What does a yellow X signal indicate?

A yellow X signal serves as a warning that the lane is about to be closed or is unsafe to use. It typically indicates that drivers should prepare to change lanes or exit the lane they are currently in. When you see a yellow X, it means that you should move to a lane where a green arrow is displayed, indicating that it is safe to continue. The presence of the yellow X is to alert drivers in advance, giving them time to adjust their path safely before encountering a more restrictive signal or scenario.

In contrast to the other options, which suggest actions that could lead to dangerous situations, the correct interpretation focuses on the importance of lane changes in response to the signal. For instance, stopping immediately or proceeding into oncoming traffic would not only be unsafe but could lead to accidents, highlighting the necessity of responding appropriately to the yellow X signal.
