About Equal-rank junction: no sign, but still a rule: which statement is WRONG?
Braking decides nothing; the tram goes first, then the rechts-regel.
At an equal-rank junction there must be a 'priority from the right' sign, otherwise the rule does not apply.
Drivers must give way to trams, 'regardless of which direction the tram comes from'.
The rechts-regel speaks of 'drivers coming from the right'; pedestrian crossing behaviour is governed by other rules (priority at crossings), not by this atom's rechts-regel.
Explanation
trap: sign reflex. Book p.105 - 'At equal-rank junctions there are no signs or markings that regulate priority.' No sign is precisely the defining feature of this junction type; the rechts-regel then applies automatically, without any sign
