What is the maximum vertical play permitted for a coupling pin?

The maximum vertical play permitted for a coupling pin is governed by safety regulations to ensure the secure connection between vehicles during transport. In the context of German traffic rules, this vertical play is essential to maintain stability and prevent detachment while driving. If the play exceeds the stipulated limit, it can lead to risks such as loss of control or increased wear on coupling devices.

By choosing the correct combination of options, you are identifying the specific measurement of vertical play that aligns with these regulations, ensuring vehicles are safely coupled and reducing the potential for accidents on the road. Understanding these regulations is crucial for maintaining the safety and integrity of vehicle operations.
