Why this is the answer
The correct answer in the official bank: Slow down and keep to the right before entering the curve.
The warning sign alerts you to a curve to the right, so slow down early and keep to the right. This lets you stay in control of the vehicle and not drift into the opposing lane. The number 90 is a maximum speed, not a speed you must drive at. In any case, adjust your speed to the curve and the road conditions.
