Are you warned in this situation of a considerable road elevation?

Description
§ 10 para. 5 of the Regulation of the Ministers of Infrastructure and 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
The warning sign A-23 'steep hill upwards' visible in the photo informs you that you are approaching a road section with a significant gradient. The T-9 plate placed below it specifies that the actual incline is 10%. According to § 10 para. 5 of the Regulation on road signs and signals, this sign warns of an incline that may cause traffic difficulties, which justifies an affirmative answer.
