You break down and have to stop on the right hand hard shoulder of an autobahn. What must you do?

The steps you selected are all crucial for safety when breaking down on the autobahn.

1. Switching on your hazard warning lights alerts other drivers that your vehicle is stationary and may pose a hazard. This is a legal requirement in Germany to ensure visibility.
2. Placing warning signs at a sufficient distance behind your vehicle is also mandated by law. This gives approaching drivers an early warning to slow down and maneuver safely.
3. Ensuring that passengers stay a safe distance away from the autobahn is important for their safety. They should remain inside the vehicle if possible or move to a safe area away from traffic, especially on a high-speed road like the autobahn.

Calling for help is essential if the vehicle cannot be repaired on-site. This ensures that a professional can assist in a safe manner without further risk to yourself or your passengers. Overall, these steps follow the German street traffic regulations aimed at protecting both the vehicle's occupants and other road users.
