The new STAR Program begins January 1, 2013, and will replace the Gold Shield and Test Only program. If your DMV registration renewal notice states your vehicle requires a smog check at a STAR station, you may still take your vehicle to a Gold Shield or Test Only station before the new program begins.  If your vehicle registration states your vehicle requires a smog check at a Gold Shield or Test Only station, you must take your vehicle to a STAR station after December 31, 2012.
