The state of Connecticut Vehicle Emissions Testing program has certain testing hours and a testing schedule that you should be aware of prior to attempting to getting your car tested.  The vehicle emissions testing official hours are Monday – Friday from 8:00 a.m. until 5:00 p.m. and on Saturday from 8:00 a.m. until 1:00 p.m.   It is recommended that you call the testing center you plan on visiting ahead of driving there to ensure they are open.

The vehicle emissions testing program is closed on certain holidays each year.  These holidays are New Year’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.  You should plan your vehicle emissions testing date accordingly.
