In the presented situation, can you resume driving only after the tram has moved off?

In the video, you are driving along a street with tram tracks; on the left, on the track for the opposite direction, a tram is standing at a stop without a traffic island, and passengers who have got off it are crossing the roadway on the marked pedestrian crossing with sign D-6 and plate T-27 to the pavement on the right. You must stop the vehicle and let the pedestrians cross, but you do not have to wait until the tram moves off - you continue when the pedestrians have safely left the roadway. The answer is: no.

The Road Traffic Act requires you to give way to a pedestrian who is on a crossing or stepping onto it, and at a stop without a traffic island to stop the vehicle for as long as needed to let pedestrians walk freely to the tram or onto the footway (droga dla pieszych). So what matters is the safety of pedestrians, not the departure of the tram. You stay where you are as long as anyone is crossing; when the roadway is empty, you move off slowly, watching the tram doors.
