The medical requirements to obtain a permit vary by state, but are usually confined to specific types of disabilities or conditions. These as a general rule include the use of any assistive device such as a wheelchair, crutches, or cane, as well as a missing leg or foot. Some states also include certain cardiovascular, pain, or respiratory conditions. About half of US states (26) include blindness as a qualifying disability enabling the person to obtain a disability parking permit for use as a passenger, and 14 states include a disabled hand as a qualifying disability. Four states include deafness (Georgia, Kentucky, Virginia, Wyoming), and two states (Virginia and New York) include mental illness or developmental disabilities as qualifying disabilities.
