What best describes a nonemergency response during normal operations?

A nonemergency response during normal operations is characterized by the absence of lights and sirens. This approach is used when the situation does not require immediate or urgent action, allowing for a safer and more controlled driving environment while still ensuring that emergency services can reach their destination without the additional urgency required in an emergency situation.

Using lights and sirens typically indicates an emergency response, which involves a need for rapid intervention and signals to other road users to yield. Driving at high speeds and responding with urgency are also associated with emergency responses, which prioritize fast action to mitigate immediate dangers. Therefore, the defining feature of a nonemergency response is precisely the lack of lights and sirens, emphasizing a more measured and routine approach to the operation.
