The purpose of this legislative text is to change the Clean Air Act by removing the requirement for states to have mandatory vehicle inspection and maintenance programs. This is aimed at giving states more flexibility in how they manage vehicle emissions and air quality. The key provisions of this legislation include the repeal of specific sections of the Clean Air Act that currently mandate states to implement vehicle inspection and maintenance programs. This means that states will no longer be required to conduct regular inspections of vehicles to ensure they meet emissions standards.
