5 Determination of wheel, single axle, axle group and aggregate axle loads

(1)  An authorised officer may determine the wheel load, single axle load, axle group load or aggregate axle load of a heavy vehicle –

(a) by causing to be placed on a weighbridge –

(i) any wheel separately; or

(ii) all the wheels on any single axle; or

(iii) all the wheels on any axle group; or

(iv) all the wheels on the vehicle; or

(b) by causing to be placed on a portable weighing device or devices –

(i) any wheel separately; or

(ii) the outer wheels on any single axle; or

(iii) the outer wheels on each axle of any axle group; or

(iv) the outer wheels on each axle of the vehicle.

(2)  A load, or the sum of any loads, determined under subregulation (1) is the wheel load, single axle load, axle group load or aggregate axle load, as the case may be, of the vehicle to which it relates, whether or not any wheel of the vehicle in relation to any other wheel of the vehicle was, at the time of determination, in alignment of the same horizontal plane, unless the divergence from that alignment exceeds 150 millimetres.

(3)  The aggregate axle load of a vehicle may be determined by adding together the axle loads of all the axles.
