The vehicle ahead has prevented you from overtaking for some time now. What is the right course of action?

Your choice to wait until you are able to safely overtake is correct because German traffic rules emphasize patience and safety in such situations. If the vehicle ahead is preventing you from overtaking, you must not close the gap aggressively or use your horn and headlights persistently to pressure the other driver. Such behavior can lead to dangerous situations and is considered aggressive driving.

Instead, maintain a safe following distance and only overtake when it is legal and safe to do so, ensuring clear visibility and no oncoming traffic. This approach helps prevent accidents and respects other drivers' right of way. The rule is to avoid forcing or rushing an overtaking maneuver, prioritizing safety and proper timing.
