The Blue Badge scheme is a national scheme for those who have a permanent disability which means they are unable to walk or virtually unable to walk or those who are registered blind. A blue badge is intended to help those who would be unable to visit public buildings, shops and other places unless they can park close to their destination.
The Blue Badge scheme supports people who cannot easily get around by helping them park closer to their destination. Blue Badges are also known as disabled parking permits.
