Question 547 in the bank

When the following traffic sign is placed at the intersection:

A round blue sign with a white border, showing a single white vertical arrow pointing upward. Meaning: You are only permitted to drive straight ahead.
  1. You are only permitted to drive straight ahead from the left lane only.
  2. The road after the intersection is a one-way road.
  3. Correct answer: You are only permitted to drive straight ahead.
  4. Steep ascent ahead.

Why this is the answer

The correct answer in the official bank: You are only permitted to drive straight ahead.

A round blue sign with a straight white arrow is a mandatory sign. It tells drivers at the intersection to drive straight ahead only, and they may not turn right or left from there. It does not show that the road beyond the intersection is a one-way road, and it does not warn of a steep ascent, because other signs exist for those.
