We often get questions about when and why ambulances run with lights and sirens vs. sometimes not. Here’s how it works:
👉 Dispatch sets the response code.
Every call received is assigned a priority code — Alpha/Omega, Bravo, Charlie, Delta, or Echo. These codes are based on the information given to 911 dispatchers which then tell first responders the urgency of the situation. Some codes require lights and sirens, while others do not. (For example, Alpha calls are typically minor, while Echo calls are the most serious and life-threatening.)
👉 Transport decisions matter.
Just like on the way to you, the decision to use lights and sirens while transporting a patient to the hospital depends on the severity of the medical situation and how urgently the patient needs advanced care.
👉 Calls can change.
Sometimes, as dispatchers receive more information, the nature of the call may be upgraded, downgraded, or even canceled. This may mean crews turn lights and sirens on, off, or are redirected to another emergency.
👉 Safety comes first.
Even if a call begins with lights and sirens, our crews may turn them off when entering neighborhoods or approaching homes — regardless of the time of day. This helps reduce unnecessary noise and keeps everyone safe while still allowing us to provide a quick response.
👉 Not Random, Always Reasoned.
Whether we use lights and sirens or not, the choice is based on patient needs, medical necessity, and community safety — never personal preference.
⚠️ Remember: If you ever need us, always call 911. Dispatch will make sure the right help gets to you as quickly and safely as possible.
