When we see a driver attempting to join the flow of traffic, we must facilitate the manoeuvre as much as possible, especially if it is a bus intending to merge from a designated stop.

Within built-up areas, in order to facilitate the movement of collective passenger transport vehicles leaving designated stops, drivers of other vehicles must:

- move laterally when possible,
- reduce their speed, provided they can do so without risk, without abruptness and signalling it correctly, and
- stop, if necessary, so that the bus can merge into traffic.
