a cultural shift in vehicle modification practices, encouraging more environmentally friendly and quieter alternatives.

As the legislative process unfolds, Senate Bill 66 will likely continue to spark discussions on balancing individual freedoms with community health and environmental responsibilities. The next steps will involve committee reviews and potential amendments before a final vote is scheduled.
