You want to drive an agricultural tractor with two trailers equipped with compressed-air brakes. What do you have to ensure you do with the manual brake power regulator on each of the trailers?

When driving an agricultural tractor with two trailers equipped with compressed-air brakes, it is essential to adjust the manual brake power regulator on each trailer according to the load carried. This is necessary because different loads can affect braking efficiency. If the regulator is not set correctly, the braking system might not function effectively, which can lead to difficulties in stopping and potentially cause accidents.

According to German traffic regulations, particularly those concerning road safety and vehicle operation, ensuring that the braking system is calibrated to match the load is critical for safe operation. Additionally, taking into account the actual gross weight of the tractor is important for understanding the overall dynamics of the vehicle-trailer combination when braking.

In summary, both adjusting the regulator based on the trailer load and considering the tractor's gross weight are crucial for the safety and functionality of the braking system when operating heavy machinery on public roads.
