If a driver's answers are unacceptable, what should you do?

In situations where a driver's answers are deemed unacceptable, holding everyone in their current positions and calling for support is the most appropriate response. This approach ensures the safety and security of all involved while seeking further assistance or clarification on the situation.

By maintaining control over the scene, you can prevent any potential escalation or flight risk from the driver or other occupants. Calling for support means that you can involve law enforcement or additional security personnel who are trained to handle such situations effectively, thereby ensuring that proper protocol is followed and everyone’s safety is prioritized.

The other options would either compromise the scene's integrity, potentially allowing a suspect to leave without proper investigation or response, or would lead to unnecessary escalation or legal complications without the appropriate authority present.
