What does a lane use control signal displaying a solid yellow X above a reversible lane indicate?

Lane use control signals are used when the direction of the flow of traffic in a specific lane changes throughout the day. They are used to show which lanes of traffic are open and closed, as well as to show if toll booths are open or closed. When a lane control signal contains a solid yellow X, drivers should clear the indicated lane, as the lane signal is about to change to a red X.
