Exemption card for face coverings
We know that some people who have a disability or health condition may not be able to wear a face covering safely or comfortably. If you cannot wear one, you can get an exemption card.
If you cannot wear a face covering, you can show your exemption card when needed, for example to a bus driver.
You do not need to have an exemption card, but you may feel more comfortable showing something official to confirm you cannot wear a face covering.
