Step-by-step explanation:
When a vehicle is waiting to turn left in front of you, crossing your path, it is called an oncoming left turn. This is a common scenario at intersections where one vehicle wants to turn left while another vehicle is approaching from the opposite direction. In this situation, the vehicle turning left should yield to the oncoming traffic before making the turn. By yielding, the turning vehicle allows the oncoming vehicle to pass safely before completing its turn.
