The new 2012 Q&A pamphlet shows emission testing is required in 13 counties in Atlanta metro area for all cars and light duty trucks manufactured 1988 thru 2009. State law prohibits selling a car or light duty truck to anyone in these counties until it has passed a current year emission test. The vehicle for sale must have passed the test, it cannot be "emission test ready". If the current emission test certificate has been lost, go to www . CleanAirForce . com, input the VIN# and print the certificate.
