When the lights suddenly change to amber and you are close, there is
always a moment where you have to decide is it safer to stop quickly or
continue through. That is why amber means "stop, only if it is safe to
do so." I personally don't have a problem with the idea of red light
cameras, as they are sensibly adjusted so that someone misjudging
slightly and going through a little late won't be caught, but someone
blatently forcing their way through red will.

Hidden cameras would remove the drivers that do have a problem with
speeding and jumping lights.


In Dorset some traffic lights have sensors in the road so that if you are exceeding the speed limit through the lights you get caught.
