Driving Response Vehicles

Michael Eburn says that he is asked this question by a NSW volunteer and jumps to a quick conclusion – lights and sirens don’t give you any rights.
The question was: I was told other vehicles must give way to emergency vehicles when under lights and sirens but I’ve also been told that if you’re under lights and sirens it does not give you the right-of-way. Of course you have to take care at all times but I’m interested in know what rights does the driver of an emergency services vehicles under lights and sirens have.
