What is the maximum permissible towed load behind a truck with a permissible total mass of 15 t (continuous brake system)?

In Germany, when a truck has a continuous brake system and a permissible total mass of 15 tonnes, it is allowed to tow a trailer with a maximum permissible load of up to 22.5 tonnes. This is because the continuous brake system ensures safe braking for the entire combination of truck and trailer. Without such a braking system, lower limits apply to prevent unsafe conditions. So, the maximum permissible towed load depends on the truck's braking system and total weight, ensuring safety on the road.
