What must you note when overtaking the cyclists in this situation?

Your answer is correct because both points 1 and 2 are important for safely overtaking cyclists in this situation.

The incline can cause cyclists to sway more than usual as they pedal uphill, which means you need to be extra cautious and give them enough space. This is why point 1 is important: you must take into account that the cyclists may not maintain a perfectly straight line.

Point 2 requires you to leave at least 1.5 meters of side clearance when overtaking cyclists. This extra buffer helps prevent accidents caused by unexpected movements from the cyclists and ensures their safety.

Point 3 (1.0 m clearance) is insufficient, especially considering the possibility of swaying on an incline. German traffic rules specify this larger minimum distance when overtaking bicycles to protect vulnerable road users.

In summary, always consider possible cyclist swaying on inclines and maintain a wide safety margin of at least 1.5 meters when overtaking. This ensures you give cyclists enough room and respect their safety.
