I wear hearing aids, because of loud sirens on police cars. if i do not wear my hearing aids, i am practically deaf. i feel that without my hearing aids, i should not be driving an automobile. what do you think? should drivers that cannot hear, be allowed a drivers license and/or operate a motor vehicle? is this a safe driver for themselves and the other motoring public? in Tennessee, by law, a person can operate a motor vehicle, while hearing impaired. is this safe?
