What should you do if an emergency vehicle approaches an intersection with its siren on?

When an emergency vehicle approaches an intersection with its siren on, stopping immediately is the appropriate action to take. Emergency vehicles, such as ambulances, fire trucks, and police cars, have the right of way, and their sirens indicate a need for urgent passage. By stopping, you allow the emergency vehicle to navigate through the intersection without delay, which could be crucial in a life-threatening situation or for timely assistance to those in need.

Yielding to the right may not be sufficient in all circumstances, as the emergency vehicle may need to travel straight through the intersection or in directions that require full access. Speeding up to clear the intersection could create dangerous conditions, potentially leading to collisions with the emergency vehicle or other traffic. Continuing as usual would obstruct the emergency vehicle's right of way and could result in serious consequences for yourself or others. Thus, stopping immediately ensures the safety of everyone involved and facilitates the emergency response.
