Nooooo, each state has criteria for emissions inspection.....but Chevy started emissions controls in 1967 (for states other than CalEfornia) which is why a 1966 Nova is more desirable in certain states than a 1967 Nova is.

You have to research individual states to find the answer. Some states require emissions testing based upon city or county of residence...for instance, in Arizona, certain counties require emissions while others do not.

Try google.com It may have some answers.
