In your rear-view mirror, you see the words "STOP POLIZEI" (Stop Police) in red illuminated letters on the roof of a police car immediately behind your car. Who does this apply to?

The "STOP POLIZEI" signal indicates a directive specifically aimed at the vehicle it is directly behind, which is you. According to German traffic laws, when a police vehicle signals you to stop, it primarily applies to your vehicle. However, it is also crucial for surrounding vehicles to acknowledge the situation, as they must be aware of the potential for your vehicle to stop suddenly and the police's request for compliance.

This directive helps maintain order and safety on the road, ensuring that law enforcement can perform their duties effectively without interference. Thus, while the primary instruction is for you alone, other drivers must also remain alert and adjust their actions accordingly, making it important to consider the broader context of traffic rules regarding police authority and public safety.
