If you drive a bus whose maximum speed limit is up to 100 km/h, what's the maximum speed at which you can drive on the road once you go past this sign?
Show the correct answer
Correct answer
B. 80 km/h.
Explanation
In the photo you can see a wide dual carriageway with two lanes in one direction, and on the right a blue sign D-8 "end of expressway". When driving a bus that meets the additional technical conditions, you may travel here at a maximum of 80 km/h - answer B.
The Road Traffic Act allows a bus that meets the additional technical conditions to travel at 100 km/h only on a motorway and an expressway. Beyond the end of expressway sign this privilege ends and you return to the ordinary limits for a bus: 80 km/h on a dual carriageway with at least two lanes in each direction, and 70 km/h on other roads. In the photo the road continues as a dual carriageway with two lanes in each direction, so 80 km/h applies. The value 70 km/h (answer A) would apply to an ordinary single-carriageway road, and 100 km/h (answer C) was allowed only before sign D-8.
Legal basis: Art. 20 para. 3 point 2 letter a and para. 4 of the Road Traffic Act (Prawo o ruchu drogowym); § 48 para. 1 of the Regulation on road signs and signals
