What must you bear in mind when loading a single-axle trailer?

When loading a single-axle trailer, it is crucial to consider three important factors: axle load, load on the coupling, and total mass.

1. Axle load refers to the weight that is placed on the trailer's axle. Exceeding the maximum axle load can lead to issues with handling and increase the risk of tire failure.

2. Load on the coupling is the weight that is transferred from the trailer to the towing vehicle through the coupling system. This load affects the handling and stability of both the trailer and the vehicle.

3. Total mass is the combined weight of the trailer and its load. It's essential to ensure that this total mass does not exceed the legal limits prescribed for the trailer, as exceeding these limits can lead to unsafe driving conditions and legal penalties.

Proper distribution and consideration of these factors help ensure safe and efficient driving while also complying with German traffic regulations. Each item is interconnected and important for maintaining stability and legality on the road.
