Why a Test-Only Smog Check?
The Test-Only Stations' Role: 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 GPC station.
Additionally, under mandate, 30% of vehicles in Enhanced Areas must be inspected at Test-Only
Stations for SmogCheck. DMV informs motorists of this requirement through the renewal notice. All Test-Only directed
consumers are eligible for repair and retirement assistance.
