First comment - which IDIOT put a bus stop within the controlled area of a pedestrian crossing? Or put a zebra crossing near a bus stop, whichever way it happened? Second - there is no exemption to any emergency service to cross pedestrian crossings in the same way as traffic lights. Any emergency service driver should always be prepared to stop at a zebra crossing. I know the blues and twos were on, but on a bright sunny day, who can see the blue lights? What if the person was deaf? At least the driver was alert enough to slam on the anchors - perhaps your colleague was prepared for the unexpected?
