Should an adult person transported in a bus, sitting in a seat equipped with safety seat belts, use such seat belts?

In the photo you can see the inside of a coach with rows of seats, and on the side windows blue mandatory signs requiring seat belts to be fastened. An adult passenger sitting in a seat fitted with seat belts must use them - answer A.

The Road Traffic Act requires the driver of a motor vehicle and a person carried in such a vehicle fitted with seat belts to use the belts during the journey. A bus is a motor vehicle, so the obligation also applies to coach passengers - there is no exception for buses (answer C). Nor does it depend on whether there are other seats in front of the given place (answer B): in sudden braking or if the bus rolls over, an unbelted passenger hits the seat in front or the windows, or is thrown out of their seat. The signs on the windows remind passengers of this obligation, and the bus driver must inform passengers about it, unless this has been done by the tour guide, a recording or a sign at each seat.
