As the man said - "Colour bind drivers"
I am red/green clour blind.
Interestingly, distinguishing between red and green traffic lights is not a problem.
However....
To me, the red and amber seem pretty well the same colour, as they also are to the old style yellow street lighting. This can cause problems at night in unfamiliar areas since I cannot "see" a Red light from a distance if it is backlit by yellow street lights. I can only spot it when I am close enough to see the pole and that the light is at a different height. This is of course less of a problem than it was since the old "Deep yellow" lights are pretty well out of fashion now and the "Bright yellow" lights that are used nowadays are a diferent colour and do not cause the same confusion.
Interestingly the red light also seems significantly dimmer than the green/amber ones (A bit like the green/amber have 100watt bulbs but the red has only got a 60!) I am prsuming that to a non-colour blind person they are all equally bright!
As an aside, one thing I have noticed over the years is that I can adapt to low light levels a lot more quickly than my non-colour blind freinds and once dark adapted I can see well enough to run up and down stairs in light levels that leave non-colour blind people completly blind!
I am wondering if this is why the mutation persists. Colour blindness carries some disadvantages (Like an increaced risk of dying of bowel cancer) but there are advantages in being able to see in the dark!
