What does a traffic signal with a "YELLOW LEFT ARROW" indicate to the driver?

A traffic signal displaying a yellow left arrow serves as an important signal to drivers intending to turn left. Specifically, it indicates that the protected turning phase for left turns is about to end, and drivers should prepare to yield to oncoming traffic and pedestrians. The yellow left arrow warns that soon the light will change to red, meaning drivers must exercise caution and be ready to stop if needed. It is crucial for ensuring safety by allowing drivers to make left turns while being aware of potential conflicts with vehicles and pedestrians that may be crossing their path. This signal is designed to promote safe and orderly traffic flow while ensuring that all road users are adequately informed of the changing conditions.
