On last week's episode of Eddie Stobart Trucks and Trailers, they showed
driver Mark working with a new illegal-length trailer that they have been
given special dispensation to trial on UK roads, by the DoT. They said
that it was called an "Eco-trailer" because being some 2 metres longer than
a 'standard' trailer, it would be able to carry nine more cages of Tesco
goods, which would mean less lorries on the road leading to a fuel and
pollution saving.

I am now working as a volunteer builder with Habitat for Humanity and do a
lot of motorway driving. Here there are an incredible number of what are
called B-Doubles: a tractor + trailer + trailer - 34 wheels so, I would
guess, moderate axle loads. They are restricted to certain routes but would
work in the UK for depot-depot operations.
