Smog Check in California Exempted Vehicles

Just about everything in California gets a smog check every two years. That includes gasoline, propane, ethanol, and natural gas powered vehicles. There are areas in California that don't get biennial smog checks, but most areas where people live, they are a requirement. Cars that are 1975 or older, and diesel vehicles 1997 or older don't get smog checks.
