When are you in danger when overtaking?

The combination you selected is correct because both scenarios—suddenly accelerating and swerving out to overtake—indicate that the driver is acting unpredictably, which poses a danger when you are attempting to overtake.

In German traffic law, being aware of the behavior of other vehicles while overtaking is crucial for ensuring safety on the road. These actions can lead to sudden changes in traffic dynamics, increasing the risk of collisions.

While the option regarding reducing speed considerably is a potential concern, it doesn't directly relate to the immediate danger presented during overtaking maneuvers. It's important to recognize all relevant behaviors that can create hazardous situations when driving. Understanding these dynamics helps you make safer driving decisions and ensures compliance with traffic regulations aimed at minimizing accidents.
