Plate or plating certificate

The HGV plate is form VTG 6A and must be securely displayed in the cab where it is easy to see and read. The HGV plating certificate is form VTG 7A and is kept with the vehicle paperwork in the office or with the vehicle.

For a trailer, the VTG 6T plate is displayed on the chassis. The VTG 7T plating certificate is kept with the relevant paperwork. Do not use a tractor unit's figures as a substitute for the trailer plate.

Weight terms to keep separate

Maximum authorised massThe permitted weight of the vehicle or trailer including the maximum load. GOV.UK also calls this gross vehicle weight or permissible maximum weight.
Gross train weightThe maximum permitted combined weight of the tractor unit, trailer and load. It may also be called gross combination weight.
Axle weightThe relevant limit for an individual axle or axle group. A vehicle can be within its gross limit and still have an axle problem.
Actual weightThe weight of the vehicle or combination as operated. It is established from dependable loading information or weighing, not by reading the permitted limit alone.

Before driving

  1. Confirm that the registration, VIN or trailer identity corresponds with the equipment being used.
  2. Check the vehicle function and configuration.
  3. Identify the gross, train and axle figures that apply.
  4. Compare them with the load and actual combination.
  5. Raise any mismatch, unreadable entry or missing document with the transport office.

The plate may also show dimensions, tyre conditions and other vehicle information. The plating certificate carries the same information and also shows tyre size and ply rating or load index.

When information changes

Certain notifiable alterations, including specified changes to the chassis, tyres, brakes or permitted weight, require the plate and plating certificate to be updated through DVSA. Drivers should not hand-correct a plate or assume that an old copy remains valid after a change.

Missing or damaged documents

Report the issue before use. GOV.UK provides a service to download a replacement HGV or trailer plating certificate and ministry plate. Follow the GOV.UK instructions for printing the replacement and displaying it in the specified location on the vehicle or trailer.
