Which of the following three vehicles is not in the correct lane, according to the traffic sign?

- All three are driving according to the law.
- Correct answer: The light (private) vehicle (1).
- The fire-engine (2).
- The purple pickup truck (3).
Why this is the answer
The correct answer in the official bank: The light (private) vehicle (1).
The blue sign on the traffic island requires you to pass to the right of it. The light private vehicle (1) passes to the left of the island and the sign, so it is in the wrong lane. The purple pickup truck and the fire-engine pass to the right of the sign, as it instructs.
