A whole load of orders telling people they "must wear a face mask", are widely ignoring the disability exemption.
Face masks are making life even more difficult for many people in many different ways.
I was shocked to get an email from Transport for London that completely failed to mention exemptions at all. And I've since seen many shops also ignoring disability exemptions.
Whilst it can be difficult to pin down the factual and/or legal basis for the raft of measures purporting to "combat the virus", there is official guidance here from the Department of Transport.
Remember you don't have to wear a face mask if you are exempt and the Government provides Guidance accordingly. There is no need to carry an "exemption card" or anything like that as disabled people are entitled to be able to enter and leave shops, transport and other public spaces on the same basis as everyone else without having to "prove they are exempt".
