When driving a tractor with a loaded trailer, what should you do before entering a long section of the road going upwards?

Explanation
Correct answer: Engage such a gear that guarantees that it will get to the top without reducing gears.
When driving a heavy vehicle combination, such as an agricultural tractor with a loaded trailer, you should select a gear in advance that will provide sufficient power to climb the incline visible in the picture without needing to change down. Attempting to change gear on the incline could lead to a loss of motive power and speed, and consequently may even cause the vehicle to stop, which is a dangerous situation.
