International Symbol of Access
The International Symbol of Access (ISA), also known as the International Wheelchair Symbol, denotes areas where access has been improved, mostly for those with disabilities. It consists of a usually blue square overlaid in white (or in contrasting colours) with a stylized image of a person in a wheelchair. It is maintained as the international standard ISO 7001, image of the International Commission on Technology and Accessibility (ICTA), a committee of Rehabilitation International (RI).
