Correct answer
C. 100 km/h.
Explanation
In the photo you can see a motorway with noise barriers and a flyover, and next to it signs D-9 "motorway" on both sides. When driving a bus that meets the additional technical conditions, you may travel here at a maximum of 100 km/h - answer C.
The Road Traffic Act states that the speed limit for a bus that meets the additional technical conditions set out in the regulations is 100 km/h on a motorway and an expressway. Meeting these conditions is confirmed by an additional technical inspection - without it a bus may travel on a motorway at only 80 km/h. The values 140 km/h (answer A) and 120 km/h (answer B) are the limits for passenger cars on a motorway and on a dual-carriageway expressway, and they never apply to a bus; in addition, a bus should have a speed limiter set to 100 km/h. Outside a motorway and an expressway such a bus is subject to the ordinary limits.
Legal basis: Art. 20 para. 3 and 4 and Art. 66 para. 1a of the Road Traffic Act (Prawo o ruchu drogowym)
