You are approaching a green light in vehicle A. An ambulance sounding its siren is approaching the same intersection with a red light. What should you do?

When approaching a green light while an ambulance is sounding its siren and approaching a red light, the appropriate action is to slow down and stop if necessary to avoid obstructing the ambulance. The emergency vehicle has the right of way regardless of the traffic signals because it is responding to an urgent situation.

By slowing down and stopping, you ensure that the ambulance can pass through the intersection safely and without delay. This adherence to traffic rules prioritizes the needs of emergency services, which can be critical in saving lives. It's essential to remain aware of your surroundings, especially when an emergency vehicle is present, and to act in a way that does not impede its progress.

Moving at a higher speed or ignoring the ambulance, despite having a green light, could lead to a dangerous situation, as you might enter the intersection at the same time as the ambulance, potentially resulting in a collision. Thus, stopping when necessary is the safest response in this scenario.
