Police Standards and Training Council (PSTC) Practice Test

An active bystander is someone who doesn’t just witness a situation but steps in to prevent harm or protect someone. The best description is someone who steps forward, speaks up, and takes action. That combination shows real-time intervention—using your voice to deter inappropriate behavior, and taking steps to address the situation or get needed help. It embodies proactive protection rather than passivity.

Remaining silent and observing is passive and doesn’t stop anything. Documenting the incident after it ends is about recording what happened, not preventing or interrupting it in the moment. Leaving the scene avoids involvement and can allow harm to continue.
