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?

To safely drive an agricultural tractor with a mounted implement onto a public road, it is essential to check several aspects to ensure compliance with German traffic regulations.

1. Checking the coupling device is crucial to confirm that the tractor and implement are securely connected. A loose or faulty coupling can lead to accidents or loss of control.

2. Assessing the transport position of the mounted implement is necessary to ensure it is in the correct position for road use. This positioning prevents hazards related to increased width or height that could obstruct traffic or cause accidents.

3. Finally, ensuring the proper functioning of the lighting systems is vital for visibility and signaling intentions to other road users, especially in low light conditions or adverse weather. German traffic law mandates that all vehicles on public roads must have operational lights.

By evaluating all these aspects before moving onto a public road, you help maintain road safety and comply with regulations designed to protect all road users.
