What kind of behaviour must you anticipate from cyclists?

The selected combination is correct because it reflects the various behaviors and issues that can arise with cyclists on the road, which are important for drivers to anticipate for safety reasons.

1. Cyclists may ride on one-way roads in both directions, meaning that they might not adhere strictly to the designated flow of traffic, creating potential conflicts with vehicles.
2. Cyclists using the wrong side of cycle paths is another common occurrence, which poses a risk of head-on collisions with vehicles or other cyclists.
3. Lack of lights when it is dark is a significant safety concern, as it reduces visibility and increases the chances of accidents.

These behaviors are critical to consider under German traffic laws, emphasizing the need for drivers to be alert and cautious around cyclists to prevent accidents and ensure everyone's safety on the roads.
