What is the maximum permissible weight of a trailer behind a truck of 10 t permissible total mass with continuous brake system?

In German traffic law, when a truck has a permissible total mass (zulässiges Gesamtgewicht) of 10 tons and is equipped with a continuous brake system (durchgehende Bremsanlage) on the trailer, the maximum permissible weight of the trailer can be up to 1.5 times the permissible total mass of the truck. This means the trailer can weigh up to 15 tons. This rule is set to ensure that the braking system of the trailer can handle its weight safely, preventing accidents due to insufficient braking power. If the trailer does not have a continuous brake system, the maximum allowable trailer weight is less. So, because the truck is 10 tons and the trailer has a continuous brake system, the maximum trailer weight allowed is 15 tons.
