Here is Our AI Assistant's Explanation
To check the state of wear of the drawbar or the turntable of a full trailer, it is essential to use a safe method that ensures the trailer remains secured while allowing for a test of the connection's stability. The correct approach involves briefly starting up the towing vehicle while the trailer is secured using the parking brake. This method allows you to check for any excessive play or movement between the towing vehicle and the trailer without the risk of the trailer rolling or becoming detached.
The driving technique mentioned in the other options—such as hard braking after deactivating the advance—could cause instability or even accident risk. Therefore, the combination of starting the towing vehicle with the parking brake engaged is necessary to ensure safety while accurately assessing the connection's condition, in accordance with German traffic regulations focusing on vehicle safety checks.
