What is 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 gold shield gross polluter certification pilot station.

Why is my car being tested on new smog equipment?
the new equipment and the new test, which is performed under simulated driving conditions, is required by state law in the state’s smoggiest regions (enhanced areas) in order to meet federal clean air standards. the new equipment tests for oxides of nitrogen (nox), an important smog-causing compound. the old equipment did not test for nox.

For how long is a smog check certificate valid?
a smog check certificate of compliance or non-compliance is valid for 90 days.

Who is responsible for obtaining a smog check when a vehicle is sold?
it is the responsibility of the seller to provide a valid smog certificate at the time of delivery of the vehicle. there is no provision in the law to sell a vehicle “as is.”
