What is a Test-Only Smog Stations role?
Test-Only Smog Stations provided non-biased Smog Checks for most vehicles. Since Test-Only Stations are not allowed to conduct emission repairs, there is no incentive to fail vehicles for the purpose of offering fraudulent repairs. The addition of Test-Only Stations to the Smog Check program augments a service previously provided on a temporary basis by state-contracted Referee Centers. Now, owners of gross-polluting vehicles must have their vehicles tested and certified at either a Test-Only Station or a Gold Shield Gross Polluter Certification Pilot station.
