The actual test assesses three elements on the vehicle:
* Smoke puffing from the tailpipe or other areas of the auto.
* The effectiveness of the catalytic converter, which is the essential module in controlling pollution.
* A computerized gas analysis measured via the exhaust pipe while the vehicle is idling and at high speed.
All vehicles manufactured after the year 1975 are subject to the test. Those oldies made between 1975 and 1986 need to undergo the test on an annual basis. If you own a car or truck built after 1986, then you can stick to an every-other-year cycle.
