What does a downward green arrow lane use signal indicate to drivers?

A downward green arrow lane use signal indicates that drivers are permitted to use the lane beneath the green arrow. It signifies that the lane is open for travel, allowing vehicles to proceed without any restrictions. This signal provides clear guidance that it is safe to enter and use that lane, facilitating smooth traffic flow.

In contrast, other traffic signals may indicate restrictions or caution, but a downward green arrow is a clear and direct indication to drive normally in that lane.
