What are you required to do according to the following road sign?

- Stop before the signpost.
- Give right-of-way to vehicle traffic in the roundabout.
- Correct answer: Prepare to stop your vehicle at the nearest junction.. Stopping at the junction is obligatory
- Prepare to stop the vehicle in about 300 meters.
Why this is the answer
The correct answer in the official bank: Prepare to stop your vehicle at the nearest junction.. Stopping at the junction is obligatory
This warning sign tells you in advance that a stop sign is ahead. Slow down and get ready to come to a full stop at the junction where the stop sign stands, because stopping there is obligatory. You do not stop at the warning sign itself, and it does not set an exact distance such as 300 meters.
