California’s Air Resources Board (ARB) requires refrigerated trailers operating in the state to be registered and assigned an ARB identification number to verify compliance with emissions regulations. For carriers running reefer units in California, having these ARB numbers is mandatory. Fleets based outside the state only need them if their equipment operates within California.

Our team can guide you through the ARB requirements and ensure your refrigerated trailers meet all necessary compliance standards.
