sch.6-sec.1 Meaning of rear overhang and rear overhang line
This section defines rear overhang and rear overhang line for this Regulation. The rear overhang of a vehicle is the distance between the rear of the vehicle and the rear overhang line of the vehicle. For a vehicle with an axle group at the rear comprising only 1 axle, the rear overhang line is a line running along the centre-line of the axle. For a vehicle with an axle group at the rear comprising 2 axles, 1 of which is fitted with twice the number of tyres as the other, the rear overhang line is a line running parallel to the axles that is— closer to the axle carrying the greater number of tyres than it is to the other axle; and located at one-third of the distance between the 2 axles. For a vehicle with an axle group at the rear that is not an axle group mentioned in subsection (3) or (4) , the rear overhang line is a line running parallel to the axles down the centre of the axle group. For the purposes of applying subsection (3) , (4) or (5) to a vehicle, if an axle group includes at least 1 steerable axle, that axle is to be disregarded unless— the group comprises only 1 axle and that axle is a steerable axle; or all the axles in the group are steerable axles.
