General rules
The laws in all 50 states restrict driver's licenses for persons with active seizures that are not controlled by medication and establish rules regarding when and how a license may be acquired. The usual requirements necessitate that a person be seizure-free for a specified period of time, commonly six months, but increasingly three months or more, and have a physician's statement confirming that the individual's seizures are controlled and that if the person is licensed to drive, he or she will not present an unreasonable risk to public safety.
The laws of the state you live in, not your doctor, decide whether or not you have the right to drive. Your doctor should be able to tell you what the current laws are and whether you meet the criteria for driving.
Which states require physician reporting?
Six states (California, Delaware, Nevada, New Jersey, Oregon and Pennsylvania) still require physicians to report patients who have seizures to the state, usually to the department of motor vehicles. While these statutes arguably do little to protect the public interest, they have been used to bring civil litigation against physicians who have not reported their patients to the department of motor vehicles, even in cases where patients are compliant and on medication.
