As someone said above, you are allowed to move through a red light BUT only if directed by a Police Officer.
Within West Midlands Ambulance Service we are taught not to force other road users through red lights. Any decent blue light driver will be constantly assessing the junction as they approach to see if they can make it round you either by using the opposite side of the road or by slaloming through the traffic on the correct side. If we can't get through the lights stay on but we deactivate the sirens until we can move.
If we are unable to see where we are going IE past temporary traffic lights on a bend, a bridge or a hill etc, personally I turn everything off until I get a green light so users don't panic and try and move through into roadworks or with oncoming traffic stopping within the road works causing further delay once the lights go green.
Simply put, if you do it, do it safe. Don't put yourself or other road users in danger. But you could be prosecuted.
