What does a green arrow indicate in lane usage?

A green arrow in lane usage indicates that the lane is safe to travel. This signal is often used at intersections or in lanes where vehicles can proceed in the direction the arrow points. It effectively communicates to drivers that they have the right of way and can safely maneuver through that lane without concern for obstacles or restrictions.

This clear indication helps to prevent confusion and ensures smoother traffic flow by allowing drivers to understand that it is permissible to continue driving in that direction. In contrast, signals such as red lights or signs would indicate warnings or restrictions, highlighting the importance of the green arrow as a marker for safe travel.
