What is a Code 2 response?

• A. Emergency response with lights and sirens; highest priority for arrival.
• B. Urgent response without lights and sirens; non-emergency but time-critical.
• C. Incident canceled or no incident; units return to service.
• D. Response with only sirens, no lights.

Answer: (D)

Code 2 conveys urgency without the strongest visual warning. In this system, the indication is to move quickly and alert others using the siren, but not to activate the vehicle’s lights. That audible signal alone communicates urgency to other drivers and bystanders while keeping the visual presence less conspicuous than a full lights-and-sirens response. So a response described as having only the siren and no lights best fits this level. The alternative that includes lights and sirens points to a higher-priority response, the cancellation option isn’t an active response, and a scenario with lights but no siren doesn’t match this code’s defined signaling.
