What are the conditions that qualify a driver for a Skill Performance Evaluation exemption?

A Skill Performance Evaluation exemption allows certain drivers with specific disabilities to operate commercial vehicles safely. The conditions that qualify for this exemption include limb amputation, the use of orthosis, and fixed deficits or impairments. These conditions indicate that the individual may have a significant physical challenge but can still meet the physical demands of driving a commercial vehicle with proper adaptations or devices.

Limb amputation can be managed effectively with prosthetics, allowing for sufficient control and operation of vehicle controls. Likewise, the use of orthosis can support limbs and enhances the driver's ability to safely maneuver their vehicle. Fixed deficits or impairments denote a stable condition that does not worsen and allows the driver to demonstrate adequate skill and safety in driving, as their ability to operate the vehicle does not change unpredictably.

The other options involve conditions more related to overall health or sensory abilities, which may not directly qualify a driver for the same type of exemption related to physical skill performance in the context of driving.
