In theory this is supposed to be possible. Check with the Italian consulate. Unfortunately there are a lot of fake violation fines filtering through from Italy, usually dating back a year or more. The threat is that you can be pursued for payment via UK courts even though you
have no idea whether you committed the alleged offence or not, and cannot defend yourself against it. Yet another bit of EU law that wasn't thought through properly. Or perhaps was, to the benefit of crooks and authorities and the detriment of EC citizens in general.
