Bill S.66 aims to regulate noise levels from motor vehicles, prohibit certain exhaust system modifications, and set requirements for engine compression brake devices. The bill introduces new provisions that establish specific sound limits for motor vehicles based on their weight and speed, with penalties for violations ranging from $100 to $350 for first, second, and subsequent offenses. Additionally, it prohibits the operation of vehicles with modified exhaust systems that emit excessive noise or smoke, and mandates that engine compression brake devices be used only with appropriate mufflers to mitigate noise.

The bill also includes a provision for the establishment of a motor vehicle noise reporting system by the Agency of Transportation, allowing citizens to report vehicles that may be in violation of the new noise regulations. The penalties collected from violations will be directed to the Transportation Fund to support enforcement efforts. The act is set to take effect on July 1, 2025.
