The measure, which has now entered into force, responds to a long-standing demand from AECOC, one of the leading associations of transport-user companies across multiple sectors, representing nearly 35,000 businesses. AECOC first proposed the adoption of 25.25-meter Euro Modular Combinations (EMS) and the extension to 44 tonnes in 2001 to enhance freight efficiency and sustainability, while boosting industry competitiveness.
The Ministry of Transport’s backing and ongoing collaboration with AECOC were instrumental in pushing through this long-awaited reform. According to AECOC and the Department of Infrastructure of Transport and Territory at the Polytechnic University of Catalonia, implementing 44-tonne vehicles could reduce CO₂ emissions by up to 129,340 tonnes per year and eliminate over 2 million freight operations annually.

In addition to allowing higher vehicle weights, the new regulation simplifies the use of Euro Modular Combinations, raises the maximum allowed height to 4.5 meters in specific cases, and broadens the routes accessible to 44-tonne trucks. These changes are expected to not only improve operational efficiency but also help address pressing challenges such as driver shortages and the decarbonization of freight transport.
AECOC welcomed the final approval, calling it a key step toward reinforcing business competitiveness, reducing environmental impact, and meeting the evolving needs of the European road freight sector.
