What is the maximum permissible total mass of an articulated motor vehicle (three-axle truck tractor, three-axle semitrailer) in combined traffic with 40 feet ISO containers?

The maximum permissible total mass for an articulated motor vehicle (a combination of a three-axle truck tractor and a three-axle semitrailer) carrying 40 feet ISO containers is 44 tons according to German traffic regulations. This higher weight limit is allowed because the vehicle configuration and load type meet specific criteria, such as axle distribution and container dimensions, which ensure road safety while maximizing transport efficiency. The 40-ton or 38-ton limits apply to other vehicle setups or loads but not to this particular combination. Understanding these limits helps ensure vehicles comply with legal weight restrictions, preventing damage to roads and enhancing traffic safety.
