I went to mainstream High School. Anyone who was 15 or older take the Driver's Ed class. We take our tests after the classes. When we pass, then on our 16th birthday, we go out to get our permit. One year of driving, blah blah, then the driver's license test. I took it the same manner as a hearing person. I did not have an interpreter, did not have anything. Which was okay because I could speak for myself. If only I had a bigger car, the lady that tested me was um...very very large. My whole little car tilted!
Anyways.....There's really no difference in my opinion on how we take the test. The only neat thing is we get a nice small sticker on our driver's license with an ear and a slash over it (you know the symbol for deaf). That's it.
There's no discrimination for deaf drivers.
