What must you do when you hear an ambulance siren?

When you hear an ambulance siren, the appropriate action is to pull over to allow the ambulance to pass. This response is crucial because emergency vehicles, such as ambulances, often need to reach their destinations quickly in order to provide critical care. By pulling over to the side of the road, you create a clear path for the ambulance, ensuring that it can navigate through traffic without delay.

This action not only aids in the timely response of emergency services but also is a legal requirement in many states, including Texas. Drivers should remain stopped until the emergency vehicle has passed and it is safe to return to the road. Recognizing and responding to emergency vehicles promptly is an important aspect of safe driving.
