You should look and listen for ambulances, fire engines, police, doctors or other emergency vehicles using flashing blue, red or green lights and sirens or flashing headlights, or traffic officer and incident support vehicles using flashing amber lights. When one approaches do not panic. Ask yourself if they need your help e.g.  they might be driving on the other side of the road or another lane which is empty. Otherwise  take appropriate action carefully and safely if you can to let it pass, while still complying with all traffic signs, so don’t drive through a red light, into an active bus lane or stop in a box junction unless a uniformed police officer asks you to. If necessary, pull to the side of the road and stop, but try to avoid stopping before the brow of a hill, a bend or narrow section of road. Do not endanger yourself, other road users or pedestrians and avoid mounting the kerb. Do not brake harshly on approach to a junction or roundabout, as a following vehicle may not have the same view as you.
