Traffic jam

Getting stuck in the traffic jams is normal thing in big cities. In this situation people can’t do anything except getting annoyed. But what if (Which happens many times) an ambulance also gets trapped in the jam and the vehicles proceed at the snail’s pace? The constant beep of the ambulance is enough to make anyone anxious. How the people in the ambulance might be feeling that time? How the ambulance would manage to reach the hospital on time? What if it fails to reach hospital on time?  Is this not the responsibility of the traffic police to make way for the ambulances in the first place?
