What does a yellow traffic light signal mean?

amber in Australia means speed up and try to beat the red

Amber, not yellow ( in the UK at least)

What does a yellow light mean always reminds me of a classic episode of Taxi.

Aziraphale, I think the order is red, red and orange, green, orange, red.

a small pause can prevent a big problem is excellent advice, especially in heated conversations!

I thought in the UK at least, the light turns yellow before red but ALSO turns yellow right before it turns green again

Learned a rhyme in kindergarten. Yellow means be careful, green says you may go, but red is most important it says stop you know !
