When is it required to yield to the right of way?

Yielding the right of way is crucial for ensuring safe navigation through intersections, especially when turning left. When you're turning left at an intersection and there is oncoming traffic, the vehicles coming toward you have the right of way. It's essential to wait for a safe gap in oncoming traffic before completing your turn. This practice helps prevent collisions and ensures the flow of traffic is maintained.

Merging onto a highway typically requires yielding to traffic already on the highway, but the right of way in that scenario primarily pertains to the oncoming vehicles on the highway rather than the specific scenario provided in the question. Similarly, when coming to a stop sign, you must stop and yield to vehicles with the right of way, but the question specifically asks about situations that require yielding, which in this case, is most relevant to left turns at intersections. When approached by an emergency vehicle, it's important to yield as well, but since the question pertains specifically to turning at intersections, the left turn situation is the most direct answer regarding right of way rules.
