The phrase refers to a mandatory vehicle emissions inspection conducted within the city of San Jose, California. This inspection is a requirement for vehicle registration renewal and ownership transfer, ensuring vehicles operating within the area meet established air quality standards. Failure to pass results in the vehicle requiring repairs and subsequent re-inspection before registration can proceed.
These inspections are crucial for maintaining air quality and public health in the region. By identifying and rectifying vehicles with excessive emissions, the process helps reduce pollutants such as smog and harmful gases, contributing to cleaner air and mitigating respiratory problems. The practice reflects a broader historical trend towards environmental regulation and awareness of the impact of vehicle emissions on urban environments.
