Does this sign placed in the area of an intersection refer only to the roadway by which it has been placed?

Description
§ 22 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 prohibition sign B-21 "No left turn" applies only to the nearest carriageway by which it is placed. In the situation visible in the picture, we are dealing with a dual carriageway, and the sign located by the right-hand carriageway does not apply to the left-hand one. Such placement of the sign allows for a different traffic organisation for each direction.
