A diagnosis of epilepsy or an established medical history of epilepsy is disqualifying. (Epilepsy is defined as 2 or more unprovoked seizures.) If a person has one unprovoked seizure, they may still be able to get a 1-year certification after 5 years have passed with no seizure and no anti-seizure medications. The driver must provide documentation of clearance from a neurologist who specializes in epilepsy and understands the functions and demands of commercial driving. Anti-seizure medication or medication for epilepsy is an automatic disqualifier.
