<P> The California Smog Check Program requires vehicles that were manufactured in 1976 or later to participate in the biennial ( every two years ) smog check program in participating counties . The program 's stated aim is to reduce air pollution from vehicles by ensuring that cars with excessive emissions are repaired in accordance with federal and state guidelines . With some exceptions , gasoline - powered vehicles that are six years old or newer are not required to participate ; instead , these vehicles pay a smog abatement fee for the first 6 years in place of being required to pass a smog check . The six - year exception does not apply to nonresident ( previously registered out - of - state ) vehicles being registered in California for the first time , diesel vehicles 1998 model or newer and weighing 14,000 lbs or less , or specially constructed vehicles 1976 and newer . The program is a joint effort between the California Air Resources Board , the California Bureau of Automotive Repair , and the California Department of Motor Vehicles . </P>
