How are vehicles selected for STAR smog check?
The State of California uses the following three strategies to determine whether a vehicle is STAR station designated or not:
- Gross polluters (vehicles which have failed a previous smog inspection with very high emission readings)
- High Emitter Profile vehicles. These are vehicle types designated by the Bureau of Automotive Repair as having high chances of failing the smog inspection.
- A random sample of all vehicles registered in California and being driven on public roadways.
