What are the requirements for vehicle emissions testing?

In Connecticut, vehicle emissions testing is an important aspect of ensuring that vehicles meet environmental standards. The Department of Motor Vehicles (DMV/RMV) has established several requirements regarding emissions testing that vehicle owners should be aware of. First, all vehicles registered in certain areas of Connecticut are required to undergo emissions testing every two years. This applies primarily to vehicles that are model year 1981 or newer. There are exceptions to this requirement. For instance, vehicles that are less than four years old, as well as certain types of vehicles such as motorcycles, trucks over 18,000 pounds GVWR, and commercial vehicles that are not operated in emissions-sensitive areas, may be exempt from testing. Additionally, vehicles that do not operate in Connecticut or those that are considered historical vehicles may also be exempt. The emissions test measures the concentration of various pollutants from the vehicle's exhaust system. If a vehicle fails the emissions test, the owner will need to make the necessary repairs to meet the required standards. After completing repairs, the vehicle can be retested. It is important for vehicle owners to keep in mind that they must present their vehicle for testing at an authorized emissions testing center.
