When approaching vehicles backed up at an intersection you must turn off your sirens ______ ft before reaching traffic.

• A. 150 ft
• B. 200 ft
• C. 250 ft
• D. 300 ft

Answer: (B)

When emergency vehicles approach a line of cars backed up at an intersection, turning off the siren a short distance before you reach the traffic helps keep the situation predictable and less chaotic. The siren can startle drivers who are already waiting, causing abrupt or erratic movements. By deactivating the siren about 200 feet before the intersection, you retain the visibility of lights and your presence while giving drivers time to notice, gauge the approach, and move safely out of the way. This distance strikes a practical balance: it provides enough warning and reaction time in dense traffic without keeping the loud siren blaring longer than necessary. Shorter distances may not give drivers enough time to react in heavy traffic, while longer distances unnecessarily extend siren exposure and can complicate the flow as you navigate the intersection.
