From the Research

For DOT medical certification, individuals with a history of seizures should be seizure-free for at least 3 months, as recommended by the American Academy of Neurology, American Epilepsy Society, and Epilepsy Foundation of America 1. This recommendation is based on the most recent and highest quality study, which updates prior position statements on seizures, driver licensure, and medical reporting. The study suggests that a minimum seizure-free interval of 3 months should ordinarily be required before driving in all cases, and should be extended in individual cases based on review of favorable and unfavorable features by medical advisory boards. Key considerations for DOT medical certification include:

  • Seizure control and medication stability
  • Low risk of recurrence
  • Type of seizure disorder
  • Compliance with treatment
  • Side effects of medication that might impair driving ability Regular follow-up evaluations are typically required to maintain certification, and drivers should prepare by gathering all relevant medical records before their DOT physical examination. It is essential to note that individual cases may vary, and the medical examiner will require documentation from the treating neurologist to confirm seizure control and low risk of recurrence. The primary goal of this policy is to ensure public safety while operating commercial vehicles, as seizures pose significant safety risks to the driver and public. In making this recommendation, the American Academy of Neurology, American Epilepsy Society, and Epilepsy Foundation of America considered the need for national driving standards, equitable and nondiscriminatory licensing criteria, and the importance of medical advisory boards in reviewing individual cases 1. While other studies have investigated the efficacy of antiepileptic drugs and the management of seizures in various contexts 2, 3, 4, 5, the most recent and highest quality study provides the basis for this recommendation.
