What must you consider when coupling a trailer with ball coupling?

When coupling a trailer with ball coupling, it's crucial to ensure both safety and functionality. The claw of the coupling must close securely to prevent any disconnection while driving. This is a fundamental requirement to ensure that the trailer stays attached to the vehicle, as per German traffic regulations.

Additionally, any support wheel must be lifted and secured before driving off. If the support wheel is not lifted, it can cause instability and may lead to accidents during transit.

The option stating that the support wheel must not touch the ground during coupling is often a misconception. While it is true that the support wheel should ideally be raised during towing, it is not a prerequisite for coupling the trailer itself. Understanding the correct sequence and requirements for trailer coupling is essential for safe and legal operation on the roads. Always ensure that all necessary steps are followed to comply with traffic regulations and ensure safety for all road users.
