What is NOT a criterion related to a driver's physical qualifications under FMCSA?

The choice indicating "no loss or impairment of the sense of touch" is not explicitly listed as a criterion for a driver's physical qualifications under FMCSA guidelines. The FMCSA outlines specific medical standards that relate primarily to critical functions essential for safe driving, such as vision, hearing, and the ability to operate a commercial vehicle safely without significant medical conditions that would interfere with driving abilities.

For instance, criteria such as having no diagnosis of heart disease, no history of epilepsy, and restrictions related to hypertension are detailed in the FMCSA regulations because they directly impact a driver’s capacity to maintain control of a vehicle and respond to emergencies. Lost or impaired sense of touch, while important in a general context, is not specifically mentioned in the regulations, which focus more on life-threatening conditions and those that might affect essential functions such as cognition, motor skills, and immediate responsiveness.

This distinction helps clarify the emphasis of FMCSA on serious and obvious medical conditions that would be more likely to endanger public safety if not managed properly.
