You are overtaken by a police vehicle, which pulls in immediately in front of you. The words "BITTE FOLGEN" (PLEASE FOLLOW) appear illuminated in red on the roof. To whom does this apply?

The illuminated sign "BITTE FOLGEN" (PLEASE FOLLOW) on a police vehicle is directed specifically at the driver immediately behind the police car—so it applies only to you. This instruction is not meant for all vehicles in your lane or for other emergency vehicles that may be behind; only the driver right behind the police car must follow the order. In such a situation, you must carefully and promptly follow the police vehicle as instructed, as this is a direct command to you. Knowing this helps you respond correctly in similar scenarios on the road.
