South Carolina does not require a physician to notify DMV when a patient has had a stroke but they will accept information sent in. Once a person's name is submitted to the DMV, and they have a new medical condition, they will most likely be turned over to the Medical Advisory Board. This Board can require additional medical information as well as a clinical driving evaluation in order to keep their license. Strokes affect people in different ways, but almost always slows their reaction times. I would recommend that you speak with a medical provider about your concern. A clinical driving evaluation could be a useful tool to see where there may be concerns that put a person at higher risk for a motor vehicle accident. Frequently, changing driving habits can have an impact on a person's safety. Check out the driving section under the Life tab on the website. It offers some good information of things to be aware of when you are driving.
