Understanding Smog Check (CARB Test) for Diesel Trucks in Selma CA

A smog check, often referred to as a CARB test, is a mandatory emissions inspection for diesel vehicles operating in California. It measures pollutants like nitrogen oxides (NOx), particulate matter, and hydrocarbons emitted by heavy-duty trucks.

The California Air Resources Board (CARB) sets and enforces these standards to reduce air pollution and greenhouse gas emissions. Non-compliance can result in fines, penalties, or even suspension of operating permits. For fleet operators in Selma CA, failure to comply means trucks off the road—leading to downtime and financial losses.
