"An emissions-controlled vehicle is any vehicle equipped with a factory-installed emissions control system designed to reduce air pollution. These systems include catalytic converters, oxygen sensors, EGR (Exhaust Gas Recirculation) valves, and diesel particulate filters (DPF). Most vehicles manufactured after 1975 are considered emissions-controlled and must comply with federal and state emissions laws when used on public roads."
