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.
The F-16 sign, signaling the end of a lane on a two-way road, demands immediate attention to ensure safe merging into the adjacent lane.

The F-16 sign is used on roads with at least two lanes in one direction to warn that the leftmost lane (the inner lane) is coming to an end. Drivers in that lane must merge into the right-hand lane. In Poland, the 'zipper merge' (jazda na suwak) rule applies here: drivers in the continuing lane must allow one vehicle from the ending lane to merge in front of them if traffic is slow or at a standstill.

The D-2 sign officially cancels the priority status previously granted by the D-1 sign. It appears as the standard yellow diamond but is crossed out with a thick black diagonal line. This sign is usually placed before an intersection with another priority road, an equal-priority intersection (where the 'right-hand rule' applies), or a roundabout.

This requires the 'zipper merge' technique (jazda na suwak) in congested traffic, where drivers from the ending lane should be allowed to merge one by one into the continuing lane.
