Question 545 in the bank

What is the meaning of the following traffic sign?

A blue circle with a white border, showing a white vertical arrow pointing upward in the centre. Meaning: Drive straight ahead only.
  1. Two-way traffic ahead.
  2. Entrance to a one-way street.
  3. Pass the place that is marked with a signpost from its right.
  4. Correct answer: Drive straight ahead only.

Why this is the answer

The correct answer in the official bank: Drive straight ahead only.

A round blue sign is a mandatory sign that tells you what you must do. A white arrow pointing upward means you must continue straight ahead only, with no turning right, left or making a U-turn. Don't confuse it with the one-way street entrance sign, which is rectangular, or with the diagonal arrow sign that tells you to pass on the right.
