I have a US drivers license and will acquire a IDP soon. We are planning a trip to Germany, which will be part-sightseeing and part-road trip across the country. My question is, can someone possibly do the following? - rent a car in Berlin, drive south to Munich, go up north-east through Frankfurt and finally crossing the border into Netherlands, where we will return the car in Amsterdam and board the flight home. We are not sure whether we will pick Netherlands or Switzerland at this point. If its the latter, we will continue to drive south from Munich and cross the border and end the trip in Zurich.
Can someone do this with their US drivers license and IDP? Are any more documents required while renting the car? Do rental agencies in Germany allow to cross the border and return the car in a different country?
