To manage the Connecticut Emissions Program, the State of Connecticut has combined the resources of the Department of Motor Vehicles (DMV) and Opus Inspection. The DMV provides oversight of the emissions program, while Opus Inspection manages testing, equipment, service, inspector training, and motorist relations.
Connecticut tests nearly 1.3 million vehicles per year. Vehicles are tested every two years by a network of more than 200 privately owned automotive service facilities located at convenient locations throughout the state. By identifying polluting vehicles in need of repair, the state continues to improve air quality and meet regulations imposed by the Environmental Protection Agency (EPA) and the Clean Air Act.
