In the U.S., people with epilepsy can drive if their seizures are controlled with medication or other treatment and they meet the licensing requirements in their state. How long they have to be free of seizures varies in different states, but it is most likely to be between three months and a year.[22][23] In 44 of the 50 states, the burden is placed on patients to report their condition to appropriate licensing authorities so that their privileges can be revoked where appropriate. Six states place the burden of reporting on the patient's physician.[24] After reporting is carried out, it is usually the driver's licensing agency that decides to revoke or restrict a driver's license.
