Check weight and axle loads before departure

Gross weight, axle limits and load distribution

You can easily stay below the permitted gross weight and still overload an axle if the load is placed incorrectly. Here you check both the gross weight and the individual axle loads before you drive — and correct the load distribution if it is uneven.

  1. Read the registration certificate

    Record the vehicle's own permitted gross weight and axle load from the registration certificate. These must never be exceeded — regardless of what the order's general limits allow for the vehicle type.

    The limits in the registration certificate always take precedence over the general table values.

  2. Find the applicable legal limits

    Look up the axle limits in BEK 1447/2025: single axle max. 10,000 kg, drive axle (twin wheels + road-friendly suspension) max. 11,500 kg. The gross weight depends on the number of axles — e.g. 2-axle lorry 20,000 kg.

  3. Know the gross weight limit for your vehicle combination

    For the largest vehicle combinations (7+ axles, vehicle + registrable trailer), the actual gross weight is 56,000 kg in 2026 and will be raised to 58,000 kg from 1 January 2027. Use the current value so the payload is not overestimated.

  4. Weigh on a weighbridge where you can

    Drive the whole vehicle onto a weighbridge for the gross weight, and weigh each axle or axle group separately on an axle weighing system where possible. An actual weighing is always safer than a calculation.

  5. Calculate the axle load with the moment method

    If you cannot weigh, calculate the axle loads from the position of the load: front axle load = Σ(weight · distance to rear axle) / wheelbase, rear axle load = total weight − front axle load. Use the «Axle load & load distribution» calculator.

    Try moving the load's centre of gravity in the calculator — you will immediately see how the axle loads change.

  6. Distribute the load sensibly

    Aim for the load's centre of gravity to lie at around 40–50 % of the wheelbase from the front axle. If you put a heavy load right at the back, the front axle is unloaded — which impairs both steering and braking.

  7. Check the remaining payload

    Calculate payload = permitted gross weight − kerb weight, and residual capacity = payload − actual load. If the residual capacity is negative, the vehicle is overloaded. Use the «Payload & weight check» and «Max. gross weight» calculators.

  8. Document the weighing

    Record the date, place, driver and the weighed gross and axle weight, and keep the documentation. Overloading and incorrect load distribution are punishable offences and increase both braking and accident risk.
