You are driving an agricultural tractor with a mounted implement. After finishing working in the field, you want to drive on to a public road. What must you check first?

Before entering a public road with an agricultural tractor and mounted implement, you must check three key things: First, make sure the coupling device is secure and properly attached, so the implement cannot detach while driving. Second, ensure the implement is in its safe transport position for road use, which prevents it from sticking out or causing danger. Third, check that all lighting systems on both the tractor and the implement work correctly, as these are required for visibility and safety in public traffic. Following these steps is mandatory to ensure your own and others' safety and to comply with road regulations in Germany.
