Are the passengers' weight included in the car's maximum permitted load?

The passengers' weight (but not the driver's) is included in the car's maximum permitted load. This means that you are probably not allowed to transport a lot of load if you have several passengers in the car.

The maximum load is the car or trailer's maximum permitted load according to the registration certificates.

Weights

Car's kerb weight: The weight of the car with the driver when it is unloaded and fully equipped (with tools, spare wheel, fuel, engine oil and water).

Trailer's kerb weight: The weight of the trailer when it is unloaded.

Gross weight: The actual weight of the car or the trailer at a certain moment. This means the gross weight varies depending on load and equipment.

Maximum load: The car or trailer's maximum permitted load according to the registration certificates.

Total weight: Kerb weight + maximum load.
