What does a lane use control signal displaying a green arrow 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 green arrow, drivers may drive normally in the indicated lane.

• The signal is about to change to a red X.
• Drivers should not drive in this lane.
• Drivers may use the indicated lane only to make a left turn.
