i remember visiting extended family back in, i think, the early 80s. down in alabama or something. their traffic lights went green>yellow>red, as expected. but then went red>yellow>green.
In some biggest country traffic lights FSM looks like this: red->red+yellow->green->blinking green->yellow->red, and can transition to blinking yellow from any state.

in many (maybe even ‘most’) american towns and cities, there would be too many drivers going on that yellow and not waiting for the green.
They’d be running a red light

What would you expect them to do? Go straight from red to green?
That’s what normally happens
Purple.
Green!!
That’s what traffic lights do here in Spain. I don’t actually know if Red-yellow-green has any advantage
That’s the part where you spin your tires to burn
In the UK, they go Green-Yellow-Red-Yellow-Green, which seems pretty sensible to me.
Imagine green-blinking green-yellow-red-red+yellow-green.
I’ve seen that in some German places as well
All German places I’ve seen, this seems to be a national thing.
@zout No. Green, Yellow, Red, Red+Yellow, Green…
There. Are. Four. Phases.
After Yellow always comes Red. (At least in Germany)
Never noticed this, will look out for this next time I cross the border.
Czechs do this too. Gives you time to menacingly rev your engine at the car next to you.
