What I was disagreeing with was your implication that
*all* cases of going through amber lights were offences: you didn't
distinguish between the case where a car has plenty of time to stop at the
amber light and the case where a car is too close to the lights to stop.

You were not disagreeing with me on that point, but with someone
else.

By the way, what's the situation with lights which are only for a pedestrian
crossing (ie not for a road junction)? I thought that these always had a
flashing amber phase between red and green, during which it was legal for
cars to set off or drive across providing the crossing was clear of
pedestrians. I was surprised the other day to find a pedestrian-only
crossing where the lights went to solid amber instead of flashing amber.

There are lots like that in Liverpool - all the way along the A59 (Scotland
Road and extensions) for example.
