When does the patrol need to use their lights and sirens during a funds escort?

The correct choice indicates that the patrol should use their lights and sirens only in an emergency during a funds escort. This approach aligns with standard protocols for ensuring safety and minimizing disruption. Utilizing lights and sirens communicates urgency and alerts other road users to yield or clear the way, which is particularly important in emergency situations where speed may be critical to ensure the safety of those involved and the security of the funds being transported.

In non-emergency situations, activating lights and sirens may lead to unnecessary panic or confusion within the public, as well as potential distractions for drivers. Such measures are typically reserved for scenarios where immediate action is needed, thereby prioritizing safety and compliance with established operational procedures.
