Question 670 in the bank

What is the meaning of the following traffic sign?

Two black-bordered white squares side by side; the left shows a black arrow pointing diagonally down-left, the right a black arrow pointing diagonally down-right. Meaning: Merge with the traffic in the adjacent lane, from either right or left.
  1. Road works - drive in the direction of the appropriate arrow.
  2. Lane is closed. No driving in the lane under the traffic sign.
  3. Correct answer: Merge with the traffic in the adjacent lane, from either right or left.
  4. A hairpin turn, either left or right.

Why this is the answer

The correct answer in the official bank: Merge with the traffic in the adjacent lane, from either right or left.

A diagonal arrow pointing down tells you to move to the adjacent lane and merge with the traffic there, to the side the arrow points to: right or left. The sign does not announce that the lane is closed, and it does not indicate a hairpin turn or road works.
