Thanks everyone!
I just talked with the MA DMV, the person responsible for points, and they said the only way they would know about it is if VA posts the ticket on the National Driver Register.
National Driver Register (NDR) | National Highway Traffic Safety Administration (NHTSA)
So I have to find out if VA posts 71 in a 55 on the NDR. If they don't, I'll just pay the ticket.
If they do, I'll have to hire a lawyer and/or show up in court on August 21. Will make a vacation out of it, have been wanting to go to DC for a while now.
My guess is they do.
