What are the regulations governing speed when overtaking?

The selected combination is correct because it reflects essential regulations for overtaking on German roads, ensuring safety and order.

1. The requirement that the speed of the overtaking vehicle must be appreciably higher ensures that the overtaking process is completed quickly and safely, minimizing the time spent in the opposing lane.

2. Adhering to the permissible top speed ensures compliance with traffic laws, which are designed to maintain safety on the roads.

3. The rule stating that the person being overtaken must not increase their speed is crucial because it helps prevent dangerous situations where both vehicles might accelerate, creating potential for accidents.

Together, these rules minimize risks and maintain a systematic flow of traffic during overtaking maneuvers. Understanding and applying these regulations is important for the safety of all road users.
