What's the maximum speed at which you can drive a passenger car on a road marked with this sign?

Description
§ 58 para. 3 of the Regulation of the Ministers of Infrastructure and of the Interior and Administration of 31 July 2002 on road signs and signals (Journal of Laws No. 170, item 1393, as amended) and art. 20 para. 3 pt. 1(d) of the Act of 20 June 1997 – the Road Traffic Act (Journal of Laws of 2012, item 1137, as amended)
Explanation
Correct answer: 90 km/h.
The D-43 "End of built-up area" sign cancels the 50 km/h speed limit. You are entering a single-carriageway, two-way road outside a built-up area. According to Art. 20 of the Road Traffic Act, the maximum permitted speed for a passenger car on such a road is 90 km/h.
