The bill enacts R.S. 39:364.1, which aims to preserve the freedom of choice for individuals in selecting combustion engine vehicles. It defines a "combustion engine vehicle" as one that converts chemical energy in fuel into mechanical energy for power. The legislation prohibits state agencies from restricting the use or sale of motor vehicles based on their energy source, ensuring that citizens can purchase vehicles without limitations related to propulsion energy or other functions.

Additionally, the bill explicitly states that no state agency can limit or prohibit the sale of new motor vehicles with internal combustion engines. It also clarifies that any air quality challenges associated with Louisiana's Toxic Air Pollutant Emission Control Program will not impede citizens' ability to buy any vehicle. This legislation reinforces the right of Louisiana residents to choose their vehicles without interference from state regulations concerning air quality.
