How Cargo Position Changes Axle Loads

Moving cargo 1 metre along the trailer shifts over 1,000 kg between axle groups. Learn the physics, the EU limits, and how to balance every load correctly.

EU Regulations

EU axle load limits for tractor-trailers

Standard limits under EC Directive 96/53. Individual member states may apply stricter national rules.

Max GVW (5-axle)

40,000 kg

44,000 kg for intermodal

Steer axle

7,500 kg

Single non-driven axle

Drive bogie

19,000 kg

Dual axle, ≥1.8 m spacing

Trailer bogie

21,000 kg

Dual axle, ≥1.3 m spacing

Kingpin (5th wheel) load

12,000 kg

The kingpin load is the vertical force on the 5th wheel plate. It is not measured directly by roadside axle scales — inspectors calculate it from steer and drive axle readings. Exceeding 12,000 kg stresses the tractor frame and triggers an automatic prohibition order in most EU countries.

Overload fines

€1,000 – €10,000

Fines are applied per overloaded axle group. Germany, the Netherlands, and Scandinavia apply the harshest penalties. The driver, haulier, and loading company can all be held liable simultaneously. Repeat violations result in licence suspension.

When to recalculate

Before every trip

EU regulations place responsibility for load distribution on both the driver and the loading party. A printed loading plan with calculated axle weights is your primary legal defence in a roadside inspection. Recalculate after any cargo change, including partial unloads on multi-drop routes.
