If your car is exempt, either you or the auto dealer will need to complete form MV-74 to certify the exemption.
I'm thinking about buying another car. How do I know if the car I buy complies with the California emissions standard?
You can find this information on the MCO. There should also be an emissions label under the car's hood with this information.
My car is a 2002. Is it subject to the California emissions standards?
