Weights and dimensions: what may my truck weigh and measure?

Short answer: How heavy and how large your truck may be is set out in Directive 96/53/EC. For standard international traffic the maximum total weight is usually 40 tonnes, and 44 tonnes for intermodal transport (containers to or from rail or water). The Commission wants to revise these rules, but that proposal is not yet in force: the current limits still apply.

What do the rules say now?

Directive 96/53/EC sets the maximum weights and dimensions for heavy commercial vehicles operating in national and international traffic. The directive ensures a level playing field between Member States and protects roads and bridges. In broad terms:

• Maximum weight: in international traffic typically 40 tonnes total weight; for intermodal container transport this rises to 44 tonnes.
• Axle weights: separate limits apply per axle and per axle group, so the load on the road surface stays manageable.
• Dimensions: standard maximum lengths (for example 16.5 m for a tractor-semitrailer and 18.75 m for a truck with trailer), a width of 2.55 m (2.60 m for refrigerated trailers) and a height of 4 m.

Member States may deviate for domestic traffic or allow heavier/longer combinations (such as the "ecocombi" or EMS), but cross-border use of these is currently limited and not uniformly regulated.

What changes under the proposal?

In 2023 the European Commission proposed a revision (COM(2023) 445). Key points from the proposal (not yet in force):

• Extra weight and length for zero-emission powertrains and for aerodynamic features, so that clean trucks are not penalised by the heavier battery pack.
• Clearer rules for cross-border use of longer and heavier combinations (EMS) between Member States that allow this between themselves.

Until this proposal is adopted and transposed, the limits in 96/53/EC remain in force.

What does this mean for the switch to electric trucks?

An electric truck weighs more than a comparable diesel version because of its battery pack. Directive 96/53/EC already provides scope for a limited weight allowance for alternative powertrains, so your payload does not drop unnecessarily. Keep in mind that the axle weights remain decisive: the extra weight must fit within the axle limits. So when purchasing, check whether the chosen configuration reaches the desired payload under the current rules, and track whether the revision offers further scope.
