i'm red and green colorblind, seriously... i drive by looking at the position of the lights. top light lit, STOP, bottom light lit, GO... middle light lit... can i make it?
i am not joking, also i don't know if there was a test for handi cap of not seeing color? but there should be, i mean there are ppl like me who have a legal license to drive and i cannot see 2 of the 3 primary stop/yield/go colors.
i forgot where but one time i was driving and i saw horizontal lights, i freaked out... i just approached the lights slowly and if traffic moved, i moved, or if someone honked, i went!
