Even though Massachusetts is not part of the Drivers License Compact (DLC) they do have agreements with other states to share information concerning moving violations with other states. Due to this fact they the Massachusetts courts are likely to inform the Pennsylvania DMV, or PennDOT, of your speeding ticket once your are convicted of it.
In Pennsylvania it is usually 4 points for a speeding offense of between 16 to 25 mph over the posted limit. However PennDOT has decided that minor out of state offenses, such as speeding, will not appear on your PA driving record. PennDOT also does not assess points for out of state minor traffic violations.
Insurance companies do not typically rate you according to the points on your driving record but the actual type of moving violations that you have on your driver's history. Since Pennsylvania does not place minor out of state violation convictions on your PA driving record it is unlikely, but not impossible, that your insurance rates would be affected by this MA speeding citation.
