What does it mean if a traffic light is green with a yellow arrow?

A traffic light displaying a green light with a yellow arrow indicates that you are allowed to make a turn in the direction of the arrow. However, the yellow color serves as a warning, suggesting that you should approach the turn with caution. This typically means you should check for pedestrians crossing and be aware of any vehicles that may also be in the area, making sure it is safe to proceed.

The yellow arrow essentially alerts drivers that while they can turn, they need to do so carefully as the light is about to change, and there may be other traffic that could pose a risk. The requirement to yield to pedestrians and other vehicles is essential to ensure safety and prevent accidents at intersections.
