What do lane signals with a 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 signal contains a yellow X, drivers should clear the indicated lane, as the lane signal is about to change to a red X.

• The signal is about to change to a green arrow.
• The signal is about to change to a red X.
• Drivers may drive normally in this lane.
• Drivers may drive slowly in this lane.
