What is a 'smog check'?

A 'smog check' refers specifically to the process of assessing a vehicle's emissions to determine whether it meets the state's environmental standards. This check is typically a preliminary inspection that evaluates the vehicle's emissions control system and overall performance to ascertain if more comprehensive emissions testing is necessary.

This process serves as a critical initial step in identifying vehicles that may need further examination or repairs due to potential emission failures. If a vehicle is found to potentially exceed emissions limits during the smog check, it will then be subjected to a full emissions control test to ensure compliance with legal standards.

Understanding the context of this terminology is essential as it relates to broader efforts to monitor and manage air quality. The smog check acts as a gateway to more extensive testing and necessary actions to keep vehicles compliant with emissions laws.
