In finland, there's one way to legally use those american style trucks for pulling semitrailers.
About 10 years ago, I saw a sleeper cab Scania T-model pulling a normal 13,6 meter semitrailer and got interested because it was clearly over the 16,5m length limit for the combination. The way he had made it legal, was that he had attached a second very short trailer behind the first trailer, and at that point the length limit for the truck and trailers changed to 25,25 meters with no limits on how long the truck itself can be, as long as the combination fulfils the turning requirements
