If you drive a bus that meets the additional technical conditions, what’s the maximum speed at which you can drive on the road once you go past this sign?

Explanation
Correct answer: 100 km/h.
The visible sign D-9 "autostrada" informs of the start of a motorway. According to the Road Traffic Act, the maximum permitted speed for a bus on this type of road is 100 km/h, provided that the vehicle meets the additional technical conditions specified in these regulations. If these conditions are not met, the maximum speed would be 80 km/h.
