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.
To mitigate the increased fuel consumption and mechanical wear associated with higher weights, companies are increasingly enrolling their staff in an efficient driving and fuel-saving course, which provides the necessary skills to handle 44T combinations sustainably.
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.
