When might a vehicle require a "Star Certified" inspection?

A vehicle may require a "Star Certified" inspection if it has a history of failing tests or is a high-polluting model. This designation is particularly important for vehicles that have demonstrated ongoing emissions issues or are classified as high emitters based on their design or performance. The "Star Certified" program is designed to provide a more comprehensive inspection process than regular inspection stations, focusing on ensuring that vehicles meet stricter emissions standards.

When a vehicle has previously failed smog inspections, it may indicate underlying issues that could contribute to higher emissions, and as such, it requires a more thorough evaluation to address these concerns. Likewise, high-polluting models are subject to additional scrutiny due to their potential impact on air quality.

In contrast, new vehicles typically do not need this level of inspection as they are designed to meet current emissions standards and are less likely to have serious issues. The other options, such as performance metrics or a mere request for premium service from the owner, do not align with the specific need for a "Star Certified" inspection, which is primarily tied to a vehicle's history with emissions compliance.
