You intend to drive into the left lane. Do you have the right of way over the vehicles driving in it?

In the photo you are driving in the right lane, which is about to end - lane-change arrow P-9 on the roadway directs you into the neighbouring left lane, where other cars are already driving. When entering the left lane, you give way to the vehicles travelling in it. The answer is: no.

The Road Traffic Act says that a driver changing lanes must give way to a vehicle travelling in the lane they intend to enter. The Regulation on road signs and signals explains that P-9 "lane-change arrow" means an order to move into the neighbouring lane shown by the arrow. The zipper merge (jazda na suwak) works only in a traffic jam, when speed is greatly reduced - in normal traffic you switch on your indicator and wait for a gap.

Legal basis: Art. 22 para. 4 and 4a of the Road Traffic Act (Prawo o ruchu drogowym); § 87 para. 3 of the Regulation on road signs and signals
