Manoeuvres and parking that create danger or obstruction

Before turning right, move towards the right-hand edge rather than the left. Signal every change of direction in sufficient time, and never park on tram tracks because this obstructs tram traffic. Speed contests and driving too slowly without a justified reason also create danger or obstruction. Safely joining from a side road, adapting speed to road conditions and briefly stopping along the right edge of a one-way carriageway are not inherently prohibited when no other rule or hazard prevents them.
