What does a "Left Turn Yield on Green" sign indicate?

A "Left Turn Yield on Green" sign indicates that while drivers can make a left turn when the traffic signal is green, they must yield to oncoming traffic. This warning is crucial as it alerts drivers that they are permitted to turn left but must do so only when it is safe and without interfering with vehicles coming from the opposite direction.

This type of sign is often found at intersections where left-turning vehicles have the opportunity to move while the light is green, but the presence of oncoming traffic could create unsafe conditions if drivers do not yield. It is an important traffic rule that helps prevent collisions and ensures that the intersection operates smoothly, allowing both turning vehicles and oncoming traffic to navigate safely.

The other options do not accurately represent the intended meaning of the sign, as they either suggest restrictions or behaviors that conflict with the concept of yielding, which is essential for safe left turns at such intersections.
