What is the meaning of the sign?

- Correct answer: Move to the next lane on the right when traffic conditions allow.
- Pass the obstacle on the right side.
- Go to the right only.
- Special lane for public transport.
Why this is the answer
The correct answer in the official bank: Move to the next lane on the right when traffic conditions allow.
The sign tells you to move to the next lane on the right, but only when traffic conditions allow it, meaning the move is safe and does not disturb the vehicles in that lane. It does not tell you to pass an obstacle on the right side, it does not require you to go to the right only, and it does not mark a special lane for public transport.
