Explanation
Flashing arrow panels are commonly used in work zones to provide advance warning and directional guidance, helping drivers merge into the correct lane when necessary. These panels indicate that a portion of the road ahead is closed and direct motorists to move to the right or left. When approaching a flashing arrow panel, slow down and prepare to merge in the indicated direction. If the arrow panel is flashing but does not point left or right, it signals drivers to proceed with caution without requiring a lane change.
