Well after being blasted over at Fodor's for daring to state that an IDL is required for driving in Italy, I did a bit of research and found the following:
From the FAQ: I am an American citizen. To drive an auto in Italy, may I use my NY State license or do I need an International License? It is necessary to have an international license or your American state license accompanied by an official translation in Italian. Because this same rule is valid for the entire EU, we suggest applying for an international license so that you can drive throughout Europe and avoid having to carry multiple translations of your American license.
From the ACI site (department of motor vehicles in Italy):
Christina, I appreciate your time and effort as well. I think that guide book authors are a bit to blame for this confusion because even though most recommend the IDP, sometimes they imply that it is not mandatory. For example, I will quote the online version of Frommer's in this regard: "Technically, you need this permit, your actual driver's license, and an Italian translation of the latter (also available from AAA and CAA) to drive in Italy, though in practice the license itself often suffices. (Take all three along to be safe.)" So you see the confusion here, especially if the traveler consults only one source, doesn't have to show an IDP to rent a car and is never stopped in Italy for a license check or driving infraction.
I was on Fodor's yesterday doing research for my upcoming trip and I thought it was a hoot when you posted you hoped everyone without an IDP ended up in an Italian jail (I am paraphrasing).

It seems a little ridiculous doesn't it? Hundreds if not thousands of dollars for airfaire alone, housing, food, etc. and travelers balk at spending $10.00 for an IDL. Fortunately we have never been stopped, but we always get the licenses "just in case."
Christine, Howard posts on all 4 of the Italy travel boards under the name Italtrav. He doesn't post very frequently, but when he does it is always very accurate and authoritative information. I can't remember that he ever starts threads, and he usually only responds to threads about restaurants, hotels, and driving routes. On AOL boards we have people who post all manner of advice and opinion that isn't necessarily accurate. IDPs seem to be a favorite for misinformation. And it appears to be one of Howard's hot buttons. Not long ago, Pauline and I were talking about how we wished Howard would find his way to SlowTrav Talk. He would be a great contributor and I'm betting he would really enjoy the folks in this group.
