How can a driver of an agricultural tractor with a trailer control the vehicle trajectory while reversing?

Reversing a vehicle combination requires constant and alternating observation of the road at various points. Looking through the rear window allows one to assess the angle of the trailer in relation to the towing vehicle, whereas the exterior mirrors are essential for controlling the trailer's path and maintaining a safe distance from the edge of the carriageway and obstacles. The use of both these methods simultaneously ensures full control over the vehicle and is crucial for the safe execution of the manoeuvre.
