How can you check the state of wear of the drawbar or the turntable of a full trailer?

The combination of options is important because it ensures a thorough inspection of the trailer's connection to the towing vehicle. Starting up briefly with the towing vehicle while the trailer is secured with the parking brake allows you to check for any unusual movements or noises in the drawbar or turntable, indicating wear or issues that may require attention.

This method is safer and compliant with German traffic regulations, as it prevents unintended movement of the trailer during the inspection process. In contrast, relying solely on other methods, such as braking hard while driving, may not effectively reveal the condition of the drawbar or turntable, and could pose safety risks.

In summary, the selected combination allows for a safe assessment of the trailer's stability and safety, which is crucial for ensuring compliance with vehicle regulations and maintaining road safety.
