What total mass must a truck with trailer (two-axle truck, three-axle trailer, not combined traffic) not exceed?

For a truck with a trailer, where the truck has two axles and the trailer has three axles, the maximum allowed total mass is 40 tons. This is set by German regulations for vehicles operating outside of combined (intermodal) freight traffic. Knowing this limit helps ensure road safety and protect infrastructure. The answer you selected is correct; remember that 40 tons is the legal maximum in this situation. For similar questions, always pay close attention to the number of axles and whether combined traffic applies, as these factors directly influence the allowed total weight.
