Random question, today I was at a traffic light controlled rounderbout with box junction on the lane on my right a big lorry and i was at the frount on a red light and behind me came a polic car under blues, I moved as much as i coul without crossing the line but the police car was changing his sirens and playing with his horn pulling faces/hands going up behind me. Eventually the lights changed so moved foward enough for it to get past.
My question what it the offical thing to do in this situation? Go through the red to let it past? Or sit there?
