It's no longer a legal requirement to wear a face covering on public transport in England, Scotland or Wales. We do encourage you to wear a face covering in crowded spaces, if you can. For the latest travelling safely information for England, Wales and Scotland, see our Coronavirus page.
Anyone can use your card if you want them to. Unless your ticket has been issued just to you such as a student ticket.
You might be asked to show photo ID when you use a student or concession ticket. So it's best not to share these tickets with anyone else.
