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

- Enter the roundabout carefully since you have right-of-way.
- Pay attention to traffic coming from your right within the roundabout.
- Stop before entering the roundabout and cross it quickly.
- Correct answer: Slow down before the roundabout.
Why this is the answer
The correct answer in the official bank: Slow down before the roundabout.
This warning sign tells you a roundabout is ahead, so you should slow down in good time. Drivers entering a roundabout must give way to vehicles already circulating in it, so be ready to stop if needed. You do not have right-of-way when entering, and circulating traffic approaches from your left, not your right.
