In an emissions inspection program, a minimum passing rate of 90% is required to be considered successful. This benchmark is established based on guidelines for ensuring that the program effectively contributes to reducing air pollution and promoting cleaner vehicles on the road. A passing rate of 90% indicates that the majority of vehicles are complying with emissions standards, which helps to improve air quality and public health.

Achieving this threshold demonstrates the program's ability to identify and address vehicles that do not meet emissions requirements, thereby confirming that the majority of the fleet is operating within acceptable limits. A lower threshold, such as 80% or 85%, would suggest a less effective program, potentially allowing a significant number of non-compliant vehicles to remain operational, thereby undermining the program's goals of environmental protection and compliance with regulatory standards.
