In this situation, can you change lanes immediately before the intersection?

In the photo you are approaching a junction; before it, on both sides, there are signs F-6 warning of two-way traffic on the intersecting road, and further on D-1 with a plate; on your roadway there are two lanes with left arrows, separated by solid line P-2. In this situation you do not have the right to change lanes immediately before the junction. The answer is: no.

The Regulation on road signs and signals states that marking P-2 "single solid line" separates lanes going in the same direction and means that crossing the line and driving on it are prohibited. The solid line before a junction is intended precisely to prevent sudden lane changes at a place where drivers are looking at the junction and not in their mirrors. You choose your lane earlier, on the section with the broken line, according to the arrows and signs; if you made a mistake, you drive according to the arrow in your lane and make a U-turn further on.

Legal basis: § 86 para. 3 and § 70 para. 2 of the Regulation on road signs and signals; Art. 22 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
