Can a vehicle pass inspection with a "check engine" light illuminated?

A vehicle cannot pass inspection if the "check engine" light is illuminated. This is because the light often indicates that there is an underlying issue with the vehicle's onboard diagnostic system, which monitors emissions and engine performance. In the context of state inspections, a illuminated "check engine" light is a clear indication that there may be a failure in compliance with emissions standards or other significant operational issues that need to be addressed.

Passing inspection requires that the vehicle meets all specified safety and emissions standards, and an illuminated "check engine" light typically suggests that the vehicle may not meet those standards. Inspectors are trained to identify this as a critical issue, preventing the vehicle from being certified as safe or compliant. This is particularly concerning in emissions testing, where failures related to the "check engine" light can lead to further regulatory and environmental implications.

The other options do not accurately reflect the standard policy surrounding the "check engine" light. Minor issues, additional checks, or relating the light to emissions only do not amend the fundamental fact that the vehicle will fail inspection if this light is on at the time of the inspection.
