Question 549 in the bank

What is the meaning of the following traffic sign?

A blue circle with a white border showing a white arrow that splits into two arrows, one pointing right and one left. Meaning: Turn right or left.
  1. Winding road in both directions at the next intersection.
  2. Correct answer: Turn right or left.
  3. No U-turn to the left.
  4. Pass the place that is marked with a signpost from its right only.

Why this is the answer

The correct answer in the official bank: Turn right or left.

A round blue sign is a mandatory sign, and its white arrows show the directions you are allowed to take. Here the arrow splits to the right and to the left, so you must turn one of those two ways and may not continue straight ahead. It is not a winding-road warning, which would be a red-bordered triangle, nor a U-turn prohibition.
