im doing my driving test today and im confusing myself as to the order in which the traffic lights change. i knew myself but i forget now because i got 3 different orders off the internet not i forget my orriginal one.
It can also go red-amber-green if e.g. at a pedestrian crossing where the amber means "yield if pedestrians about to cross" before it goes back to green.
But, as you say, normal traffic lights go green-amber-red-green
