What happens if you live in Maryland and get a ticket in Virginia and you fail to pay the ticket do they put a warrant out for you?

I was told by a Pennsylvania State policeman (as he held my California drivers license and wrote my speeding ticket) that the states have agreements to enforce collection of each other tickets, so that if I didn't pay the PA ticket, CA would collect the money from me or, failing that, suspend my license and not renew it. I don't know if that is how it works, but that's what the man said.

I got a speeding ticket in Virginia in 2005. Still have not paid it. I live in NY. My license was never suspended or anything.
