This bill, known as the State Emissions Authority Act of 2026 , aims to eliminate federal mandates for state motor vehicle inspection and maintenance programs. It specifically amends various sections of the Clean Air Act to repeal the mandatory requirements that currently compel states to implement these emissions testing programs. By striking specific subsections and paragraphs within sections 118, 182, 184, and 187 of the Clean Air Act, the legislation removes the federal obligation for states to conduct vehicle inspections and maintenance. This legislative action would effectively transfer authority over such programs back to individual states, allowing them to decide whether to establish or continue their own vehicle emissions control initiatives.
