The California Smog Check Program was initially implemented in 1984 to reduce air pollution in California by ensuring that vehicles are repaired in accordance with state and federal requirements. The program subjects vehicles to a biennial inspection to ensure that they meet the guidelines set by the state. There are some exemptions from the Smog Check program. Gasoline vehicles less than 6 years old are exempt from the program (4 model years for change of ownership) unless the vehicle is coming to California from out of states. 1975 and older gasoline vehicles are also exempt from this program. 1998 and newer diesel vehicles weighing more than 14,000 GVWR does not require a biennial smog inspection as well as 97 and older diesels.
