The solutions for these problems taken in US and Europe are different. In Europe the yellow-after-red is shown together with the red still on, strongly suggesting "no, you may not enter", and in the other direction the green often blinks once 10 seconds before it switches to yellow. In US there is no yellow-after-red, the red changes directly to green, and yellow always goes only after green (the automatic transmissions being prevalent, there is no need to shift into gear). The yellow is often long, to let the traffic on the fast roads to clear off, Also, there is usually a period of red in all directions which lets the stragglers clear off the intersection for sure before the other side goes green. This is why slipping on red just after yellow had ended is considered no big deal in US and a major no-no in Europe.

:Where I live, in Santa Cruz do Sul - Rio Grande do Sul - Brazil, we have no yellow before green, but very few traffic lights blink red once right before green. Here, slipping on red is also common, but it's also common to stretch it a bit more and confusion ensues. Continuing from what has been said below, some traffic lights in Porto Alegre even have a numeric countdown.[[Special:Contributions/108.162.212.220|108.162.212.220]] 20:06, 9 February 2014 (UTC)

In Brazil some cities have greens and red in a row, and they decrease to indicate how long the green or red will last. something like http://www.guiasjp.com/fotos_noticias/foto_1165344648.8822.jpg [[Special:Contributions/189.125.162.182|189.125.162.182]] 20:22, 5 October 2012 (UTC)
