What should you do when entering a roundabout or traffic circle?

1. Enter quickly without yielding because motorcycles have priority over vehicles already circulating in the roundabout
2. Yield as required to traffic already in the circle and choose a safe gap
3. Stop inside the circulating lane to read the exit signs whenever the intended route is uncertain
4. Ride beside a larger vehicle in the same lane so it blocks crosswinds while both vehicles exit together
