Why this is the answer
The correct answer in the official bank: Slow down and shift to low gear. Refrain from prolonged brake use.
This sign warns of a steep descent, where the vehicle gains speed on its own. Slow down beforehand and shift to a low gear so the engine helps hold the vehicle back. Relying only on the brakes for a long time makes them overheat and lose effectiveness. Speeding up or using a high gear downhill is dangerous and reduces control.
