This is an interesting subject that begs the question.... Can deaf people obtain a driver's license? Would the license be restricted in some way?
I don't know about anywhere else but in Florida deaf people can get a driver's license. I work with a deaf guy and I asked him this. His license is not restricted but it does have a mark on it which lets police or EMTs know that he is deaf. He also has a sticker on his driver's side window that says the driver is deaf. He has a dry erase board in his car to communicate when he needs to. He also carries a pocket note pad and pen everywhere.
Interestingly (to me at least), he drives a beautiful old El Camino that sounds incredible when he hits the gas. I asked him why he would pay for something like that when he can't hear it and he told me he can feel it, and that it turns heads.
His wife is also deaf which led me to ask what arguments are like. He said there is a lot of hand waving but he doesn't dare turn his back because he can't hear her coming up behind him with a frying pan!
