What can be the consequences if the tow-bar of a towing coupling has longitudinal play?

The selected combination of answers is correct because both points highlight critical safety issues related to the longitudinal play of a tow-bar.

1. When cracks form in the cross member where the towing coupling is attached, it can compromise the structural integrity of the entire towing system. This can lead to failure during towing, creating hazards for other road users.

2. If the towing coupling tears off due to excessive play, it could result in the towed vehicle becoming detached while in motion. This poses a serious risk of accidents and collisions.

In German traffic law, ensuring that towing equipment is in good condition is vital for road safety. Regular inspections and maintenance are required to prevent such issues from arising, as they can contribute to dangerous situations not just for the driver but also for others on the road. Therefore, recognizing the consequences of towing coupling imperfections is essential for safe driving practice.
