You witness a pedestrian being run down. How should you behave?

As a witness to an accident, you have a legal and moral duty to provide assistance. You should stop in a safe place, secure the scene (e.g., by switching on your hazard warning lights), call the emergency services (number 112), and, if possible, administer first aid to the injured person. Failure to provide assistance to a person whose life or health is in danger is a criminal offence.
