This weeks safety initiative

(I havent used those words since leaving a certain large multinational corporation!)

Traffic/speed control in Portugal: The flashing lights mean that the radar controls in the traffic lights in the distance are active. If you go over 50km/h (or 70 for others) the lights go red. Stay below 50, they stay green. No fines, no cops, no photographs (although I have been told a couple are fitted with cameras - as is typical here one person has said thats true, three people have said its not!). Simply if you're speeding then you're forced to slow down by being made to stop.

Very good idea especially for country towns like this one or bad stretches of road. One flaw - they tend to only get installed close to mayoral/national elections, and therefore any two bit town may get one out of greed not need whereas others miss out. Thats politics.....
