For 2007 and newer diesel powered vehicles, how many monitors can be incomplete?

None
One
Two
Three

The correct answer is: One

For diesel-powered vehicles from 2007 and newer, a maximum of one monitor can be incomplete for the vehicle to still pass the smog check. This standard is in place because newer diesel engines are equipped with advanced emissions controls and monitoring systems that are critical for ensuring compliance with the latest environmental regulations. If more than one monitor is found to be incomplete, the vehicle typically fails the inspection, as this may indicate significant issues with the vehicle's emissions system, which could lead to higher emissions than allowed by regulations. Therefore, allowing just one incomplete monitor ensures that the vehicle is still adequately compliant with emission standards while optimizing the inspection process. Having stricter limitations on incomplete monitors aligns with efforts to reduce pollution and improve air quality, reflecting California’s commitment to environmental protection.
