     Australian B-doubles generally have eight or nine axles, with increasing interest in Quad-axle B-doubles for some applications, including the carriage of two 40 foot containers through urban areas.

   • 2011, Sophia Rendell, Brisbane Valley Underbelly, page 87,

     I mean there were the little things like the B-double that was allowed in the town and actually allowed to park in the street until it was ready to leave on its next trip. Not only is this illegal but a B-double is not allowed to leave the designated route at any time.

The Australian freight road industry was able to persuade Governments to call them B-Doubles. This was to reduce potential confusion with road trains and also help overcome some public opposition that persisted, in some urban areas, to the mid-1990s.
