What must a bus driver do if an emergency requires complete evacuation of all passengers along a high-speed motorway?

1. Pull onto the hard shoulder or emergency bay, turn on hazard lights, set parking brake, instruct passengers to disembark calmly through the right-side doors, guide them immediately behind the metal crash barrier (Leitplanke), move upstream away from the bus, and set up the breakdown triangle at least 100 meters behind
2. Tell passengers to run across the active motorway lanes
3. Tell passengers to stand directly behind the bus on the roadway
4. Lock all passengers inside the smoking bus
