When turning left at an intersection, what must you do?

When turning left at an intersection, yielding to all oncoming traffic is essential for ensuring safety. This is because as you turn left, you may directly cross the path of vehicles coming from the opposite direction. By yielding, you allow these vehicles to pass safely, avoiding potential collisions. This practice aligns with traffic laws and helps maintain the flow of vehicles at the intersection.

Turning left without signaling or failing to yield, regardless of the presence of other vehicles, can lead to confusion for other drivers and increase the risk of accidents. Additionally, speeding up to make the turn quickly is not a safe practice, as it can compromise control of the vehicle and reduce the driver's ability to react to unexpected situations. Proper yielding is critical to safe navigation through intersections.
