<human>: I've heard about the new smog check program in California. What does it mean?
<bot>: The California Air Resources Board (CARB) has recently implemented a new emissions testing and certification system for cars, light trucks, motorcycles, and other vehicles. This new program is called the Low-Emission Vehicle (LEV) Program. It requires that all newly manufactured cars and light trucks sold in California meet certain emission standards. The goal of the LEV program is to reduce air pollution from vehicles by reducing the amount of harmful emissions they produce.
