What must you check at the emergency exits before setting off?

Your selection was correct because both points 1 and 2 are crucial for ensuring safety at emergency exits.

1. Checking if the emergency exits have the necessary devices for opening ensures that passengers can exit quickly during an emergency. This is in line with safety regulations that mandate operational emergency exits.

2. Verifying that these exits are not obstructed by luggage or other objects is vital since blockages can delay or prevent evacuation, posing serious risks in emergencies.

Together, these checks help to ensure that all passengers can safely evacuate in case of an incident, adhering to German traffic safety laws that emphasize passenger safety and emergency preparedness.
