Question 554 in the bank

You are driving a commercial vehicle and come across this traffic sign:

A white-bordered blue circle with two diagonal downward arrows: a yellow arrow pointing left and a white arrow pointing right. Meaning: Pass only from the right. Only public transportation is allowed to pass from the left as well.
  1. Correct answer: Pass only from the right. Only public transportation is allowed to pass from the left as well.
  2. Pass only from the left. Public transportation is allowed to pass from the left as well.
  3. Drive only straight (forward).
  4. Pass from the right or from the left; whatever is comfortable for you.

Why this is the answer

The correct answer in the official bank: Pass only from the right. Only public transportation is allowed to pass from the left as well.

The white arrow tells vehicles to pass on the right, so a commercial vehicle must pass on the right. The yellow arrow shows that only public transportation is allowed to pass on the left as well. This is not a free choice of side for every driver, and you cannot pass on the left only.
