"The World Federation of the Deaf (WFD) stresses that deafness does not in any way limit a person's ability to drive a car or other vehicles. Consequently, a deaf driver does not constitute a risk for safe traffic."
I'd suppose if deafness was a bar to obtaining a driver's license a hearing as well as vision test would be required.

Hmmm...so, can i a hearing person listen to music on a head set.
Since hearing is not necessary?
