The bill H.48, introduced by Representatives Graning and Arsenault, aims to enhance air quality by prohibiting the installation of devices that increase a motor vehicle's ability to emit soot, smoke, or particulates. It amends existing laws to include new provisions that make it illegal to retrofit vehicles with such equipment and to operate vehicles that have modified exhaust systems designed to emit excessive pollutants. Violators of these provisions will face civil penalties, with fines ranging from $500 for a first offense to between $500 and $1,000 for subsequent offenses.

Additionally, the bill stipulates that any motor vehicle operated on public highways must be in good mechanical condition and properly equipped, reinforcing the requirement for vehicles to maintain their air pollution control systems. The new regulations will take effect on July 1, 2025, emphasizing the state's commitment to reducing vehicle emissions and improving air quality for its residents.
