What is the maximum play the towing fork may have in the bearing bushes in towing direction?

The correct answer, "No noticeable play," is important because it ensures safe towing practices. According to German traffic regulations, any noticeable play in the towing fork could lead to instability when towing, increasing the risk of accidents. Proper maintenance and adherence to these standards ensure that the connection between the towing vehicle and the trailer is secure, preventing potential hazards on the road. Therefore, it is critical for safe vehicle operation that no noticeable play is present in the bearing bushes in the towing direction.
