For a government fleet vehicle that fails as a gross polluter, which testing location is authorized to certify?

• A. STAR station only
• B. Any certified test station
• C. Mobile testing unit only
• D. Out-of-state facility

Answer: (A)

When a vehicle is flagged as a gross polluter, only STAR-certified testing stations have the authority to re-test and certify it after repairs. These stations are equipped to perform the enhanced procedures needed to verify that the emissions problem was truly corrected and that the vehicle now meets the required standards. This safeguard ensures the high-emitting issue is resolved before the vehicle returns to the normal testing cycle. Other options aren’t authorized for this certification step: non-STAR stations, mobile units, or facilities out of state don’t have the approval to certify gross polluter repairs under California’s Smog Check rules.
