How can you check mathematically whether the combination of an articulated vehicle (fifth wheel load = trailer load) exceeds the maximum permissible total mass of the train ?
Permissible total weight of the tractor plus permissible total weight of the semitrailer minus the trailer load
Permissible total weight of the tractor plus the permissible total weight of the semitrailer
Permissible total mass of the tractor plus the payload of the semitrailer
