A 3.5 tonne van is a van with a maximum authorised mass (MAM) of 3,500kg. MAM, sometimes called gross vehicle weight, is the total the vehicle is legally allowed to weigh when fully loaded. It includes the van itself, the driver, fuel, and every item in the load.
The 3,500kg figure matters because it is the dividing line for UK driving licences. A standard category B (car) licence allows the holder to drive a vehicle up to 3,500kg MAM. Anything heavier is classed as a large goods vehicle and needs a category C1 or C licence, which is why most man-and-van and small-removals vehicles are built right up to, but not over, the 3.5 tonne limit.
An important distinction for anyone booking a move:
- MAM is the maximum legal loaded weight: 3,500kg.
- Kerb weight is what the empty van weighs on its own.
- Payload is the difference between the two, and it is what you can actually carry. On a typical 3.5 tonne Luton van, payload is usually somewhere between 800kg and 1,200kg.
Overloading a van past its MAM is both an offence and a safety risk. It lengthens braking distances, strains the tyres and suspension, and can invalidate insurance. A van that looks like it has space left can still be over its weight limit, which is why an experienced operator plans the load by weight as well as volume.
