California Code, Health and Safety Code - HSC § 44000.5

(a) The Legislature further finds and declares that the motor vehicle inspection and maintenance program implemented under this chapter has, since 1984, provided beneficial emission reductions without undue inconvenience to California vehicle owners, and vehicle owners will benefit from the maintenance by the state of a substantially decentralized program giving them a choice among thousands of independent licensed stations able to perform both inspection and repair of vehicles.

(b) With the enactment of this chapter, the Legislature does not intend to create a statutory presumption that any motor vehicle, solely by virtue of make, model, or year of manufacture, shall be classified or categorized as a “gross polluter” or a “gross polluting vehicle.”
