The “wheelchair” or the “disabled” sign is actually officially called the International Symbol of Acccess. Although it is meant to designate a place or transport system as wheelchair-friendly, it really isn’t kept to only the people on wheelchairs. This sign may pertain to many different disabilities whether visible or not.

Conditions symbol pertains to also includes psychological problems as well as brain development disorders like autism.
