If you are traveling internationally and plan on driving, be sure you get an international driving license first. Most countries don't require you to have one, but it's better safe than sorry. Also, since the international drivers license is printed in multiple languages, even if it's not required, it may happen to be readable by whomever is trying to read it, and that will certainly make things easier for you if you don't speak the language. You can get an international drivers license at any AAA office, and they are under $10, so it's a worth-while investment
