Weight and Dimensions Regulations: 44 Tons
Updated Guide 2026: Technical requirements, axle configurations, and the legal impact of mass expansion in road freight transport.
Chapter 1: The transition to 44 tons in European logistics
The amendment to Annex IX of the General Vehicle Regulations has marked a turning point in logistics competitiveness. The move from 40 to 44 tons is not just a load increase; it is a total reconfiguration of transport operations. This measure aims to reduce emissions per ton transported and optimize fleets in an increasingly integrated European market.
However, this mass increase entails greater responsibility in the legal maintenance of the vehicle. A 44-ton combination exerts higher pressure on the braking system and tires, necessitating more rigorous monitoring of the safety data recorded by second-generation smart tachographs.
Chapter 2: Axle configurations and technical requirements
Not all trucks can immediately haul 44 tons. The 2026 regulations specify clear configurations to ensure road safety and infrastructure protection.
Requirements for 44-ton combinations:
- Motor Vehicles: Must have at least 3 axles.
- Semi-trailers: 3-axle configuration with pneumatic suspension or equivalent.
- Engine Power: Minimum power-to-weight ratios are required to prevent risks on steep gradients.
- Active Safety: Mandatory advanced braking systems and stability control (ESC).
Chapter 3: How weight increase affects tachograph control
Although the tachograph does not directly measure vehicle weight, the maximum load influences driving dynamics. A fully loaded 44-ton truck requires longer braking distances and more rigorous rest time management to prevent driver fatigue.
Furthermore, in the event of a motion sensor error during heavy-load transport, the suspicion of technical tampering increases during inspections. It is vital that the .DDD file is analyzed regularly to ensure there are no speed spikes or anomalies suggesting the vehicle is operating outside its legal capacities.
Chapter 4: Summary of Maximum Authorized Mass (MAM)
| VEHICLE TYPE / COMBINATION | AXLES | MAXIMUM MASS (MAM) |
|---|---|---|
| Rigid Truck | 2 Axles | 18 Tons |
| Rigid Truck | 3 Axles | 25/26 Tons |
| Road Train | 4 Axles | 36 Tons |
| Articulated (Standard 44) | 5 or more Axles | 44 Tons |
| Euro-Modular (Mega-Truck) | 6 or more Axles | 60 Tons |
Any excess over these masses carries penalties that can be consulted in our updated sanctions scale.
Chapter 5: The cost of exceeding 44 tons
Overweight is one of the most targeted offenses at roadside weighing stations. Responsibility does not always fall exclusively on the carrier; the loader also has a shared legal liability regarding the stowage and weighing of the vehicle.
Overweight fines are graduated according to the percentage of excess. A 5% excess may be considered minor, but exceeding 20% enters the territory of "Very Serious" infringements, which can exceed €4,000 and jeopardize the company's transport license.
Efficiency under legal control
The adoption of 44 tons is a golden opportunity to improve profitability, but it requires flawless technical and documentary control. At TachoTools, we help companies manage this transition by ensuring their tachograph data reflects impeccable operations. Do not let increased load become an increased legal risk; use our .DDD file analysis technology to shield your business.
