In this situation, why do you have to wait before turning left?

In situations where you want to turn left and a tram is approaching from behind or from the opposite direction, you must always give way to the tram. This is because trams generally have priority over cars, regardless of other vehicles or traffic signs, unless traffic lights or police directions state otherwise. In this question, you correctly selected that you have to wait because of the tram; the other vehicles do not have priority in this specific situation. Remember: in most intersections, trams rarely stop or swerve and always have precedence when you are turning left across their tracks. This ensures safety for both the tram and other road users.
