Are you obliged in this situation to change the lane if you continue driving?

Description
§ 87 para. 3 of the Regulation of the Ministers of Infrastructure and of Internal Affairs and Administration of 31 July 2002 on road signs and signals (Journal of Laws No. 170, item 1393, as amended).
Explanation
Correct answer: Yes
Yes, the merging arrow (sign P-9) visible on the carriageway indicates that the lane is ending and requires you to move onto the adjacent lane indicated by the arrow. Ignoring this sign and driving straight on would lead to leaving the carriageway. However, it's important to remember that when changing lanes, you must give way to vehicles already in that lane.
