I live near a traffic light junction. During the night I hear frequent short blasts of emergency vehicle sirens. I don't think they are attending emergency calls.

I guess they don't want to stop at traffic lights. In many countries, traffic lights switch to intermittent (flashing orange) during the night and you are free to drive through if your route is clear.

If we could get hold of that technology here, it would mean quieter nights for everyone.

Worth taking a bit of money from the multi-million pound budget for black bollards.
