At an intersection with a safety sign permitting U-turns, you want to make a U-turn on a green light. Car A is coming straight toward you from the opposite direction. Which TWO are correct? Select TWO

• Your car (blue) is in lane 1 with the left signal on, about to make a U-turn
• Green light ahead
• Car A is coming straight from the opposite direction

1. ①Because a U-turn sign is present, your U-turning car has priority over car A.
2. ②Sound the horn so car A stops, and make the U-turn first.
3. ③Move to lane 2 so you can turn wider, then make the U-turn.
4. ④A U-turn now may obstruct car A's normal passage, so make it after car A has passed.
5. ⑤Keep the left signal on until the U-turn is finished.
