What steps should be taken at a traffic signal when responding to an emergency call?

Approaching a traffic signal with caution and ensuring safety is the correct approach when responding to an emergency call. This step is crucial for maintaining the safety of both the emergency vehicle occupants and other road users.

When an ambulance approaches a traffic signal, particularly when it is red, it is important to assess the situation carefully. The driver should slow down, look for any pedestrians or vehicles that may not be aware of the emergency lights and sirens, and be prepared to stop if necessary. This cautious approach helps prevent accidents and ensures that the ambulance can navigate through the intersection safely.

In contrast, speeding through an intersection without stopping poses a significant risk of collision and would violate traffic laws, which could compromise safety. Ignoring the traffic signal altogether disregards the rules of the road and could lead to dangerous situations. Utilizing the horn to request passage can be helpful, but it should be done in conjunction with careful observation and caution, rather than as a standalone action. Therefore, ensuring safety while approaching a traffic signal is a vital practice for emergency response driving.
