16In this Schedule " articulated vehicle " means a vehicle with a trailer so attached to the drawing vehicle that part of the trailer is superimposed upon the drawing vehicle, and when the trailer is uniformly loaded not less than twenty per cent. of the weight of its load is borne by the drawing vehicle.

19A heavy motor car or motor car drawing a trailer and being used as a public service vehicle or as a goods vehicle shall be treated as not drawing a trailer if the trailer is used solely for the carriage of a container or containers for holding, or plant and materials for producing, for the purpose of the propulsion of the drawing vehicle, any fuel that is wholly gaseous at sixty degrees Fahrenheit under a pressure of thirty inches of mercury.
20(1)Paragraphs 1 to 4 of this Schedule do not apply to, and paragraphs 5 to 12 apply only to, track-laying vehicles and vehicles drawing track-laying trailers or trailers some of which are track-laying.
