Members of the American automobile association can go to their local club and have
the insurance coverage arranged for them should they plan to go to Europe, if they need to drive in any European city the coverage will be provided by a London firm if they were able to make the request before leaving home. Assistance can also be provided y a European car rental agency if you need protection. Consider that you are in Europe and not a race track when you are driving, to keep the momentum going and enjoy every bit of the experience, just be as responsible of a driver as you can be when in foreign soil.
