What Is a Gross Polluter Smog Check?
A Gross Polluter Smog Check is an emissions inspection required for certain vehicles that have been identified as producing higher-than-allowed emissions levels or have been selected for additional emissions compliance testing.
These vehicles may require testing at a STAR Certified station as part of California’s emissions control program.
The purpose of the program is to identify vehicles that may be contributing excessive emissions and ensure compliance with California air quality standards.
Why Was My Vehicle Selected?
Vehicles may be directed to enhanced emissions testing for several reasons.
- Previous emissions test results
- Vehicle emissions history
- DMV or Bureau of Automotive Repair requirements
- Directed Vehicle Program selection
- Registration renewal requirements
If your DMV notice requires a STAR inspection or enhanced emissions testing, KWIC Smog Center can perform the required inspection.
What Happens During the Inspection?
The inspection process is designed to verify that your vehicle’s emissions systems are operating correctly and that the vehicle complies with California emissions standards.
Our certified technicians follow California Bureau of Automotive Repair testing procedures and electronically report the results directly to the DMV.
