What all counts towards the weight of a commercial vehicle?
Your registration certificate contains a few details that determine how much your van can weigh: the unladen weight (or 'mass in running order'), the payload capacity, and the maximum authorised mass (MAM).
The unladen weight is the weight of the van in its standard configuration, including 90% fuel and 75 kg for the driver. Everything you load on top of that falls under the payload capacity. If you add these two together, you get the total weight your van is legally allowed to have.
Most delivery vans fall into the 3500 kg total weight class. This means that everything combined – the van itself, the interior, driver, tools, and materials – must stay below that limit. If you exceed it, you are officially overloaded and can receive a fine.
As of 1 July 2025, there is an exception: if you drive a sustainable commercial vehicle (such as electric or alternative fuel), you may drive with a B driver's license up to a total weight of 4250 kg. This only applies within the Netherlands, without a trailer, and if the driver has held their driver's license for at least two years.
How do you calculate the payload capacity of your commercial vehicle?
You calculate the payload capacity by subtracting the unladen weight from the maximum authorised mass.
For example: suppose your van is allowed to weigh 3500 kg and has an unladen weight of 2100 kg. That leaves you with 1400 kg for everything you carry.
You must count everything: the interior, tools, materials, fuel, yourself, and any passengers. An interior usually weighs somewhere between one hundred and two hundred and fifty kilograms, depending on what you have installed. Add a full tank of fuel and a few cases of tools, and you'll reach the limit faster than you think.
The influence of interior fittings on payload capacity
The material of the interior significantly determines how much payload capacity you retain. Van Storage Systems chooses a smart combination of galvanized steel and aluminium. The steel box sections provide strength and safety, while aluminium plates keep the weight low.
This gives you an interior that can take a beating but isn't unnecessarily heavy. In practice, a fully steel interior only differs by about fifteen to twenty kilograms compared to aluminium. This difference is small, while steel offers more advantages: it is stronger, more durable, has a higher load capacity, and is also more favourably priced. This way, you utilise the payload capacity optimally, without sacrificing quality or safety.
Conversely, an overly heavy interior can cause you to lose hundreds of kilograms of payload capacity. You'll notice this not only at a weighbridge but also in terms of handling, wear and tear, and fuel consumption.
What happens if you are overloaded?
An overloaded van drives unstably, brakes worse, and wears out faster. And if the police stop you, you can expect a fine. The higher the overload, the greater the penalty.
Overloading can also have consequences for your insurance, especially if it turns out that the vehicle was structurally used while overloaded. Overloading is therefore not just a matter of money, but also a safety risk.
In addition, zero-emission zones are coming into effect in more and more cities. If you drive there without complying with the rules, you risk a fine of €120 for a delivery van. A well-equipped, light van also helps in that regard: less weight means fewer emissions, less wear and tear, and more range for electric vehicles.
How to keep your commercial vehicle within the correct weight
A few practical tips:
- Choose an interior that is strong and light, for example, steel with aluminium.
- Place heavy items as low as possible in the van for greater stability.
- Weigh your van occasionally at a weighbridge, especially after modifications.
- Only bring tools you genuinely need.
- Don't forget that fuel, the driver, and passengers also count.
With a clever layout, you save weight and work more safely and efficiently.
Van Storage Systems: light, strong, and smartly designed
A commercial vehicle interior must be practical, but not unnecessarily heavy. Van Storage Systems works with systems featuring steel profiles for strength and aluminium elements for weight saving. This ensures that the interiors remain strong, safe, and within the legal limits of the payload capacity. The result is a van that remains light, well-organised, and reliable.
Conclusion
The payload capacity of your commercial vehicle is more important than many people realise. By intelligently managing the weight of your interior, you prevent fines, wear and tear, and unsafe situations. With the smart material choices of Van Storage Systems, you utilise the maximum payload capacity of your van without compromising on quality or safety. Strong where it needs to be, light where it can be.
