You are the first person to arrive at the scene of an accident with injured persons. What should you do first as a rule?

In the event of an accident with injuries, the first priority is to ensure safety at the scene. This includes making the scene safe to prevent further accidents or injuries. According to German traffic regulations, it's essential to secure the area, which may involve using warning triangles and ensuring that your vehicle is positioned safely.

After ensuring safety, you can then assess the seriousness of the injuries. It's crucial to know what kind of help is needed. Finally, you would call for emergency services, providing them with clear information about the situation.

The correct approach combines these steps because each contributes to the effective management of the situation. Safety first prevents additional harm, assessing injuries ensures the right level of care, and contacting emergency services is vital for professional assistance. Each step is interlinked and essential for a comprehensive response to an accident.
