Not really trying to contradict, yet I was taught that amber means, indeed, stop.
Unless stopping requires sharp and abrupt braking, ie: turned amber when you were already too close to stop line, or, indeed already crossed that line.
The only difference I'm pointing out is that you may still need to brake harshly to stop before stop line in your set, Mike, mine allows to cross AMBER without shaking the load on the back of the lorry or inconvenience passengers.
Nevertheless.. RED MEANS STOP. UNCONDITIONALLY.
And I don't even find it a matter of law. More of common sense- it is red so someone else gets green, and you don't collide. May be tram, may be pedestrian, may be another car.
OK.. OK.. I'll shut up for a while now
