Is it legal for deaf people to drive?

Yes, they are actually usually better drivers than hearing people because their handicap causes them to be more aware of their surroundings than a hearing person would. They also can have a system in their car that tells them when an emergency vehicle is approaching. Most deaf people don't listen to music / have the distractions. They don't talk to their friends on the phone. Most deaf people have good sight since they are losing one of the 5 senses. Some people have gotten into accidents with emergency vehicles simply because they couldn't hear but that is un common. I know a lady who did and she ended up losing her memory. So deaf people can drive and frankly are good drivers.
