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
A. 80 km/h.
Explanation
In the photo you can see a dual carriageway with two lanes in one direction, and on both sides blue signs 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 A.
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. When you pass the end of expressway sign, you lose this privilege and the same limits apply to you as to any bus: 80 km/h on a dual carriageway with at least two lanes in each direction and 70 km/h on other roads. Beyond the sign in the photo the road still has two carriageways and two lanes in your direction, so the limit is 80 km/h. The value 90 km/h (answer B) is the speed limiter setting for a lorry, not the speed for a bus, and 100 km/h (answer C) applied only on the expressway.
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
