How are catalytic converters evaluated during Maryland inspections?

During Maryland inspections, catalytic converters are evaluated based on their presence, condition, and functionality regarding emissions control. The correct answer emphasizes that these components must be present and not tampered with, meaning they should be in their original configuration and operating as intended. This is crucial because the primary role of the catalytic converter is to reduce harmful emissions from the vehicle, ensuring compliance with environmental standards.

Additionally, emissions must fall within specified limits to pass the inspection. This ensures that vehicles on the road contribute to air quality standards and public health. This multifaceted evaluation aligns with regulatory requirements, distinguishing it from merely conducting a visual check or focusing solely on performance enhancement, which are not sufficient criteria for vehicle inspections.
