The F-16 'End of Lane (Two-Way Road)' sign is a warning sign informing you that the inner (left) lane in your direction of travel is about to end. This is common on multi-lane roads, and it signals the need to merge into the right-hand lane. In Poland, the 'zipper merge' rule (jazda na suwak) is crucial here: drivers in the continuing lane must allow vehicles from the ending lane to merge smoothly if traffic is slow or stopped. Always check your mirrors and signal your intentions early.
