The bus is pulling out from the stop. Is it compulsory to let it through?

In built-up areas, to facilitate the movement of collective passenger transport vehicles, drivers of other vehicles must move laterally whenever possible, or reduce their speed whenever they can do so without risk and without doing so abruptly, signalling with the regulatory signals, and even stopping if necessary, so that collective transport vehicles can carry out the manoeuvre needed to continue on their way when leaving designated stops.
