Some of the new drivers licenses can be used at the border, they have the information needed for CBP on the stripe that can be read by the scaning unit, in Europe the majority of police know English and do know what a drivers license of a foreighn country looks like, it is in the USA that some LEOs have an attitude that unless it is an American document they do not accept any passport or drivers license from a foreign country, a friend of mine from Sweden got arrested in Nebraska for not having a valid drivers license, he was on a 2 week vacation in the USA in a rental vehicle, we had to contact the Swedish embasy so that a representative would go to him and straigten things out, four days latter he was out and left for Sweden asap, he never wants to visit again.
