No, in Germany traffic lights are still red-yellow-green. But colourblind and red-green-blind (Threre is a difference, I think) people still get a driver's license. The red light is always topmost (there's no left-right scheme here).
Reminds me of a friend who was always tossing in red and green cards randomly when we played UNO. He does have a license.
But the original point of this thread seems to be done. Now there are grey lightbulbs. I'm still hoping for a fantasy-themed forum, like the old one, sometime in the future. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
You must have never seen the traffic lights in some major crossroads here in Japan.
We have up to 6 x 3 signals stacked at some points with blue arrows augmented signs.
There is no way you can tell by position only, besides, red colour is supposed to stop you by colour recognition at your marginal sight when you pay attention to pedestrians. How about counting on the fingers if it was the first or the third? <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> (Just Kidding)
I am under the impression that we are talking about two different colour blindness types.
The one that was licence rejecting was the one in which the driver could not tell if the light was red or green.
There are three sub-types under that type.
One of them is the blue shades monochromatic type, and in that case red and green cones are out of function in the retina.
Another has either red or green cones malfunctioning.
The third one is not retina related but optical nerve related and the colour signals bleed by genetic crossover of nerves.
Especially at night the driver may see nothing but one light from a distance and that colour must be discriminated at once and not after figuring out if it was at the top or the bottom or left or right of a stack.
You might want to double check if the alleged allowing of a driver’s licence to the colour-blind was true or false.
