From KK in other thread....

I think "articulated lorry" describes a vehicle where the cab/tractor bit at the front bolts on to a container at the back, thus enabling the lorry to jackknife and spill its contents all over the road, as opposed to a vehicle where the cab is an integral part of the storage space. Do you follow me?
Well, if people HAVE to live in the things they drive, at least the dwellings are well-spoken.
