Nothing to be apologize for; I'm sure that like Fountain Pen Network and the PIPORG-L list server, this board has people all over the world, who might be just as puzzled by such Americanisms for this type of truck/lorry as "tractor-trailer rig," "big rig," "semi," or the ever-popular "18-wheeler" (a 6-axle tractor with a 4-axle semitrailer, with dual wheels on all but the frontmost axle).
