In the US you can get an IDP from an automobile association, even if you’re not a member. If you want to drive in Austria, you should get an IDP. The IDP itself is a paper booklet with translations of what’s on your driver’s license in 10 languages, so people in multiple countries can understand what kind of license you have. More than 150 countries in the world subscribe to at least one of the UN treaties and allow you to drive there with your domestic driver’s license and an IDP. Since 1926, the United Nations has regulated driving in a foreign country through international agreements. If you don’t know why you need one, how to get one, and when and where to use it we answer those questions and more. Getting one is fairly straightforward, depending on what country you live in, and it will allow you to take your driving adventures around the world. When you plan a road trip in another country, one thing you should put on your to-do list before you go is getting an International Driving Permit (IDP).
