While Massachusetts is not part of the Drivers License Compact (DLC), while Connecticut is, they are both part of the Non-Resident Violators Compact (NRVC).

The DLC requires member states to report tickets convictions back to the licensing state of the motorist who received the moving violation. The NRVC requires member states to suspend the driver’s license of those who get traffic tickets for moving violations in other states and fail to pay them.

Chapter 2 of the Massachusetts Driver's Manual states that if your license or driving privileges have been suspended or revoked in another state, your Massachusetts license will be suspended automatically.

If the RMV suspends or revokes your driver’s license, you must stop driving immediately. You have lost your driving privileges, and it is illegal for you to operate any motor vehicle.

The MA Registry of Motor Vehicles also states that if your Massachusetts license is revoked due to a suspension or revocation in another state, you must be reinstated in that state before you can resolve any revocation in Massachusetts.

Once you have resolved the suspension or revocation in the other state, you may resolve your revocation in Massachusetts by bringing either a reinstatement letter or a current driving record from the state of suspension to any full service RMV branch office.

So it would appear the Connecticut speeding ticket that was not paid and thus suspended your license in that state can affect your driving privileges in your home state of Massachusetts as well. You can contact the RMV to find out more information. If you find that your license has been suspended then you will need to resolve the ticket issue with CT so that you can then reinstate your MA license.
