Does this sign warn of a road section where you must exercise particular caution due to ruts on the surface of the road?

Description
§ 11 para. 1 and para. 2 pt. 5 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 warning sign A-30 "other danger" along with the plate T-13 with the inscription "Ruts" warns of a deformation of the road surface. The additional plate T-2 informs that the dangerous section will last for 2.4 km. In such a situation, you should exercise particular caution and adjust your speed, as driving in ruts, especially during rain, can risk losing control of the vehicle.
