What does a vehicle's "check engine" light indicate during an inspection?

• A. It is only a minor issue that can be ignored
• B. It may signify an emissions system issue that requires further evaluation
• C. It indicates that the vehicle is in good condition
• D. It has no relevance to the inspection

Answer: (B)

The "check engine" light serves as a crucial alert for the vehicle's onboard diagnostics system. When illuminated, it typically indicates that there may be an issue with the vehicle's emissions system or other critical functions that should be addressed. During an inspection, this warning light is significant because it urges further evaluation to determine the nature of the problem. Ignoring the "check engine" light can lead to more severe engine problems or increased emissions, which can hinder compliance with state regulations regarding vehicle safety and environmental standards. Thus, a vehicle showing this warning light is likely to need diagnostic testing to resolve any potential issues before it can pass inspection.
