Show the correct answer
Correct answer
A. 100 km/h.
Explanation
In the photo a white bus is standing, and next to it you can see a speedometer dial. The type-approved speed limiter in a bus does not allow it to exceed 100 km/h - answer A.
The Road Traffic Act requires vehicles of categories M2 and M3, that is buses, to have a type-approved speed limiter that limits their speed to 100 km/h. The value of 90 km/h (answer B) applies to lorries of categories N2 and N3, and 85 km/h (answer C) does not appear in this rule. Remember that the limiter is a technical barrier, not permission to drive fast: an ordinary bus may drive on a motorway at no more than 80 km/h, and 100 km/h is allowed only for a bus that meets additional technical conditions, and only on a motorway or an expressway.
Legal basis: Art. 66 para. 1a and Art. 20 para. 3 point 2 and para. 4 of the Road Traffic Act (Prawo o ruchu drogowym)
