What Are Automobile Emission Regulations?
There are several federal and state laws governing automobile emissions. The Clean Air Act, a federal law, requires vehicle owners with cars manufactured in 1996 or later to have emissions checked with an onboard diagnostics test. If the car fails this emissions test, repairs must be performed to bring the vehicle into compliance with emissions standards. There are exceptions to this requirement, so check with your local DMV for the emissions regulations in your area.
