The N.C. Division of Motor Vehicle's Medical Review Unit Program evaluates drivers when there are concerns that certain medical conditions might have an impact on their ability to safely operate a vehicle.
A staff of licensed medical professionals conducts thorough reviews of medical records and statements in conjunction with driving records and decides what, if any, restrictions should be placed on a driver license.
Depending on the severity of the medical condition – or if the condition worsens – the Medical Review Unit will review a driver's case on a periodic basis.
In such cases, the driver must submit updated medical documentation each time their case is reviewed. Depending on the medical condition, these updates might be required as often as every three months or as infrequent as once every three years.
