• The impaired driver is evaluated for driver licensing according to a functional ability profile. This test correlates, in increments, the physical or medical ability of the driver with the risk categories and the vehicles the driver is permitted to operate. The person is responsible for his fitness to drive. The physician may help in patient evaluation by participation in a medical advisory board or in public education. Guidelines for 11 areas of potential driving impairments were developed in the state of Utah. These principles are illustrated with visual standards.
