U.S. emission testing programs

We operate centralized programs, where we provide a complete inspection and program management service in our own inspection stations; and decentralized systems, where we support independent stations with services such as testing equipment, Vehicle Inspection Database, training, PR and helpdesk support.

In several U.S. states we complement regular emission testing with remote sensing, including Clean Screen programs where motorists can choose to have their emissions tested at the roadside and earn an exemption from their next scheduled emission test if their vehicle passes clean.
