Why is it important for drivers to pay attention to yellow arrow signals?

Paying attention to yellow arrow signals is crucial for drivers because these signals indicate that the green arrow protection is ending. When a yellow arrow appears, it serves as a warning that the protected turn period is about to close, prompting drivers to prepare to stop or proceed with caution. This is particularly important in intersection scenarios where vehicles may have been cleared to turn based on the green arrow.

Ignoring a yellow arrow could lead to accidents since it suggests that the right of way is shifting, and a red light may soon follow, thus requiring drivers to yield to oncoming traffic or pedestrians. Understanding the significance of the yellow arrow assists in making safe driving decisions and maintaining traffic flow in busy areas.
