- AB 42 exempted vehicles manufactured before 1974 from smog check testing. Also required that vehicles 30 years old or older be exempt from the Smog Check program starting in 2004. AB 42 established a brief rolling chassis exemption until it was repealed in 2006 where 1976 and newer vehicles were subjected to emission testing.
