When we were driving to Bremen, I took a few videos of us driving along the Autobahn. Here is one of them. In Germany all trucks are required to drive at a max speed of 80KM/hour, and they are not meant to pass each other between 6am and 11pm at night. Here is proof that most of them follow the rules! (This is also the first time I have tried to use YouTube Video. Lets hope it works!)
