A driver with a history of epilepsy may be certified after how many years seizure-free?

A driver with a history of epilepsy can be certified if they have been seizure-free for ten years. This is based on the Federal Motor Carrier Safety Administration (FMCSA) guidelines, which require a driver to have a significant period without seizures to ensure the safety of both the driver and the public. The ten-year seizure-free period allows for a robust assessment of the individual's condition, showing a stable state that significantly reduces the risk of seizures occurring while operating a commercial vehicle.

The other options do not align with the established guidelines for certification; a one-year or five-year seizure-free period does not sufficiently demonstrate the long-term control of epilepsy necessary for driving safely, and stating that a driver can never be certified would overlook the possibility of individuals managing their condition effectively over an extended period.
