Question about right of the way

Hi Netters,
   Could you please help me with the following question?
   I am sorry, it may be a obvious question.

   Suppose that I am in an intersection, with red light for me.
   Behind me comes an emergency vehicle with flasers and siren.
   Should I have to proceed forward (eventhough it is red for me)
   so that the emergency vehicle can go past me.
   The situation  assumed: if I don't move, the emergency vehicle
   behind me can't proceed.

   Your answer is appreciated.
   Thanks. -Isaac
