You have an accident on the autobahn with your truck. In which order do you proceed?

You answered correctly. In the event of an accident on the autobahn, your first steps must be to stop immediately, ensure that the scene is safe to prevent further accidents, and then check for injured persons to provide help if needed. German traffic law prioritizes safety and assistance to those involved before anything else. Ensuring traffic safety includes warning other drivers, for example by setting up a warning triangle or activating hazard lights, and only afterwards should you gather information or take further administrative steps. This order helps prevent more harm and fulfills your legal obligation to provide assistance. Remember: safety first, then help injured people.
