When performing a legal U-turn at an intersection, what right-of-way duty does the turning driver have?

1. The driver has priority over all other vehicles.
2. The driver must yield right-of-way to oncoming vehicles going straight or turning right, and to intersecting traffic that has green light.
3. The driver only yields to pedestrians on the left.
4. The driver is exempted from yielding if the U-turn is done in a single continuous movement.
