Correct answer
B. 80 km/h.
Explanation
In the photo you are driving on a dual carriageway, and on the right there is sign D-9 "motorway". In a passenger car with a trailer, which is a vehicle combination, you are allowed to drive on a motorway at a maximum of 80 km/h - answer B. The 140 km/h limit (C) applies to a passenger car without a trailer, and 70 km/h (A) applies to vehicle combinations on ordinary roads.
The Road Traffic Act states that the speed limit for a vehicle combination on a motorway, an expressway or a dual carriageway with at least two lanes in each direction is 80 km/h, and on other roads 70 km/h. A trailer increases the braking distance and at high speed it starts to sway from side to side, which is why the limit is lower. The Regulation on road signs and signals specifies that D-9 marks the beginning or continuation of a motorway.
Legal basis: Art. 20 para. 3 point 2 letter a of the Road Traffic Act (Prawo o ruchu drogowym); § 48 para. 2 of the Regulation on road signs and signals
