A car breaks down on a motorway (autoput) at night. Besides putting on the reflective vest and placing the warning triangle at the prescribed distance behind the vehicle, what additional mandatory step applies under ZOBS BiH?

1. Switch on the hazard warning flashers (all direction indicators), and moving occupants to safety off the carriageway is essential
2. Switch off all vehicle lights to avoid dazzling oncoming drivers
3. Place the warning triangle on the roof of the car instead of behind it
4. Wait inside the vehicle with doors locked and lights extinguished
