What does a lane use control signal displaying a flashing yellow X 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 flashing yellow X, drivers may use the indicated lane only to complete a left turn.

• The signal is about to change to a red X.
• The signal is about to change to a green arrow.
• Drivers may only use the indicated lane to make a left turn.
• Drivers may drive slowly in the indicated lane.
