STAR program

The STAR program was created pursuant to Assembly Bill 2289 (Eng, Chapter 258, Statutes of 2010) to improve the overall quality of Smog Check inspections and help the state meet required emissions reductions. The program offers voluntary certification of Smog Check test-and-repair and test-only stations that must adhere to high inspection-based standards.
