Which statement about tertiary callers is true?

Tertiary callers are individuals who may have information related to an incident but did not witness it directly. They often collect information from various sources and relay that information rather than providing firsthand accounts. This means their contributions can be valuable in understanding the broader context of an incident, even if they did not observe the events themselves. Their role typically involves gathering insights or reports from others and synthesizing that information for responders or authorities. This distinguishes them from primary and secondary callers, who may have more direct involvement or firsthand observations of the incident.

The other statements about tertiary callers do not accurately reflect their role. For instance, they are not necessarily confused or unhelpful. While confusion can occur during emergencies, tertiary callers can still provide valuable information derived from others. Their involvement does not typically involve direct engagement with authorities, as they are more in the role of information gatherers rather than being the primary witnesses who interact directly with law enforcement or emergency responders.
