Do you have to exercise particular caution when approaching the stopping place of a vehicle marked in such a way?

Yes, the vehicle visible in the video is a school bus, marked with the characteristic sign with a symbol of children. According to Art. 57 para. 2 of the Road Traffic Act, a driver passing such a vehicle while children are boarding or alighting must exercise special care. This means you should slow down and, if necessary, even stop, as children can behave unpredictably and run onto the road.
