Massachusetts is not a member of the Drivers License Compact (Rhode Island is) but does have agreements with other states to share violation convictions. This means MA finds out about their drivers that commit traffic offenses out of state and reports to other states convictions of their licensed drivers' traffic violations.

The Massachusetts Registry of Motor Vehicles (RMV) driver handbook states that certain traffic offenses committed by a MA driver in other states will be placed on their driving record and treated as if the violation has occurred in MA.

The RMV notes as well that out of state violation convictions may count toward surchargeable events and thus possible license suspensions and Safe Driver Insurance Plan (SDIP) surcharges. Surcharge-able events are considered motor vehicle violations and at-fault accidents.

The Junior Operator's License fact sheet states that surcharge-able incidents under MA law, or the law of another state, can affect your JOL license. In accordance with the law, the RMV will suspend a JOL for 180 days if the holder is convicted of a second speeding offense or drag racing citations. It is a 1 year suspension for a third violation you were cited for before your 18th birthday.

From this information it would appear that the RI out of state speeding ticket would be seen by the MA RMV as a second speeding violation and thus cause the suspension of your Junior License. To make certain that this is the case though I would suggest contacting the MA Registry of Motor Vehicles.
