If traffic sign 618 is placed at an entry to a road, which traffic sign should be placed at the entry from the opposite side of the same road?

- 308
- 401
- 307
- Correct answer: 402
Why this is the answer
The correct answer in the official bank: 402
Sign 618 marks a one-way road, where traffic flows in one direction only. From the other end of the same section, driving in would mean driving against the flow of traffic. So sign 402, which prohibits entry for all vehicles, is placed there. Signs 307 and 308 deal with right of way at a narrow place, and sign 401 prohibits traffic in both directions.
