Perhaps it's Mr Younger-Ross that need educating given the HighWay Code states the following:
29: Emergency vehicles. If an ambulance, fire engine, police or other emergency vehicle approaches using flashing blue lights, headlights and/or sirens, keep off the road.I think we should make him, and the 17 others who signed the EDM, take their test again.
194: Emergency vehicles. You should look and listen for ambulances, fire engines, police or other emergency vehicles using flashing blue, red or green lights, headlights or sirens. When one approaches do not panic. Consider the route of the emergency vehicle and take appropriate action to let it pass. If necessary, pull to the side of the road and stop, but do not endanger other road users.
