You are driving on a rural road. A line of approximately 15 slow-moving vehicles is travelling in front of you. What should you do?

In this situation, the most appropriate action according to German traffic rules is to remain behind the line of vehicles for the moment. This is because overtaking can be dangerous, especially in rural areas where visibility may be limited and other vehicles could be approaching. Flashing lights and sounding the horn to urge others to overtake is not advisable, as it can create panic or dangerous situations.

The key points are:

1. Safety: Always prioritize safety over impatience. Remaining behind the line allows you to assess conditions safely before deciding to overtake.
2. Legal considerations: Overtaking in inappropriate situations may constitute a violation of traffic laws, which are designed to prevent accidents and ensure a safe flow of traffic.
3. Patience: Sometimes, it is simply best to wait until a safe opportunity arises for overtaking, rather than trying to urge others to move faster.

In essence, understanding patience and safety on the road is crucial in following traffic regulations effectively.
