:I believe "right-hand" is used to differentiate "the opposite from the left" from "the opposite of wrong". If I say "get in the right lane", there is a chance for confusion and/or a cliche joke. If I say "get in the right-hand lane", my meaning is clearer.{{unsigned|Tryc}} | :I believe "right-hand" is used to differentiate "the opposite from the left" from "the opposite of wrong".

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.

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) | 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) | ||

In Tianjin China they have a traffic signal that is a single bar of light. If it is green it starts subtracting bar length segments. When there is about a quarter left it turns yellow and then red. It then start subtracting bar length segments from the other end until it gets to about a quarter length and then turns green again. http://www.flickr.com/photos/bob406/3428844012 | In Tianjin China they have a traffic signal that is a single bar of light.

In UK, ALL lights go Red -> red AND yellow -> green -> yellow on it's own -> red again. Red and yellow means it's about to go green and yellow on it's own means it's about to go red.
