A: Smog test shops typically offer two types of smog checks: the biennial smog check and the change of ownership smog check. The biennial smog check is a comprehensive vehicle emissions test that is required in some states every two years for most gasoline-powered vehicles that are six or fewer model years old. The change of ownership smog check is a basic emissions test that is required whenever a vehicle changes ownership in certain states. This test is typically cheaper and is done to ensure that the new owner is not taking responsibility for an already-polluting vehicle.
