Are you obliged, in this situation, to ensure that no other vehicle is approaching from the lane you intend to drive into?

The intention to change lanes, in this case to pass a bus stopped at a bus stop, requires the driver to exercise particular caution. The fundamental element of this caution is to make sure that there are no other vehicles in the lane the driver intends to enter to which, according to the regulations, they must give way. The manoeuvre cannot be performed safely without checking the situation in the adjacent lane.
