What must you do if you hear an emergency vehicle siren when driving?

When you hear the siren of an emergency vehicle while driving, yielding the right-of-way and stopping is the appropriate action to take. This ensures that the emergency vehicle, such as an ambulance, fire truck, or police car, can navigate through traffic quickly and safely to reach its destination. Stopping allows for a clear lane for the emergency vehicle to pass, which is crucial in situations where every second counts.

It's important to be aware that simply speeding up to clear the road may create additional hazards and does not guarantee a safe passage for the emergency vehicle. Likewise, pulling over to one side of the road without stopping may not provide enough space for the emergency vehicle to pass safely. Ignoring the siren entirely can lead to significant consequences both legally and in terms of public safety. Thus, yielding and stopping are essential protocols to follow when encountering an emergency vehicle approaching you with its lights and sirens activated.
