Manufacturers plates are usually located inside the vehicle cab and on the nearside.
On the manufacturers plate is provision to show vehicle DESIGN WEIGHTS also WEIGHTS NOT TO BE
EXCEEDED IN GT. BRITAIN (GB WEIGHTS) otherwise known as Maximum Authorised Mass (MAM). In cases where
there is not a DGW shown on a plate then the GROSS GB WEIGHT or MAM is used for brake percentage efficiency
calculations. Some vehicles first used before 1968 may not be fitted with a plate displaying gross weight. The brake
percentage efficiency of such vehicles must be determined by Decelerometer Test - see sub-section 3.7 B1.
Note: If the presented vehicle is fitted with a Ministry plate then the information displayed on that plate will always
override the information displayed on the Manufacturers plate. The registration number and chassis number on
the Ministry plate must always be cross checked to ensure the plate relates to that vehicle.
