What happens to vehicles that fail emissions inspections multiple times?

When a vehicle fails emissions inspections multiple times, it may undergo additional scrutiny. This means that the vehicle will be closely examined to determine the reasons for its repeated failures, and it may require further inspection or repairs before it can be certified as compliant with emissions standards. The enhanced emissions program has stringent regulations to ensure that vehicles meet environmental standards, and repeated failures indicate a persistent issue that could affect air quality. Thus, additional scrutiny is crucial in addressing these problems and ensuring that the vehicle is properly maintained or repaired to minimize emissions.
