When reaching the roundabout you should
- give priority to traffic approaching from your right, unless directed otherwise by signs, road markings or traffic lights
- check whether road markings allow you to enter the roundabout without giving way. If so, proceed, but still look to the right before joining
- watch out for all other road users already on the roundabout; be aware they may not be signalling correctly or at all
- look forward before moving off to make sure traffic in front has moved off.
