Smog Check Program
Important! The BAR On-Board Diagnostic Inspection System (BAR-OIS) software has been rebranded the California Vehicle Inspection System (Cal-VIS). Cal-VIS will support both Smog Check inspections and, upon implementation of the Vehicle Safety Systems Inspection Program later this year, vehicle safety systems inspections.
The Cal-VIS rebrand will begin with the 23.3 server version update that will roll out to stations beginning January 8, 2024.
