Who is parked?

Your selection of answer choices is correct as it aligns with German traffic regulations. According to the German Road Traffic Regulations (StVO), anyone who stops for more than 3 minutes is considered parked. This includes vehicles left unattended, which is covered by the second option. The third option regarding waiting at a closed level crossing barrier is also relevant, as this situation typically indicates a stop that may lead to parking if prolonged.

These definitions are crucial for understanding parking rules, especially in terms of legality and safety. It is important to recognize that all three situations contribute to what constitutes parking under German law, ensuring that drivers are aware of how long they can stop and when it becomes illegal or unsafe.
