  1. I sweden its pretty much universal. The truck have about 3 meter from the fixed axel to the hitch. Of it have a tag axel its typically behind and counter stearing. If there is two tag axel the other one is always in front. Always keeping the same aproximate distance from the fixed axel to the hitch.

  2. The reason why you don't se than that often in the us is that a tractor truck is not counted to the length of the while, while a normal combined truck is. This law came around in 1984 same year as that movie perimiered pretty much exterminating that kind of combination over night

  3. ​ @BasedinReality1984 i would rather say that B double is the easier double hinge trailer to back up. While its less responsive than a A trailer its far easier to track. You can se what way its turning with the full size of the first trailer. While of cause you can se the front of the A trailer, it jack knifes in a second.

  4. It's not that hard, but there is quite a few things to check so the speed is never going to be anything other than a crawl. Also from friday sweden alow 32 meter trucks as well as electronic assisted stearing. So there can be a axel on the trailer that support going in reverse.
