To pass the visual inspection, the required emissions control systems must be...

• A. Complete and installed in accordance with the vehicle manufacturer's original CA or Federal certified configuration, or with CARB aftermarket configuration
• B. The vehicle passes if all components are OEM
• C. Only the visible parts must be present
• D. The inspection requires a written documentation from the manufacturer

Answer: (A)

The key idea is that the visual inspection checks that the emissions control system is complete and installed exactly as certified for the vehicle. To pass, everything required by the original California or Federal certification, or by CARB-approved aftermarket configuration, must be present and properly connected. This means no missing components and no improper modifications—the system has to match the certified setup for that model and year.

Even if parts are OEM, they must be installed in the correct configuration and be complete; simply having some components visible isn’t enough if others are missing or misinstalled. And the test relies on what’s physically installed, not on manufacturer documentation.
