AN ACT CONCERNING NOISE POLLUTION.

This bill establishes a pilot program to test solar-powered noise barriers along state highways, aiming to reduce traffic noise while generating electricity. It requires the state transportation commissioner to install and evaluate one to three of these structures, consulting with utility regulators on power connections, and submit a detailed report by January 2028 on costs, performance, and environmental impacts. The legislation also updates vehicle noise regulations by reinforcing requirements for mufflers, exhaust systems, and horns, while increasing the fine for violations to $150,000 per offense. These changes directly affect state highway infrastructure projects and motor vehicle owners and operators.
