Question 482 in the bank

What is the meaning of the following traffic sign?

A white rectangular plate with a black border, showing a thick black arrow rising upward and bending to the right. Meaning: The notice above or below the road sign is only intended for vehicles turning in the direction of the arrow.
  1. Correct answer: The notice above or below the road sign is only intended for vehicles turning in the direction of the arrow.
  2. Right turn is permitted for restricted vehicles only.
  3. Right turn is to a one-way street.
  4. No right turn.

Why this is the answer

The correct answer in the official bank: The notice above or below the road sign is only intended for vehicles turning in the direction of the arrow.

This is a supplementary plate placed above or below another sign to limit its scope. The arrow bending right shows that the instruction on the accompanying sign applies only to drivers turning in the arrow's direction. Drivers going straight or turning elsewhere are not bound by it. The plate itself neither forbids the turn nor indicates a one-way street.
