Vermont S0066 regulates motor vehicle noise, exhaust modifications, and engine compression brakes.

Vermont S0066 establishes noise limits for motor vehicles and prohibits modifications that increase noise or smoke emissions. It mandates that vehicles with a gross weight rating over 10,000 pounds must not exceed 80 decibels at 35 miles per hour or less and 87 decibels at speeds over 35 miles per hour. Vehicles under 10,000 pounds must not exceed 72 decibels at 35 miles per hour or less and 80 decibels at speeds over 35 miles per hour. The bill also requires engine compression brakes on trucks and truck tractors to be equipped with mufflers to prevent excessive noise.
