paid traffic ticket in Italy

Was the ticket given to you by a camera? If so I believe it's possible to get multiple tickets if you drive through multiple times, even if it's only a couple minutes apart. I don'tk now if that's true in Rome for this kind of violation but it seems to be true for ZTL violations. It may be that you drove through more than once, or it could be a mistake with their camera/electronic system. If the latter, or if it wasn't given by camera, I would do what Frank says and i would also advise posting in the Rome Tripadvisor forum because it's very busy over there and there are several locals who post regularly who I think would be willing to assist you. Good luck!!

It could be multi ticket but assume it is not. Personally, my approach would be this. I would put all of the doc together with a cover letter explaining everything, payment, etc., and mail it to the appropriate office. I would keep a copy of everything and take it with me on my next trip to Italy should this somehow pop up on entry -- which is very unlikely. And then ignore anything else unless you received a very good explanation of why your response was inadequate. It can be hard to beat the Italian system.

This seems obvious, but do each of the notifications you received show the same ticket number? If so, and if you have proof of payment, I would follow Frank's advice. If you did have two violations, there should be two ticket numbers.

Lawrence, At the risk of appearing a scofflaw, why not just ignore it? What's the worst that can happen, will they extradite you back to Rome to pay the traffic ticket?
Look at the bright side, free Italy trip!

Pat, would you give the same advice to an Italian who had received a ticket in Monkland, MD ? Would you actually advise this fictional Italian to ignore U.S. law?

Norma, it is not right to ignore the law. But the Italian system is so difficult to get answers and find correct information. You would spend HOURS of time. And even it he would pay it again, does not mean the system would not recognize it a second time. The earlier enrty is correct. Attempt to send an appropriate response, make copies then forget about it.

Of course, you are right, David, but I was responding to Pat's post in which she (he?) suggested just ignoring the ticket because "what's the worst that can happen?"

Guys, I am not advising to ignore the ticket, just the incorrect, repeated billing of a ticket already paid. Having done the correct thing and paid the ticket, Lawrence is not required to make copies and mail them to compensate for an inefficient system in another country. On our first trip to Italy, we mistakenly went through a toll behind a truck, it took 4 years for them to send me a ticket. We paid, and now once a year like clockwork we get another bill.
My responsibilities ended when I sent in payment. Lawrence's should too.

Things happen so slowly in Italy that they probably have never gotten around to processing the paperwork. You are probably being sent computer generated notices. Send them proof of payment and leave it at that.

Lawrence; ignore it! No one is going to send the Caribinari over here to pick you up. If it was truely one ticket, you have done your part. You have your proof that you paid. Why worry. When my brother got a ticket like this, he ignored it. When he went back the next year the rental agency didin't say a thing, and the cops didn't wisk him away. Don't worry; be happy.
