Is it prohibited to overtake a rail vehicle in this situation?

In the video you are driving along a street in a town in the lane to the right of the tram tracks, going through a junction with traffic lights on a green light; on the left, on the tracks in the middle of the roadway, a tram is travelling in the same direction. Overtaking the rail vehicle is not prohibited here. The answer is: no.

The Road Traffic Act states that a rail vehicle may be overtaken only on the right, unless the position of the tracks makes this impossible or the overtaking takes place on a one-way roadway. So the rule does not prohibit overtaking a tram - it only sets the side from which you do it. The tracks run down the middle of the roadway and you are driving on the right of the tram, so overtaking on the right is exactly what the Act provides for. It would be prohibited to overtake the tram on the left, across the tracks and the lane for the opposite direction, and to overtake where the Act prohibits overtaking any vehicle - on a pedestrian crossing without traffic lights or on a level crossing; here traffic is controlled by traffic lights. During the manoeuvre you remember two things: at a stop without a traffic island you stop when the tram is standing at the stop or pulling into it, so that the passengers can reach the pavement.
