How Do I Find The Weight Of A Vehicle?

The Gross Plated Weight is the total permitted weight of a loaded vehicle. It is shown:

on motor vehicles - on the manufacturer's plate, which is attached to the vehicle after it is first registered
on trailers - on the manufacturer's plate.

The plate is usually found:

on motor vehicles - inside the cab in a conspicuous position.
on trailers - on the nearside, often on the headboard.

If you do not know the unladen weight you should take the unladen vehicle to a weighbridge. The Department of the Environment's Driver and Vehicle Testing Agency (DVTA) will be able to advise you of weighbridges near you.
