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

1. Correct answer: Give right-of-way to traffic crossing your path on the roundabout,
2. Drive right or left. A yellow arrow shows the direction of driving for public transportation only.
3. When you are driving in the roundabout, give right-of way to vehicles that approach the roundabout from its different ‘arms’.
4. Pass the place that is marked with a signpost from its left only.

WhySign 303 requires you to give way to traffic in the roundabout and drive around it to the right. You do not take priority over those already going around.
