The use of lights and sirens on an ambulance is primarily designed to request other drivers to yield the right of way. When an emergency vehicle activates its lights and siren, it is indicating that it needs to reach its destination quickly, typically to provide urgent medical care or transport an emergency patient. This serves as an audible and visual cue for other motorists and pedestrians to be aware of the ambulance’s approach and to take appropriate action, such as pulling over to the side of the road.

This usage is a crucial aspect of emergency vehicle operations, as it ensures that emergency responders can navigate through traffic safely and efficiently. Yielding to an emergency vehicle is often mandated by traffic laws, reinforcing the importance of these signals in facilitating rapid medical response during emergencies.
