You are approaching a roundabout in fog. Visibility is reduced, traffic may already be circulating, and your exit is the third exit. What is the safest combined approach?

1. Use high beams and enter quickly so you do not stop
2. Drive with hazards on and change lanes inside the roundabout
3. Follow the nearest vehicle closely through the roundabout
4. Slow early, use the correct lane, avoid overtaking, yield to circulating traffic from the left, and keep extra space
