Other Danger Street Sign

Certain medical conditions can affect your ability to drive safely, but having a medical condition does not mean that your driving privileges will be restricted. Whether you have an illness, injury, or you take medication that causes certain side effects, if you are diagnosed with a medical condition that may affect your driving, you should let the Department of Motor Vehicles (DMV) know.
