The P-9 Guiding Arrow sign is painted directly onto the road surface and indicates that your current lane is about to end, usually due to road narrowing or a lane terminating. You must merge into the adjacent lane to continue. Look for these arrows as an early warning to check your mirrors, signal your intentions, and prepare for a smooth merge into the traffic flow. In heavy traffic, the zipper merge approach is recommended near the actual merge point.
This P-9 Guiding Arrow sign indicates your current lane is ending, requiring a safe merge into adjacent traffic. Master its meaning for your theory test revision and ensure safe driving on Polish roads by understanding this crucial traffic sign explanation.
The P-9 arrow is a slanted arrow painted on the road surface. It is a critical instruction for merging traffic. It warns that the lane is terminating (e.g., a climbing lane ending or a road narrowing) and that the driver must transition to the next lane. In slow-moving traffic, the 'zipper merge' rule applies at the point where the lane actually ends following these arrows.
Commands drivers to move to the adjacent lane indicated by the arrow because their current lane is ending.

This FAQ strengthens your understanding and supports accurate decision making for the Polish driving theory exam in Poland.
The P-9 Guiding Arrow is a directional marking on the road surface that instructs you to move into the adjacent lane because your current lane is ending. It's a command, not just a suggestion, to change lanes safely before your lane disappears.
As soon as you see the P-9 arrows, start looking for a safe gap in the lane you intend to merge into. Check your mirrors, signal your intention early, and move smoothly into the continuing lane before your lane physically ends. Avoid sudden or abrupt movements.
The P-9 sign has variations: P-9a points to the left, and P-9b points to the right. Both serve the same purpose: to guide you to merge into the continuing lane by indicating which direction to move.
A common mistake is ignoring the arrows and driving until the lane physically ends, forcing an abrupt merge. Another is merging without checking mirrors or signaling. The theory exam may test your understanding of when to start preparing to merge, not just at the very last second.
Yes, the zipper merge is relevant when traffic is heavy. At the point where the lane actually ends, if traffic is slow, drivers in both the ending lane and the continuing lane should take turns merging, like teeth on a zipper. However, this applies near the merge point itself; the P-9 arrows are the earlier warning to prepare.
It is prohibited to ignore the arrow and continue until the lane ends abruptly, merge without signaling or checking mirrors, or try to overtake other vehicles in the adjacent lane just before your lane runs out. You must prepare to merge.
