If you’ve moved to Connecticut from another state here is the process to trade in your out-of-state license for a Connecticut license:
Contact the Connecticut DMV or the Stamford Satellite Office of the DMV (Stamford Government Center, 888 Washington Blvd., 6th Floor, www.connecticutdmv.org).
After moving to Connecticut, you have 30 days to drive legally with your out-of-state license. After 30 days, the old license is no longer acceptable. If your old license expired more than 30 days earlier, you are obliged to go through the entire application and testing process to obtain a Connecticut license.
