Our training says little more than if we cause an accident because of our blue light driving (not involving us per se, but someone sees us and swerves into another driver) then we a partly to blame for that accident. As for red lights... I honestly don't know - you are kind of stuck between going through the red light (*safely*) or possibly falling foul of 'impeding an emergency vehicle'. Either could land you in trouble. Me? I go through the red, and if I get a letter through the door fining me I'll ask for it to be seen by a magistrate - I'd have a good chance of persuading them that it was a reasonable action for me to take. I suppose that it could really do with some sort of official/highway code clarification.
