California law mandates that certain vehicles be inspected at a Star Certified Smog Check Inspection Station because they meet performance standards that are more stringent than stations who are not Star Certified. These vehicles are called directed vehicle and the definition of a directed vehicle is outlined below:

A “Directed vehicle” is a vehicle required by the State of California to have its Smog Inspection performed at a smog station meeting certain performance standards. These standards were enacted and are titled under the  STAR Program. Stations meeting specific standards are certified by theDepartment of Consumer Affairs Bureau of Automotive Repair (BAR) and are authorized to inspect directed vehicles.

How does the state of California determine which vehicles are directed?

The State of California mandates that a certain percentage of the vehicles registered with the California DMV undergo smog testing at Star Certified Stations. Additionally, vehicles with high emitter profiles fall in to the directed vehicle status, as well. These are vehicles which fail smog inspection or on the lower end of passing the smog check. The last category of vehicles that must undergo a smog check at a Star Station is the gross polluter. These vehicles are ones that failed the smog check and the pollution that is emitted from the tail pipe exceed normal smog check failure standards.
