National Registry of Certified Medical Examiners (NRCME) DOT Practice Exam

What medical condition might disqualify a driver if not under control?

1. Diabetes

2. Asthma

3. Epilepsy

4. Hypertension

The correct answer is: Epilepsy

A driver with epilepsy may be disqualified from operating a commercial vehicle if their condition is not well-controlled. Epilepsy is characterized by recurrent seizures, and if a driver experiences such episodes, it poses a significant risk not only to their safety but also to the safety of others on the road. The Federal Motor Carrier Safety Administration (FMCSA) typically requires that individuals with epilepsy demonstrate a period of seizure-free living, often ranging from six months to two years, depending on state regulations, to qualify for medical certification. While diabetes can also lead to disqualifications if not managed properly, it often depends on the individual's ability to control their blood sugar levels and the type of treatment they are adhering to. Asthma generally can be managed effectively with medication, and while it may impact some drivers, it doesn’t automatically disqualify them if they maintain control of their symptoms. Hypertension poses risks as well, but with appropriate medical management and treatment, many individuals can remain qualified to drive. The severity of the seizures and unpredictability of epilepsy make it a more critical condition for disqualification compared to the other listed medical conditions, which can often be managed with proper care and treatment plans.
