What are signs of a suicidal person on or near the tracks?

The correct choice indicates that erratic behavior, standing too close to the tracks, or displaying signs of distress are significant indicators of someone who may be contemplating suicide. Each of these behaviors reflects a heightened state of emotional turmoil or an urgent need for intervention.

Erratic behavior can include unpredictable or unstable actions that may put the individual's safety at risk, especially in dangerous environments such as train tracks. Standing too close to the tracks poses a clear physical danger and suggests a disregard for personal safety, which can be a sign of suicidal thoughts. Displaying signs of distress—such as crying, withdrawal, or agitation—can indicate severe emotional pain or hopelessness. Being attentive to these signs is crucial for bystanders to provide support or alert authorities in order to prevent tragedies.

The other behaviors listed, such as waving at trains, taking photographs, or wearing headphones, typically do not suggest suicidal intent. Instead, they may reflect a lack of awareness or engagement with the surrounding environment. Reading a book or sitting calmly also implies a sense of peace or distraction, which is generally contrary to the signs associated with someone in a crisis situation. Recognizing the more serious signs outlined in the correct option is essential for early intervention and potentially saving a life.
