The State of Lower Saxony in Germany has started a pilot scheme to allow 60 tonne trucks comprising a semi-trailer unit plus an additional trailer, making a total length of 25m, on certain roads. If the results of the trial are positive it's only a matter of time before they are allowed throughout Germany and after that they'll find their way over the whole of Europe. The mind boggles and I reckon it'll give quite a number of caravanners a scare when overtaking or being overtaken by one of those juggernauts.
