i have a friend who is color-blind. he always used to get in trouble in kindergarten because he couldn't tell the difference between the blue crayon and the purple crayon, and he couldn't read the labels either. so his teacher was always yelling at him for using the wrong color. he has trouble with red, too. and he has a license. sometimes he has trouble seeing stop signs.
Today I went to the club and then I went shopping. I took my car rather than walk to confirm my doubts.
In Japan the red traffic colour is at the top of the pole, therefore a pole on the right side of the street bending at right angles have the sequence red-yellow-green; a pole on the left side but bending at right angles have the sequence green-yellow-red; pedestrian lights are always RYG from top to bottom but other signs hanging down at the middle of the street are GYR from top to bottom because the standard is that red is at the tip of the pole.
In Japan and some other countries I know of a licence may not be issued without a doctor’s certificate of good sight with or without glasses and clearing colour blindness issue too. A forged certificate is quite possible in other countries than Japan because here the test is made at the traffic head quarters (no way to forge).
The end result means that having found a colour blind with a driving licence does not mean much outside Japan but in Japan it should hit the newspapers second page if not first.
