On 'Ministry' and manufacturer's plates there is provision to
show vehicle 'DESIGN WEIGHTS' also 'WEIGHTS NOT TO BE EXCEEDED

a 'DESIGN GROSS WEIGHT' shown on a plate then the 'GROSS GB
WEIGHT' is used for brake percentage efficiency calculations.

a 'ministry' plate or a manufacturer's plate displaying gross
weight. The brake percentage efficiency of such vehicles must
be determined by Decelerometer Test - (See Subsection 3.7) |
