You are driving a tractor with an attachment. After working in a field, now you want to drive on a public road. What should you note first?

The combination of options you selected is necessary because each item ensures safety and compliance with German traffic regulations when operating a tractor with an attachment on public roads.

1. Locking the foot pedals for the single wheel brake is essential to prevent accidental activation while transporting the vehicle. This helps maintain control.

2. Ensuring that the attachment is in its transport position is crucial for safe maneuverability on the road. An improperly positioned attachment can create hazards for other road users.

3. Attaching the necessary warning panels to indicate the vehicle width is important for visibility and safety. These panels alert other drivers to the size of your vehicle, which may extend beyond normal lane boundaries, helping to prevent collisions.

All three components combined prepare the vehicle for safe travel and comply with traffic laws aimed at protecting both the driver and other road users.
