In an intersection with a red light, turning left and oncoming traffic has no signal, which vehicle should proceed first?

Answer: A — Car B

The main idea is how right-of-way works when one direction is turning left and the opposing direction isn’t controlled by a signal. When you turn left, you must yield to oncoming traffic; you proceed only when there is a safe gap. If the oncoming traffic has no signal and there’s a moment when it’s safe for the left-turning vehicle to complete the turn, that left-turning vehicle goes first. In this scenario, Car A is able to move first because it can clear the intersection without risking a collision with the unregulated oncoming traffic, keeping everyone moving safely. If there isn’t a safe gap, both would wait or the situation would require waiting for a signal change or other cues.
