In a reversible lane, what does a green arrow displayed above the lane tell you?
- The lane may be used in the direction shown
- The lane is reserved for buses
- The lane is changing and must be vacated
- The lane is closed to all traffic
Answer: The lane may be used in the direction shown. Reversible lanes change direction at different times, so drivers must read the overhead indication before entering. Montana describes a green arrow as permission to use the lane beneath it. A bus reservation is a separate control, and a changing-lane warning uses a steady yellow X. A red X closes the lane, so it is not interchangeable with the green arrow. Check the display again if conditions or lane controls change.
