CARB certification
What is a CARB certificate?
A CARB certificate is the official Clean Truck Check compliance certificate you download from CTC-VIS after your heavy-duty vehicle is reported, the annual CARB compliance fee is paid, and a passing emissions test is on file. CarbTestFinder helps with CTC-VIS filing so you can download the certificate from the state portal.
“CARB certification” for trucks usually means this Clean Truck Check certificate process — not the factory “CARB certified” engine label. You get the certificate online from the CTC-VIS portal after registration, the annual compliance fee, and a passing test.
