- No right-of-way in the next square.
Why this is the answer
The correct answer in the official bank: Roundabout ahead.
A triangular sign with a red border is a warning sign. It announces in advance that there is a roundabout ahead, so you can slow down and prepare to enter it. The sign only warns: it does not say who gives right-of-way, and it does not tell you to cross the roundabout from a particular side.
