What is a smog check?

A Smog Check is a vehicle inspection program designed to measure a car's emissions and ensure they meet state environmental standards. The primary goal is to reduce air pollution by identifying vehicles that emit excessive pollutants. Smog Checks are required periodically in many areas, especially for older vehicles or when transferring ownership. The test typically involves checking the exhaust, fuel system, and other components related to emissions. Passing a Smog Check is often necessary to renew your vehicle registration.
