STAR stations are used to administer the Smog test for which vehicles?

• A. New vehicles.
• B. High Emitter Profile vehicles.
• C. Diesel vehicles only.
• D. Low-emission vehicle tests.

Answer: (B)

STAR stations are set up to handle vehicles that are most likely to emit higher levels of pollutants—the High Emitter Profile vehicles. In California’s Smog Check program, certain vehicles are identified as higher risk for excessive emissions and are routed to STAR-certified stations to ensure their emissions are measured and verified more rigorously. This targeted approach helps catch and correct problems in vehicles that would contribute more to air pollution if left unchecked.

New vehicles aren’t singled out for STAR testing specifically, and diesel vehicles follow their own testing paths. Low-emission vehicles aren’t the focus of STAR testing either. The emphasis of STAR is on those vehicles that historically show higher emission tendencies.
