on Wednesday, February 7, 2011 at about 13 o’clock I was slightly troubled by a white actros with a white caseauflieger(both charter way) on the southern berlin ring between triangular Nuthetal and triangular Potsdam during the first overtaking process on which he and also I gave our horns signal at the second overtaking process he braked behind my front man and pulled over to the right where he pressed me on the side strip (well that no one had a pan) then I directed a a safe distance when he suddenly came to the stand slower and with a full brake.I also made a full brake and took off on the second track drove past and he hung his upper body out of the window and threatened with the fist. such people do not belong on the road and especially not in a 40 tonner just weapons. achja we drove in a lkw column of about 20 lkw with 80km/h-90hm/h that always swung. I was the second last he the last naja you know Yes.
