What is the right course of action now?

In this situation, you chose the correct answers: slowing down to walking speed and moving as far to the right as possible. According to German traffic rules, when passing pedestrians on a narrow or rural road without a sidewalk, you must reduce your speed to walking pace to ensure their safety and create sufficient lateral distance by moving to the right. It is not allowed to simply continue driving past the pedestrian without these precautions, as this could put them in danger. This defensive driving behavior helps prevent accidents and is required by law whenever pedestrians are using the roadway, especially on rural roads with tight curves and limited visibility. Remember this approach in similar situations: always slow down significantly and give pedestrians plenty of space.
