Program overview

Although you can’t see it, ozone pollution is a reality in Connecticut and across the U.S. Since cars and light-duty trucks contribute to the problem, their emissions control systems must be checked over time to ensure they are working properly to control the pollutants they emit. Connecticut's Emissions program, dating back to 1983, has a long history of effectively minimizing vehicle emissions and results in more emission reductions than any other state implemented air pollution control strategy.  Emissions testing helps identify pollution control devices that are malfunctioning and when fuel is being wasted. Detecting and repairing these problems can save on future repairs and reduces air pollution.
