Italian Driver License I Have An Italian Drivers License Is It Valid In The States?

I have an italian drivers license is it valid in the states? - italian driver license

Well, I'm 17, I'm half Italian and half american.The old, a car is driving in Italy to 18 years. Oldie 16th May take all motorcycles of 125 cc. You need a license to drive a motorcycle and in Italy the same license, you need a car with the only difference is drive that you do car.But practical test, if that is 18 ", 125 CC license is automatically license (after test (written test not necessary)) Since I will these states, I wondered if my license is valid for xmas for driving a car? If my license away? or at least a driver's license with my father?
The best answer Thanks.10points
