Under what condition does the duty of the public to yield the right of way attach?

The duty of the public to yield the right of way is established primarily when both lights and sirens are being operated on a law enforcement vehicle. This is essential for ensuring the safety and effectiveness of emergency responses. The use of lights and sirens serves as a clear indication that an emergency vehicle is approaching and that other drivers should take appropriate action to clear the roadway.

When both lights and siren are utilized, they create a heightened awareness for other motorists, signaling them to yield. This combination increases the visibility and audibility of the emergency vehicle, making it clear that it has the right of way, particularly in situations where quick responses are required, such as medical emergencies, police pursuits, or fire responses.

While lights alone may prompt some drivers to yield, the siren adds an auditory signal that can alert those who may not see the lights, especially in heavy traffic or at intersections. This comprehensive approach creates a safer environment for both the responders and other road users. Thus, the condition where both lights and sirens are operational is critical in establishing the obligation for the public to yield the right of way.
