Abstract

A decentralized method and system for vehicle emissions testing preferably uses the OBD unit of the vehicle to be tested. A preferred implementation of the method and system includes a remote overview or supervisory location in communication with a plurality of decentralized inspection stations or test locations. Supervisory personnel at the remote overview location are in video and data communication with the inspection location and thus are able to monitor and audit all aspects of the OBD testing process, including a review of the actual test data.
