You are on a road outside of a built-up area, and a car in front of you is driving much slower than is permitted to and has the capacity to. What is the right course of action?

In this situation, you are driving on a road outside of a built-up area and encountering a car that is driving significantly slower than allowed.

The correct actions involve adjusting your speed to match that of the slower vehicle and overtaking it in a safe manner when conditions allow.

Adjusting your speed is necessary for safety; you must maintain a safe following distance without exceeding speed limits. Overtaking is permitted where the road and circumstances allow it, as long as you do so safely and legally.

Flashing headlights at the slower car is not considered a proper or courteous action and can be interpreted as aggressive. In German traffic regulations, communication should not involve intimidating behaviors.

Thus, both adjusting your speed and overtaking when appropriate are the correct responses to ensure safety and compliance with traffic regulations.
