Another prime example of international standarisation....
red and yellow fire mains, white and yellow gas mains, yet white pipes with a circular blue ring painted on them indicate potable water, a black ring is (you've guessed it) black water (sewage) etc. , but no doubt that's different in other parts of the world/country again too. :-)
We drive on different sides of the roads in places (no I'm not starting the debate on who's right) thank god the traffic signals are generally agreed upon, although railroad signal masts often have the order of the lamps (The way they're fitted) upside down compared to road traffic lights...
No wonder people get confused....
